Working with native .mxf files in Adobe
P¦remiere Pro and After Effects
Note Matrox RT.X2 SD does not support working with .mxf files.
Matrox RT.X2 supports the MXF file format, which allows you to use .mxf files
that are created with the Panasonic P2 camera (in SD and 720p formats) directly
in Adobe Premiere Pro and After Effects without having to convert the files to the
traditional AVI file format.
¡ Important When using a Panasonic P2 camera to shoot material at 486p @
23.98 fps for use with Matrox RT.X2, you must set the camera to Advanced mode
(486/24pA).
Steps for using .mxf files in your projects
1 Connect your Panasonic P2 device to your Matrox RT.X2 computer as per
your device’s instructions.
¦
to load your P2 memory card for use with Matrox RT.X2. However, the device
must show up in Windows as a drive.
2 You can either edit directly from the P2 device or from the computer’s hard
drive. If you choose to edit your .mxf clips from the computer, copy the
Panasonic P2 folder structure to your computer’s hard drive. For information
structure” on page 10.
3 Import the native .mxf files into Adobe Premiere Pro’s Project panel like any
other file. To help you select your shots you can enable thumbnail view, and
add details for your .mxf files in Windows Explorer, or Premiere Pro’s
Import or Get Properties dialog box. For more information on displaying
.mxf file information, see “Displaying information for clips in Windows
Explorer” on page 8.
4 Edit your project with the native .mxf files from the Project panel, applying
effects, and mixing the .mxf files with other clips as you see fit.
5 Add Adobe After Effects compositing with a simple copy and paste or
import the .mxf files into After Effects and edit them as you see fit.
¦
Note Matrox RT.X2 does not support exporting to an .mxf file.
Chapter 2, Working with .mxf, .mp4, and .avi Files

Working with native XDCAM EX (.mp4) files in
A¦dobe Premiere Pro
Note Matrox RT.X2 SD does not support XDCAM EX files.
Matrox RT.X2 supports realtime playback of Sony XDCAM EX 1080i/p and
720p .mp4 files in Adobe Premiere Pro. Both 1080i/p HQ-mode (1920×1080)
and 1080i/p SP-mode (1440×1080) clips are supported in your 1080i/p projects,
and will be automatically scaled to your project’s frame size as needed. For
example, when you import XDCAM EX 1080i @ 29.97 fps HQ-mode
(1920×1080) clips to a 1440×1080i @ 29.97 fps project, the clips are
automatically downscaled to 1440×1080. Realtime downscaling of XDCAM EX
1080i/p SP-mode clips in SD projects is also supported as explained in “Mixing
SD and HD clips in a project” on page 20.
¦
Note Instead of importing XDCAM EX clips directly to your Adobe Premiere
Pro projects, you should copy the clips from your XDCAM EX device to your
computer’s hard drive.

Displaying information for clips in Windows
Explorer
Matrox RT.X2 extends the functionality of Windows Explorer by allowing you to
easily view and manage your .mxf and .avi files by providing thumbnail previews
(Vista and XP) and additional file details (XP only).
¦
Note You can view thumbnails and additional details for .mxf and .avi files in
any application where you can choose the thumbnails or details view, such as
Adobe Premiere Pro’s Import dialog box.
Thumbnails preview
Matrox RT.X2 allows you to view thumbnails of .mxf and .avi files in Windows
Explorer. The thumbnail will display the first frame of the clip. Without Matrox
RT.X2, only the default Windows icon would appear. In a folder containing .mxf
or .avi files, enable the thumbnails view as follows:
• In Windows Vista, choose View > Tiles or any of the icon options, such as
Large Icons, except Small Icons.
¦
Note In Windows Explorer, ensure that Always show icon, never
thumbnails is cleared in Organize > Folder and Search Options > View.
• In Windows XP, choose View > Thumbnails.
Additional file details in Windows XP
On a Windows XP system, Matrox RT.X2 lets you add additional details for .mxf
and .avi files in Windows Explorer.
°To add clip details in Windows Explorer:
1 Start Windows Explorer, and ensure that the details view is selected for the
appropriate folder by choosing View > Details.
Chapter 2, Working with .mxf, .mp4, and .avi Files

2 Choose View > Choose Details.
3 In the Choose Details dialog box, select the check boxes corresponding to
the desired “Matrox” or “Matrox P2” details. Detail names followed by
“Matrox P2” are specific to Panasonic P2 files (for example, User Clip
Name, Shooter, Shooting Location, and Scene No.).
4 Click OK.
5 To apply the change to all folders, choose Tools > Folder Options >
View > Apply to All Folders.
CreatingMatroxEZ-MXFfilesforplaybackwith
V¦FWNaotpe plications
The Matrox EZ-MXF utility is not available on RT.X2 SD because
Matrox RT.X2 SD does not support .mxf files.
Many animation, compositing, and motion graphics applications used by video
editors read Video for Windows (VFW) .avi files, but these applications are not
designed to read .mxf files. The Matrox EZ-MXF utility creates a very small
reference .avi file, along with the associated mono .wav files, from an .mxf file
without modifying the contents of your original .mxf file or its metadata. Your
VFW application plays the created .avi and .wav files, which reference the
original .mxf file.
Remarks
• Windows Media Player does not support .mxf files. You can therefore use the
Matrox EZ-MXF utility to create reference .avi and .wav files for your .mxf
files that you want to play back using Windows Media Player.
Creating Matrox EZ-MXF files for playback with VFW applications
10
• For .mxf files that have a frame size of 1440×1080, the created reference .avi
files will have a frame size of 1920×1080 and a 1.333 pixel aspect ratio. To
display these .avi files correctly in Adobe After Effects or Adobe Premiere
Pro, you’ll need to use the Interpret Footage command to change the pixel
aspect ratio to 1.0.
You can configure Matrox EZ-MXF to create only video files, only audio files, or
both types of files. By default, Matrox EZ-MXF is set to create both video and
audio files.
°To create Matrox EZ-MXF files:
1 In Windows Explorer, right-click the desired .mxf file (or selected files), and
choose Matrox EZ-MXF AVI > Configure.
2 In the Configure Matrox EZ-MXF AVI dialog box, specify the type of files
you want to create (video and/or audio), and click OK.
¦
Note The file type settings will remain in effect until you change them.
3 Right-click the desired .mxf file (or selected files), and choose Matrox
EZ-MXF AVI > Create. The reference .avi and .wav files are created as per
the folder structure for Panasonic P2 as explained in the next section.
¡ Important Once the Matrox EZ-MXF files are created, do not change the
location or name of the referenced .mxf files or your VFW program won’t be
able to locate your .mxf material. If this occurs, Matrox RT.X2 will display
an appropriate error message.
Panasonic P2 folder structure
Panasonic P2 files are organized in a specific folder structure as follows:
Chapter 2, Working with .mxf, .mp4, and .avi Files
11
When you select an .mxf file in the VIDEO folder, Matrox EZ-MXF looks for any
associated audio .mxf files in the AUDIO folder, and creates the reference .avi and
associated .wav files in the VIDEO folder. For example, if you select the file
00001A.mxf from the VIDEO folder, the reference .avi file (00001A.avi) and all
associated audio files, such as 00001A00.Mono.wav and 00001A01.Mono.wav,
will be created in the VIDEO folder. For more information on the P2 naming
convention and folder structure, see your Panasonic P2 documentation.
¦
Note If you select an audio .mxf file from the AUDIO folder, only the mono
.wav file will be created, and it will be in the AUDIO folder.
Creating Matrox EZ-HDV AVI files for playback
of large HDV clips with VFW applications
The file size limit for playing back HDV .avi files in VFW applications is 2 GB.
For example, when you play back a large HDV .avi file in Adobe After Effects,
the clip stops playing at the 2-GB point. To overcome this limitation, you can use
the Matrox EZ-HDV AVI utility to create small .avi files, and the associated
mono .wav files, that reference your large HDV clips. These reference HDV .avi
and .wav files will play back completely in your VFW application.
¦
Note For HDV clips that have a frame size of 1440×1080, the created
reference HDV .avi files will have a frame size of 1920×1080 and a 1.333 pixel
aspect ratio. To display these files correctly in Adobe After Effects or Adobe
Premiere Pro, you’ll need to use the Interpret Footage command to change the
pixel aspect ratio to 1.0.
You can configure Matrox EZ-HDV AVI to create only video files, only audio
files, or both types of files. By default, Matrox EZ-HDV AVI is set to create both
video and audio files.
°To create Matrox EZ-HDV AVI files:
1 In Windows Explorer, right-click the desired HDV .avi file (or selected
files), and choose Matrox EZ-HDV AVI > Configure.
2 In the Configure Matrox EZ-HDV AVI dialog box, specify the type of files
you want to create (video and/or audio), and click OK. The created reference
Creating Matrox EZ-HDV AVI files for playback of large HDV clips with VFW
12
files will be named Filename_Ref.avi, Filename_Ref.Mono1.wav, and
Filename_Ref.Mon2.wav. For example, if you’re creating both video and
audio files for a file named Demo.avi, your reference files will be named
Demo_Ref.avi, Demo_Ref.Mono1.wav, and Demo_Ref.Mono2.wav (only
mono reference .wav files can be created for stereo HDV clips).
¦
Note The file type settings will remain in effect until you change them.
3 Right-click the desired HDV .avi file (or selected files), and choose Matrox
EZ-HDV AVI > Create. Your reference .avi and .wav files will be created in
the same folder as your source .avi files.
¡ Important Once the Matrox EZ-HDV AVI files are created, do not change the
location or name of the referenced HDV .avi files or your VFW program won’t
be able to locate your original HDV clips. If this occurs, Matrox RT.X2 will
display an appropriate error message.
Convertinga32-bit.tgasequencetoan.avifile
with alpha
Matrox RT.X2 allows you to create a single .avi file with alpha from a 32-bit .tga
sequence. The created .avi file will contain the alpha-key information, which
means that when you place the file on the timeline in Adobe Premiere Pro, the
clip will be automatically keyed. Having only one file simplifies management
and makes it easier to include the composition in your final edit.
¦
Note You can convert 32-bit uncompressed or RLE-compressed .tga files to an
.avi file with alpha.
When selecting only one .tga file, the program automatically detects other files
with the same base name in the same folder (for example, demo001.tga,
demo002.tga, etc.), and uses these files to create the .avi file. When multiple .tga
files are selected, only the selected files will be taken to build the .avi file. The
.avi file will be created with the following naming convention:
Base Name_Compressor_Output Format.avi
For example, if the base name for your converted .tga sequence is demo, the
compressor is Matrox MPEG-2 I-frame+ Alpha, and the output format is
NTSC 4:3, the created .avi file will be named
demo_MPEG-2_I-frame_NTSC_4_3.avi.
You can create HD and SD .avi files with alpha in Matrox MPEG-2 I-frame
format. On Matrox RT.X2 SD, however, only the SD files are supported.
Chapter 2, Working with .mxf, .mp4, and .avi Files
13
°To create an .avi file with alpha from a .tga sequence:
1 In Windows Explorer, right-click the selected .tga file(s), choose Matrox
AVI + Alpha > Select Format, and then click the desired .avi output video
format, such as 1440x1080i @ 29.97 fps.
¦
Note Formats that are not supported by your Matrox RT.X2 hardware are
identified with an asterisk (*) in the list. If you create an .avi file using an
unsupported format, it will not play back in real time on your Matrox RT.X2
system.
2 Right-click the selected .tga file(s), and choose Matrox AVI + Alpha >
Configure.
¦
Note Once set, the output format and configuration settings apply to all
subsequent .tga sequences that you convert to .avi files. However, if you select
a 1440×1080i/p output format, the compressor for the .tga to .avi conversion
will automatically be set to Matrox MPEG-2 I-frame HD + Alpha.
3 From the Compressor list, select the compression format you want for your
.avi file.
¦
Note Although the Matrox uncompressed formats are available, you cannot
play back uncompressed clips in real time on your Matrox RT.X2 system.
$ Matrox MPEG-2 I-frame + Alpha Renders video to MPEG-2
intra-frame format with alpha using the 4:2:2 Profile @ Main Level at a
selected data rate (SD resolution only).
$ Matrox MPEG-2 I-frame HD + Alpha Renders video to MPEG-2

your projects. This will help shorten the amount of time it takes to open new or
existing projects.
Displaying warnings in Adobe Premiere Pro’s
Events panel
Matrox RT.X2 uses Adobe Premiere Pro’s Events panel to issue certain error
messages and warnings. To display these, choose Window > Events. For more
information about using the Events panel, see your Adobe Premiere Pro
documentation.
Mixing interlaced and progressive clips in a
project
When editing on Matrox RT.X2, you can mix interlaced and progressive clips in
the same project, as long as the clips have the same frame size and frame rate.
Both the interlaced and progressive clips will play back in real time. For example,
when working in an NTSC project you can import NTSC clips as well as 486p @
29.97 fps clips, and 1440×1080p @ 29.97 fps clips to which you’ve applied
realtime scaling as explained in “Mixing SD and HD clips in a project” on
page 20.
You should be aware, however, that when you apply effects to clips that have a
scanning mode (progressive or interlaced) that doesn’t match your project, some
undesirable artifacts may appear in your clips.
Setting up your scratch disks
20
Mixing SD and HD clips in a project
Matrox RT.X2 supports realtime playback of SD clips in an HD project, and HD
clips in an SD project. To do this, however, the clips must be scaled to your
project’s frame size. If you want the scaling to be performed when you import the
clips into your project, choose Edit > Preferences > General and select
Default scale to frame size. This option does not affect clips that have already
been imported into your project. To scale individual clips in a sequence,
right-click the clip in the Timeline panel and choose Scale to Frame Size.
Because you can also mix interlaced and progressive clips that have the same
frame size and frame rate in a project, when you apply realtime scaling to a clip it
will play back in real time even if the clip’s scanning mode (interlaced or
progressive) doesn’t match your project.
Depending on your project’s video format, realtime scaling of clips is supported
as shown in the following table:

Defining your General settings
The Matrox Playback Settings dialog box has several pages that you can use to
specify various settings for editing in Adobe Premiere Pro on Matrox RT.X2.
When you select a Matrox project preset, such as DV Standard, a Matrox
editing mode is automatically set for your project, and many settings are
optimized for editing on Matrox RT.X2.
°To specify your General settings on Matrox RT.X2:
1 Choose Project > Project Settings > General and click the Playback
Settings button.
2 Click the General tab.
3 Under Scrubbing Mode, select Frame, 1st Field, or 2nd Field to indicate
whether you want to display frames or only one field when you scrub a
sequence in the Timeline panel. For example, you may want to scrub the
first or second field to eliminate the flickering that can be seen in your
picture when you pause while scrubbing interlaced video. Scrubbing fields
can also be used to check for any dropped fields that may have occurred in
your video during a telecine process.
¦
Note If you choose to scrub fields when working with progressive scan
video, you won’t normally see a difference between scrubbing the first or
second field.
Defining your General settings

4 Under Video Luma Level, select the type of processing that you want to be
applied to luminance levels in your video when rendering and previewing
video in a sequence:
$ Broadcast Processes video using the standard legal range of luminance
levels for broadcast video. Any super black or super white luminance levels
(that is, levels that fall below the standard black level or exceed the standard
white level) are clipped.
$ Post Production Processes video for post production. Any super black
or super white luminance levels in your video are retained.
5 Under Error Reporting, select Report dropped frames on playback if
you want to be warned each time frames are dropped when you play back
video from the Timeline panel. Otherwise, clear this option.
¦
Note Once playback of the sequence has stopped, a red bar will appear over
segments of the sequence that have dropped frames (even if you don’t choose
to report dropped frames).
6 Under Frame Hold, select Enable Frame Hold if you want to use Adobe
Premiere Pro’s Frame Hold to freeze on a particular frame of a clip in a
sequence. When you do this, any Frame Hold effects applied to your clips
will require rendering. If you’ve selected Enable Frame Hold and
encounter repeated frames when playing back nested sequences or clips with
bar that don’t actually require rendering, you can clear this option. When
you do this, however, any Frame Hold effects you’ve applied will be ignored.
7 Under Premiere Pro Accelerated Effects, you can select various options
for your realtime/accelerated Premiere Pro effects. For example, you can
choose to disable certain features and specify how you want your Motion
effects to be processed. For details, see “Selecting options for accelerated
Premiere Pro effects” on page 24.
8 Under Realtime Indicator Threshold, drag the slider to set the threshold at
which Matrox RT.X2 determines that a segment in the Timeline panel is
realtime. Drag to the left to set a lower (safer) threshold, or to the right to set
a higher (more aggressive) threshold. For example, if you find that Matrox
RT.X2 does not identify any segments as being non-realtime (that is, with a
red bar) and you have dropped frames when you export your project to tape,
you can set a safer threshold to force more segments to require rendering and
avoid having dropped frames. Alternately, if you find that some segments are
identified with a red bar but they don’t have dropped frames, you can set a
more aggressive threshold.
9 Under Audio Conform/Waveform File Creation, indicate whether or not
you want audio conform and .pek (waveform) files to be created when you
import clips to your project:
Chapter 3, Defining Your Adobe Premiere Pro Settings
23
$ Create audio conform and PEK files Creates both audio conform and
.pek files.
$ Create PEK files Creates only the .pek files (audio conform files won’t
be created).
You can clear either one or both of these options to indicate that you don’t
want audio conform and/or .pek files to be created for clips imported into your
project(filesmay still be created for certain typesof clips). Thisprovides faster
editing of your project immediately after importing clips because resources
aren’tbeing used for the file generation. However, because PremierePro needs
the .pek files to draw the audio waveforms for your clips, you won’t see the
waveforms in the Timeline panel.
¦
Note Depending on the content of your project, choosing not to create audio
conform files may cause dropped frames. For any change to these options to
take effect, you’ll need to restart Premiere Pro and open your project again.
10 Under Sequence Playback, clear Postroll after stop if you don’t want any
postroll when you stop the playback of a sequence. When you do this, the
playback will stop at the current-time indicator, and you’ll see a slight jump
in the video output when the playback stops (but the correct frame will be
displayed).
11 Under A/V Sync Adjustment, drag the slider to adjust the A/V
synchronization of clips played back in a sequence. If your audio starts later
than the associated video, increase the A/V sync value. Alternately, if your
audio starts before the associated video, decrease the A/V sync value. Be
aware that if you decrease the value too much, you may experience audio
crackling.
12 Under Memory Usage, select Optimize memory usage to reduce the
amount of system memory that Matrox RT.X2 allocates to work with your
project. Although this optimizes memory usage, the changes in memory
management could affect realtime performance depending on the content of
your project. If you experience dropped frames, try clearing this option to
see if the performance improves.
13 Under Matrox RT.X2 Splash Screen, select Disable splash screen
display if you don’t want the Matrox RT.X2 splash screen to be displayed
on your computer and video monitors when you first open your project after
starting Premiere Pro. Select Disable splash screen audio if you’d like to
disable the audio associated with the Matrox RT.X2 splash screen.

effects
To select your options for processing accelerated Premiere Pro effects on Matrox
RT.X2:
1 Choose Project > Project Settings > General and click the Playback
Settings button.
2 Click the General tab.
3 Under Premiere Pro Accelerated Effects, select the options you want:
$ Disable accelerated scaling to frame size Select this if you want to
disable the realtime playback of clips that are scaled to your project’s frame
size as explained in “Mixing SD and HD clips in a project” on page 20.
When you apply a DVE or other effect that resizes a realtime scaled clip,
the full-screen image is resized, including any letterbox or pillarbox black
bars. By disabling the accelerated scaling to frame size, any black bars in
your scaled clips will become transparent, but your scaled clips will require
rendering.
$ Disable accelerated transitions Select this if you’d like to disable the
realtime/accelerated playback of Premiere Pro transitions that support this
feature. Because Matrox RT.X2 emulates Premiere Pro’s non-realtime
version of these transitions, if you don’t like the emulation you can disable
the accelerated transitions to revert to Premiere Pro’s non-realtime version
that requires rendering.
$ Accelerate Motion using Select this if you’d like realtime/accelerated
playback of Premiere Pro Motion effects. You can then select one of the
following to determine how you want the Motion effects to be processed:
• Matrox move & scale Maps the Motion effects to the Matrox
CPU-based move & scale effect, which gives the best results if you only
want to create picture-in-picture effects without rotation. If you apply
rotation when you set up a Motion effect, it will require rendering.
• Matrox 3D DVE Maps the Motion effects to the Matrox
hardware-accelerated 3D DVE effect, which supports rotation. The
picture, however, won’t be as sharp as when you map the Motion effects
Chapter 3, Defining Your Adobe Premiere Pro Settings
25
to the Matrox move & scale effect. You can map to the Matrox 3D DVE
effect only if you have a display card that supports the Matrox
hardware-accelerated effects. For more information, see “Enabling and
disabling the Matrox hardware-accelerated effects in Adobe Premiere
Pro” on page 169.

the monitor.
5 If the Pulldown Method list is available, select the pulldown method you
want to be applied to your output video (Standard 2:3 or Advanced
2:3:3:2). You should select Advanced 2:3:3:2 only if you’ll be recording
to a DV-1394 device that supports this pulldown method. Depending on your
project’s frame rate and the current master output format, a pulldown method
may automatically be selected.
6 Under Analog Setup (NTSC), select the setup level you want for your
NTSC analog video:
$ 0 IRE Applies a setup level of 0 IRE. You should select this option only
when working with a commercial DV-1394 device that uses the Japanese
analog NTSC setup of 0 IRE. For example, if the video appears too bright
when you play back DV clips on your NTSC monitor, you can change the
setup to 0 IRE to output your DV clips at the correct brightness.
$ 7.5 IRE Applies the standard NTSC setup level of 7.5 IRE.
7 Under Analog Output Type, select the type of analog video output you
want. If you’re outputting SD analog video, you can select Component or
Composite & S-Video. If you’re outputting HD analog video, the analog
output type will be set to Component.
8 Select Allow Super White to allow the highest luminance level of your
video output to exceed the standard maximum white level. Select Allow
Super Black to allow the lowest luminance level of your video output to fall

is, when you choose File > Export > Export to Tape). This lets you record
your sequence to the DV-1394 device connected to your RT.X2 system.
¡ Important Because this option requires additional system resources, you
may find that when this option is selected some effects that were previously
realtime will drop frames and require rendering (you’ll see a red bar over
these segments in your sequence). Therefore, you should select this option
only when you want to export your sequence to DV tape. When you perform
the export to tape, Adobe Premiere Pro will render the segments identified
by the red bar.

want to save to your .wav files. When capturing from a DV-1394 device,
you can capture up to two stereo files or up to four mono files. Select None
if you don’t want a particular .wav file to be created. When Matrox RT.X2
saves each .wav file, it assigns a .Stereo.wav or .Mono.wav suffix to the base
name you gave for the associated video file. For example, if you’ve named
your video file MyFile.avi, the associated stereo audio fileswould be named
MyFile.Stereo1.wav, MyFile.Stereo2.wav, etc.
Remarks
$ The channels that you choose to save to the first stereo.wav file or first two
mono.wav files will be embedded in the associated .avi file. When you
import your .avi file to the Project panel, the clip’s separate .wav files will
also be imported, and the embedded audio in the .avi file will be ignored.

• The associated .wav files for your .m2v clips are not automatically imported
to the Project panel.
• When performing a batch capture of .m2v clips, the captured video and audio
clips won’t be automatically imported to the Project panel. If you recapture
clips using batch capture, the captured clips will be imported automatically
only if you choose to delete the original media files from disk.
• It’s recommended that you don’t add handles (extra frames) to your captured
.m2v clips. If you do, the handles will be appropriately trimmed from the
video when you add the clip to your sequence, but the handles won’t be
trimmed from the associated audio.
• An associated .xmp metadata file is created for all captured and logged
(offline) .m2v clips. These files are created in your specified video capture
folder, and contain time code and other information that you provided for
your .m2v clips, such as tape name, description, and scene. You can open the
.xmp files in Adobe Bridge. Take care not to delete the .xmp files and always
keep them with their associated .m2v files. Otherwise, you won’t be able to
batch capture logged .m2v clips, and the time code information won’t appear
for your .m2v clips in the Project panel.

Capturing HDV material on Matrox RT.X2 SD
On Matrox RT.X2 SD, you can capture native HDV 1080i/p (1440×1080i/p)
material over the 1394 interface in an SD project using Adobe Premiere Pro’s
HDV capture feature. Depending on your project’s video format, you can
capture:
• HDV 1080i/p @ 29.97 fps material in an NTSC or 486p @ 29.97 fps project.
• HDV 1080i/p @ 25 fps material in a PAL or 576p @ 25 fps project.
• HDV 1080p @ 23.98 fps material in a 486p @ 23.98 fps project.
Your HDV clips will be downscaled when you scale the clips to your project’s
frame size for realtime playback as explained in “Mixing SD and HD clips in a
project” on page 20.

Exporting to a Matrox .avi file
Several software codecs are included with Adobe Premiere Pro so that you can
export your video to different formats. Your Matrox RT.X2 system adds several
Matrox codecs to the ones included with Premiere Pro. Because the Matrox
codecs use your RT.X2 hardware to accelerate rendering, they can export video
much faster than when you use a software codec.
The supported formats for exporting to a Matrox .avi file depend on your
project’s video format as follows:
Project video format
Supported export format(s)
NTSC

Selecting your MPEG-2 I-frame settings
When you select the Matrox MPEG-2 I-frame or Matrox MPEG-2 I-frame HD
format to capture or export your video using Adobe Premiere Pro, you can
specify various settings for the MPEG-2 I-frame compression.
°To select your MPEG-2 I-frame settings:
1 Click the Configure button. This displays a dialog box similar to the
following:
2 Drag the Data Rate slider until your desired data rate is displayed. The
higher the data rate you select, the better the video quality will be. The range
of available data rates depends on whether you’re using the Matrox MPEG-2
I-frame HD or SD format.
¡ Important Depending on the capabilities of your system, you may drop
frames if you select a data rate higher than about 90 Mb/sec.
3 To apply advanced settings to your MPEG-2 I-frame file, click the
Advanced button.
¦
Note The default advanced settings should provide good results for most
applications. We recommend that you change these settings only when needed
for special purposes.
4 Under Rounding Type, select one of the following:
$ MPEG-2 Rounds the AC coefficients up to the nearest whole number
when calculating the quantization coefficient.
$ Matrox Custom Truncates the AC coefficients to the lowest whole
number when calculating the quantization coefficient. In some cases, this
setting may yield less artifacts in graphics.
5 Under DC Precision, select the bit-depth precision of the DC intra block.
Selecting your MPEG-2 I-frame settings
40
¦
Note The higher the DC precision value that’s used to capture or render
your video, the more likely that the DC content will be increased at the expense
of the AC content in the encoded stream. This may result in lowering the
overall quality of the compressed stream at a specified data rate.
6 Under Zig Zag Type, select one of the following:
$ Regular Sets the regular (default) zig zag scanning pattern of the AC
coefficient of the DCT block as defined in the ISO/IEC 13818-2 (figure
7-2) specification documentation.
$ Alternate Sets an alternatezigzag scanning pattern of theAC coefficient
of the DCT block as defined in the ISO/IEC 13818-2 (figure 7-3)
specification documentation. Use this setting when capturing or rendering
video at a high data rate (that is, at a data rate of about 25 Mb/sec for SD
video, or 90 Mb/sec or higher for HD video).
7 Select the Force Frame-based DCT setting to render macroblocks as
frames rather than as fields. In some cases, graphics will yield less artifacts if
this option is selected.
8 Click OK to save your settings.

Selecting your MPEG-2 IBP settings
When capturing video to a Matrox .m2v file using Adobe Premiere Pro, the
capture format is set to Matrox MPEG-2 IBP. You can specify various settings for
the MPEG-2 IBP compression.
°To select your MPEG-2 IBP settings:
1 Click the Configure button. This displays a dialog box similar to the
following:
2 Under Data Rate (Mb/sec), you can select the encoding type and data rate
for the MPEG-2 IBP compression.
$ Encoding type From this list, select one of the following:
• Constant bit rate (CBR) Video is compressed at your selected target
data rate, which is useful when you need to limit or predict the size of
your .mxf file. However, if your video is very complex (such as scenes
with many colors or sharp edges), you’ll need to select a high data rate
to avoid having frames of very blocky video in your file.
Selecting your MPEG-2 IBP settings
42
• Variable bit rate (VBR) Video is compressed at varying data rates
based on the complexity of the video. The target data rate you select is
used as the average data rate for the compression.
$ Min, Target, and Maxsliders Use these sliders to select your desired data
rate. The higher the target data rate you select, the better the video quality
will be. Only the Target slider will be available if you selected Constant
bit rate (CBR). If you selected Variable bit rate (VBR), all three sliders
will be available so that you can set the minimum, target, and maximum
data rates for the video compression.
3 Under GOP Structure, you can customize the GOP structure for the
MPEG-2 IBP compression as follows:
$ GOP length Determines the number of frames in the GOP (Group of
Pictures).
$ Subgroup length Determines the subgroup length of B-frames and
P-frames in the GOP, after the initial I-frame. For example, a subgroup of
3 appears as “BBP,” and a subgroup of 2 appears as “BP.” The available
subgroup lengths depend on your selected GOP length.
4 Under Profile, the 4:2:0 profile is selected, which uses 4:2:0
luminance/chrominance sampling and is suitable for broadcast transmission
and distribution on DVD.
5 Under Motion Estimation, drag the slider to adjust the quality of the
motion estimation used for the video compression. The default setting gives
good results for most video. However, if you have a lot of fast motion in your
video, such as fast-paced sports footage, you can get better results by
dragging the slider to the right (towards Slow/High quality). This improves
the quality of the motion estimation, but decreases the speed of the video
compression. Alternately, if you have mostly slow-paced video, you may
want to drag the slider to the left (towards Fast/Low quality) to decrease
the quality of the motion estimation and speed up the video compression.
6 Click OK to save your settings.

Exporting your sequence to tape
Your Matrox RT.X2 system lets you export your Adobe Premiere Pro sequence to
tape using DV-1394 or RS-422 device control. You can use Matrox DV/HDV
device control to control DV-1394 devices. For RS-422 devices, you can use
Adobe Premiere Pro’s serial device control as explained in your Adobe Premiere
Pro documentation.
Preparing your tapes for recording
To use device control, the tape on which you’ll be recording your material must
contain continuous and consecutive time code. You can stripe your entire tape
with time code by recording black video for the duration of the tape.
¦
Note The format of your DV tape must match the format you’re recording. For
example, if you set your DV-1394 device to record in DV/DVCAM format, your
tape must be striped entirely in DV/DVCAM format. Mixed format tapes are not
supported.
Avoiding missing frames when exporting to DV
tape
When performing an export to tape on some DV-1394 devices, a delay may occur
between the time the device starts recording and the time that Adobe Premiere
Pro starts to play back your project. This may result in the first video frames of
your project not being recorded to tape. To ensure that your export to DV tape
does not miss any frames, you can delay the playback of the project that you are
exporting.
To do this, you will need to do a test export with your DV-1394 device to
determine the number of frames that are missing from the start of your project on
the DV tape. In the Adobe Premiere Pro Export To Tape dialog box, select
Delay Movie Start and enter the number of frames you’ve determined are
missing from your project multiplied by 4 (to convert the value to quarter
frames). If needed, adjust this amount until you obtain a frame-accurate or near
frame-accurate export to tape.
¦
Note If your exported video is frame-accurate, but you’re missing audio at the
start of your project on the DV tape, simply add a few frames of black and silence
at the start of the sequence. If you do this, you may not need to use the Delay
Movie Start.

Exporting to DV tape using DV-1394 device
control
You can use Matrox DV/HDV device control when exporting your Adobe
Premiere Pro sequence to a DV-1394 device. DV-1394 export to HDV, however,
is not supported for 720p projects.
°To export your sequence to tape over the 1394 interface:
1 Open the project and activate the sequence you want to export to tape.
2 Make sure your DV-1394 device is properly connected and turned on.
3 Unless you’re exporting to an HDV device, make sure that you’ve enabled
the DV-1394 output for export to tape and selected a DV-1394 output format
as explained in “Selecting your DV-1394 output settings” on page 27.
¦
Note If you’re exporting to an HDV device, Premiere Pro will detect that
video will be exported in native HDV format. (Matrox RT.X2 SD does not
support exporting to an HDV device.)
4 If you’re using a camcorder, switch it to VTR mode.
5 Load a striped recordable tape into your DV-1394 device.

Creating an SD project in 16:9 format
When editing on Matrox RT.X2, you can choose to work with SD source video
that’s been recorded in either the 4:3 standard TV screen format, or the
widescreen 16:9 format.
°To create an SD project in 16:9 format on Matrox RT.X2, do the following:
1 Record your video onto tape with your camera set to the widescreen 16:9
format. The video will be recorded as horizontally compressed 4:3
(anamorphic) video.
2 Start Adobe Premiere Pro and select the appropriate Matrox widescreen
preset (such as DVCPRO Widescreen). This ensures that the effects you
create on Matrox RT.X2 will be displayed with the correct proportions when
viewed in 16:9 format.
3 Capture your video clips as you normally would. Select the 16:9 display
option on your NTSC or PAL video monitor to “unsquish” the video and
play it back in widescreen format without distortion.
4 If you create animations, titles, or graphics for your project using a program
that lets you set the pixel aspect ratio, use the appropriate setting for 16:9
display:
$ For NTSC or 486p video, set the pixel aspect ratio to 1.185.
$ For PAL or 576p video, set the pixel aspect ratio to 1.422.
If you can’t set the pixel aspect ratio, create your image at 864×486 for
NTSC or 486p video, or at 1024×576 for PAL or 576p video. After you’ve
created your image, resize only its width to 720. When you resize the image,
your text or graphic will appear elongated on your computer screen.
5 Edit your project as you would a standard 4:3 project.
¦
Note Be aware that if your video monitor is displaying in 4:3 format, certain
effects may appear elongated because of the horizontal scaling. Setting your
monitor to 16:9 will display the effects with the correct proportions.
6 Record your finished project onto tape. Remember that you’ll need a
monitor capable of displaying material in 16:9 format to properly view your
master tape.

• Use and modify clips that have Matrox Flex CPU effects applied to them
interchangeably between Adobe Premiere Pro and Adobe After Effects. For
example, you can apply a Matrox color correction to your clip in Adobe
Premiere Pro and import that clip into Adobe After Effects and vice versa.
Realtime means that you can play back and record your effects onto tape without
having to render them. This gives you creative freedom to experiment with
different effects and change your mind as often as you want. You’ll instantly see
the changes you make on your video monitor. Effects in Adobe Premiere Pro
other than those listed above are not realtime, and therefore require rendering.
For guidelines on setting up your realtime effects, see “Matrox RT.X2 realtime

Transforming your clip
Many of the Matrox effects allow you to adjust the scale, position, and rotation of
a clip by applying various transform settings. You can adjust the transform
settings in two ways:
you want.
• Work directly in Adobe Premiere Pro’s Program Monitor using your mouse.
For example, click the desired transform button (Position, Scale, Rotation,
or Rotation Center Offset), then click and drag within the Program
Monitor to make your adjustments. To do this, you’ll need to activate the
transform controls for use in the Program Monitor. For more information,
see “Transforming a clip in the Program Monitor” on page 54.
¦
Note If you are working with the Matrox crystallize, shadow, mask, mask
blur, mask mosaic, or shine effect, the transform settings will apply only to
your mask or shadow and not the entire clip.
Using the transform controls
To apply various transform settings to your clip using the transform controls in
the Effect Controls panel, click the triangle next to the Transform property to
expand it:
You can enter the values you want in the text boxes or drag the appropriate
sliders.
• (X, Y, Z) Position Use these controls to position your clip on the x
(horizontal), y (vertical), and z (depth) axes. Values of (0,0,0) pixels align
the center of your clip with the center of the screen, and positions are
measured from this point. You can enter positive or negative pixel values to
move your clip right or left (x), up or down (y), and forward or backward (z).
Chapter 4, Setting Up Realtime Effects with Adobe Premiere Pro
53
• (X, Y) Scale Use these controls to make your clip smaller or larger.
Full-screen size is represented as 100%. You can shrink your clip to 0% or
enlarge it to 1000%. Note, however, that by enlarging your clip, the
resolution may become blurry. You can adjust the size controls individually,
or if you select Fixed Aspect Ratio, you only need to adjust the x axis.
Adjusting the percentage on the x and y axes changes your clip’s width and
height, respectively.
¦
Note Some effects, like Matrox surface finish, include a Z Scale property
that allows you to adjust the depth of the effect.
• (X, Y, Z) Rotation Use these controls to set the number of times the clip
spins. Each rotation of 360° produces one spin on the selected axis. You can
have positive or negative rotation from -360° to 360°.
• (X, Y, Z) Rotation Center Offset Use the Rotation Center Offset
controls to set the pivot point, or center of rotation, of your clip on the x
(horizontal), y (vertical), and z (depth) axes. When Rotation settings are
applied, your clip spins around this point. You can use positive or negative
pixel values to offset your clip on each axis.
In the illustrations below, notice how different Offset values can affect the
rotation of the cube.
Z
X
Z
X
Y
Y
Figure 1: Offset at 0,0,0
Figure 2: Offset at 100,0,0
In Figure 1, the Offset values are (0,0,0), so the center of rotation for the cube is
where the x, y, and z axes meet. In Figure 2, the Offset value for the x axis is set
to 100, thus moving the cube and the pivot point to the right, so when the cube is
rotated, it has a wider arc when spinning around the axes.

Applying a mask to your effect
Many of the Matrox effects allow you to add a mask to define the area where you
want to apply your effect. For example, you may want to apply a color correction
to only one area of your clip and leave the rest of the clip untouched.
Adding a mask to the chroma or luma key effect and selecting Transparent
Outside Mask lets you disable keying in the area outside the mask so that only
the underlying image appears outside the mask. For example, you can define a
mask area where you want the keying to be performed, and show only your
underlying image outside the mask. This is useful if you’re having problems
keying on an area at the edges of your foreground image.

Creating a primary color correction
Color correction is important for all productions, whether you want to achieve
continuity when cutting between shots, ensure broadcast safe levels, or establish
and emphasize a “look.” Matrox color correction provides basic proc amp
control, three-way color correction complete with master, shadows, midtones,
and highlights control, and input and output level control. You can also easily
match colors with a reference shot. For more information about color matching,
see “Matching colors between two clips” on page 70.
¥ Tip Adobe Premiere Pro includes a workspace setup that is optimized for
working with clips and effects to facilitate color correction. To prepare your
workspace for color correction, choose Window > Workspace > Color
Correction.
°To set up a Matrox primary color correction:
Click the triangle next to Matrox Color Correction (Primary) or Matrox Color
Correction (Primary - Advanced) to expand the property list.
¦
Note The RGB Curves and Tonal Range settings are available only with the
advanced versions of the Matrox primary and secondary color correction effects.
Because the advanced versions of these effects require additional system
resources, you should apply them only if you want to use the RGB Curves or
Tonal Range settings.
• Enable Split View Select this option to split your clip into two sections in
the Program Monitor and on your video monitor. One section will display
your clip as you adjust the color correction controls, and the other section of

¡ Important This option is for preview only. You should clear it before you
render your clip, otherwise the split will appear in your video output.
• Proc Amps The processing amplifier (proc amp) controls allow you to
adjust different aspects of your clip:
$ Hue Adjusts the tint of the colors in the image.
$ Contrast Adjusts the difference in luminance between the lightest and
darkest areas of the image.
$ Brightness Adjusts the level of black in the image.
• RGB Curves Lets you use curves to adjust the red, green, and blue color
channels of your clip individually, or use a master curve to adjust all color
channels simultaneously. For more information, see “Using RGB curves” on
page 63.
• Color Balance These controls let you adjust the mixture of colors in your
clip.
$ Tonal Range Allows you to fine-tune the tonal ranges of your clip by
reducing the range of pixels included for shadows, midtones, or highlights.
For more information, see “Adjusting tonal range” on page 65.
$ Graphical Allows you to see a graphical representation of your changes
when you adjust the color balance settings. You can also modify most of

• Mask Allows you to apply a mask to your effect. For more information,
see “Applying a mask to your effect” on page 57.
Using Split View
The Split View option allows you to split your clip in two for preview on your
Program Monitor and your video monitor. One section displays your clip as you
adjust the color correction controls, while the other section of the clip remains
unchanged.
There are two ways to enable Split View. You can select the Enable Split View
option in the Effect Controls panel, or work directly in Adobe Premiere Pro’s
Program Monitor using your mouse.

The area within the split view rectangle will display any color correction you
make, while the area outside remains unchanged.
In the following example, the split view rectangle has been moved to display the
color correction in the area surrounding part of the Chinese character on the wall:
Remarks
• The Split View option is for preview only. You should disable it before
rendering your material, otherwise the split will appear in your video output.
• If you are working in Adobe After Effects, you should enable Live Update
mode so that any movement of the split rectangle is reflected in the
Composition panel as it occurs.
• If you enable Split View and create a mask outside the split view rectangle,
you will not be able to see it. The mask will only be visible when you move
the split view rectangle directly over it. If you invert a mask that is not in the
split view rectangle area, the whole clip will be inverted since the mask is
ignored.

Using RGB curves
¦
Note The RGB Curves settings are available only with the advanced versions
of the Matrox primary and secondary color correction effects.
With RGB curves, you can individually adjust the red, green, and blue color
channels across the entire tonal range of your clip, or adjust all three color
channels simultaneously with a master curve. RGB curves allow you to achieve
color effects that would be difficult, if not impossible, to achieve using the Color
Balance settings, and also give you a high degree of control over the color
channels in each tonal range. For example, you can easily add a red, green, or
blue tint to your clip, or use the master curve as a way to adjust the brightness and
contrast of your clip.
Each curve is displayed on a grid with the horizontal axis representing the input
or current pixel value, and the vertical axis representing the output value of the
pixel after the curve adjustment is applied. By default, a curve starts as a straight
line with two end points, one at the bottom left of the grid (shadows), and the
other at the top right of the grid (highlights). Before any adjustments are made,
each point on the curve has the same input and output value.

Creating a primary color correction
64
Click the R, G, or B button to select the curve corresponding to the color channel
you want to adjust, or click the Master button for the master curve, and then drag
the curve to obtain your desired effect. For example, click the R button and drag
the top right end point towards the top left of the grid to increase the slope of the
curve and add red to the clip. Drag that same point towards the bottom right of
the grid to decrease the slope of the curve and remove red from the clip. Clicking
the Enable button will show/hide any adjustments you have made to the RGB
channels at any time (you do not need to click Enable to start adjusting the
curves).
¥ Tip For increased precision, hold down the ALT key while you drag the curve,
or the CRTL key to change your cursor into a crosshair that will help you align
your curve to the grid.
You can add up to 14 control points to each curve in addition to the two default
end points. These control points act as anchors that allow you to lock your curve
so adjustments can be applied only to specific tonal ranges. Click on a curve to
add control points, and hold the SHIFT key while clicking a control point to
delete it (end points cannot be deleted). Adjusting the points in the top right area
of the grid affects highlights, the middle area affects midtones, and the bottom
left area affects shadows. For example, the following S-shaped master curve adds
contrast in the midtones range, without creating any completely black or white
areas.

¥ Tip By applying a mask to your clip, you can adjust the RGB channels for that
specific area of your clip, or invert the mask to isolate that same area from being
affected by your RGB adjustments.
Adjusting tonal range
¦
Note The Tonal Range settings are available only with the advanced versions
of the Matrox primary and secondary color correction effects.
Using the tonal range curves allows you to fine-tune the range of pixels that are
affected when you make a color correction to the shadows, midtones, or
highlights of your clip using the color balance graph. For more information, see
“Using the color balance graph” on page 66.
The histogram shows the distribution of pixels in each tonal range of your clip. In
the following example, the histogram represents a clip with a high amount of
shadows (left), a lesser amount of midtones (middle), and an even lesser amount
of highlights (right).
0
1
2
0 Shadows 1 Midtones 2 Highlights
Click the Shadows, Midtones, or Highlights button to select the curve
corresponding to the tonal range you want to adjust, and then drag the curve as
desired to reduce the number of pixels to be included in each tonal range.
¦
Note You cannot increase the number of pixels in a tonal range. For example,
you can’t extend the shadows curve into the highlights range.
Creating a primary color correction
66
Using the color balance graph
The color balance graph allows you to modify the Color Balance settings for
each tonal range directly within the color maps. You can also perform an auto
balance or a color match using the buttons beneath the color maps. For more
information, see “Performing an auto balance” on page 69 and “Matching colors
between two clips” on page 70. Depending on which color map you use, you can
adjust your clip globally, or only the shadows, midtones, or highlights.
You can drag the handle in the center of any color map to adjust the color balance
(Hue and Saturation) for a specific tonal range, such as to adjust the color
balance globally throughout your clip using the Master color map, or adjust the
color balance of only the shadows using the Shadows color map. Drag the
handle toward a color you want to increase in your clip, or away from a color you

As you increase the Low Gain setting, more pixels are partially
affected by the color correction. If you decreasethe Low Gain control,
less pixels are partially affected.
A Low Gain setting of 100 provides the widest range for maximum
color correction. Alternately, a gain setting of 0 creates a key where
saturation values are either completely affected or left untouched. You
can think of the Low Gain control as defining an “Affected to
Untouched” range for keying the pale colors in your image.

you use it to set the range of higher saturation values you want to be
partially affected based on the value set by the High Clip control. As
you increase the High Gain setting, less pixels are partially affected
by the color correction. If you decrease the High Gain setting, more
pixels are partially affected. You can think of the High Gain control
as defining an “Untouched to Affected” range for keying the vivid
colors of your image.
$ High Clip This control is similar to Low Gain, except you use it to
select the higher saturation values to be keyed.
¦Note The values you can select using the Low Clip and Low Gain
controls are dependent on the High Clip and High Gain controls, and
vice versa. This prevents the low and high controls from keying on the
same values.
• Luma Key This type of key lets you select areas to be keyed (affected
by the color correction) based on their luminance value.
$ Enable Select this to enable the Luma Key properties and luma key
indicator in the selective key graph.
$ Low Clip Use this to select the lower (darker) luminance values to
be keyed. A Low Clip setting of 0 represents black, and a setting of

255 represents white. Intermediate settings represent different shades
of gray, from very dark to very light gray.
$ Low Gain Use this to set the range of luminance values you want
to be partially affected based on the value set by the Low Clip control.
Asyou increasethe Low Gainsetting, moreluminance valuesbecome
partially affected by the color correction.
A Low Gain setting of 100 provides the widest range for maximum
color correction. Alternately, a gain setting of 0 creates a key where
the luminance values are either completely affected or left untouched.
You can think of the Low Gain control as defining an “Affected to
Untouched” range for keying the dark areas of your image.
$ High Gain This control is similar to Low Gain, except you use it
to set the range of luminance values you want to be partially affected
based on the value set by the High Clip control. You can think of the
High Gain control as defining an “Untouched to Affected” range for
keying the lighter areas of your image.
$ High Clip This control is similar to Low Clip, except you use it to
select the higher (brighter) luminance values to be keyed.
¦Note The values you can select using the Low Clip and Low Gain
controls are dependent on the High Clip and High Gain controls, and
vice versa. This prevents the low and high controls from keying on the
same luminance values.

Creating a color pass effect
You can use the Matrox secondary color correction to create a color pass effect to
convert your clip to black and white, with the exception of one specified color.
This can be useful if you want to isolate a single color to make it prominent.
In the following example, the pink color of the girl’s shirt has been retained,
while the rest of the clip has been converted to black and white:
Pink shirt is isolated,
while the rest of clip is
grayscale.
°To perform a color pass effect:
1 Click the Auto Key eyedropper in the selective key graph and click and drag
anywhere on your clip to create a rectangular area containing the color you
want to isolate.
2 Under Proc Amps, set the Saturation to 0.
3 Select Invert Key.
If you have more than one object of the same color but you want to isolate only
one of those objects, you can apply a mask and use the Expand Outside Mask
option to isolate the area that contains the color you want to remain intact. For
example, if you have a clip that has two roses that are the same red and you
would like only one of them to remain red, you can do the following.
1 Click the auto key eyedropper in the selective key graph and click and drag
anywhere on your clip to create a rectangular area containing the color you
want to isolate.
2 Under Proc Amps set the Saturation to 0.
3 Select Invert Key.

Overview of the chroma key effects
You can use the Matrox realtime plug-in to apply a chroma key or chroma key
shadow effect to make certain areas of a foreground image transparent based on a
color in that image, so that an underlying image can show through.
In the following example of a chroma key effect, our foreground image is a video
clip of a woman sitting in front of a green backdrop, and our underlying image is
a video clip of a sand dune:
+
Foreground image
Underlying image
By chroma keying on the particular shade of green in the backdrop of the
foreground image, the backdrop area becomes transparent and the corresponding
area of the underlying image shows through in the composite image as follows:
=
Result of chroma key
¡ Important The chroma key shadow effect includes controls for fine-tuning
shadows in your effect. It is best to use the chroma key shadow effect when you
are performing a chroma key without any additional effects. If you want to apply
additional effects to your chroma key, you will get more desirable results by
using the chroma key effect without shadow controls. For example, if you want to
apply a DVE to your chroma key, you should use the chroma key effect and not
the chroma key shadow effect.

Creating a chroma key or chroma key shadow
effect
To set up a Matrox chroma key or chroma key shadow effect, click the triangle
next to Matrox Chroma Key/Matrox Chroma Key Shadow to expand the
property list:
• Graphical Provides a graphical representation of the chroma key controls
that you can use to select your key colors, and also lets you perform an auto
key.
$ Map Lets you select your key colors within a circular graph that contains
a color spectrum.
$ Plot Displays a plot of the colors present in your clip so that you can
select the particular colors on which you want to key.
$ Show Key Click this button to display the matte used to create your key
effect. This enables you to further refine your key. For example, when you
display the matte, your key color (such as green) appears as black, and
opaque areas appear as white. If you notice some white spots that you want
to key, you can adjust the key controls until the undesired white spots
disappear.
Chapter 4, Setting Up Realtime Effects with Adobe Premiere Pro
93
$ Auto Key Click this button to automatically key on the most common
color at the current frame in your clip (except gray).
For details on selecting key colors within the graph or performing an auto
key, see “Using the chroma key graph to modify key colors and perform an
auto key” on page 95.
¦
Note You must expand the Graphical property in order to see the indicator
when adjusting the chroma key controls.
• Hue Use this to rotate the indicator around the perimeter of the color
spectrum so that you can select different hues (colors) on which to key.
• Aperture Use this to widen or narrow the aperture of the indicator to
increase or decrease the range of colors on which you want to key.
• Saturation Use this to select colors that have a particular saturation value.
Pale colors have a low saturation value and are located at or near the center
of the spectrum. Vivid colors have a high saturation value and are located at
or near the perimeter of the spectrum. Because pale colors have low
saturation, you’ll find them more difficult to key on than the vivid colors.
• Saturation Threshold Use this to proportionally increase or decrease the
region outside of your saturation range. This controls how closely the
Saturation value must match the key color before a region becomes
transparent.
For example, after applying a chroma key effect to a foreground image that
includes dark areas or shadows that you want to preserve in your effect, you
may find that these areas have become semi-transparent. By adjusting the
Saturation Threshold, you can eliminate the key color from these dark areas,
so that they’ll become completely opaque.
• Softness Use this to soften the edges of your key by blending parts of
your foreground image with your underlying image. This makes certain
areas of your foreground image partially transparent instead of completely
transparent or opaque.
• Spill Removal Use this to remove the contamination (spill) that your key
color may leave on or around the edges of your foreground image. Spill is
usually caused by light reflecting from your solid color backdrop (key color)
onto your foreground image. Spill Removal replaces your key color from
the “spill areas” with the opposite color in the spectrum, which returns a
more natural look to these areas.
• Chroma Suppression Use this to remove any tint that your key color
imposes on your foreground image. For example, if your solid color
backdrop (key color) is green and you are using a person in your foreground
image, the person’s skin may have a green tint. You can adjust the Chroma

Suppression to replace the green tint with the opposite color in the
spectrum to return the person’s skin to a more natural-looking color.
¦
Note The following properties (Luminance and Shadow Suppression)
are only available in the chroma key shadow effect.
• Luminance Use this to adjust the luminance of your shadow. Negative
values increase the brightness of the shadow, while positive values decrease
the brightness.
• Mask Allows you to apply a mask to your effect. For more information,
see “Applying a mask to your effect” on page 57.
• Transparent Outside Mask Select this option to apply transparency
outside the mask area. This allows you to define a mask area where you want
the keying to be performed, and show only your underlying image outside
the mask. For more information, see “Applying a mask to your effect” on
page 57.
• Invert Key Select this to invert the key selection, giving you the opposite
result of what you originally selected.
• Show Key as Output Select this to display the matte used to create your
key effect. This enables you to further refine your key. For example, when
you display the matte, your key color (such as green) appears as black, and
opaque areas appear as white. If you notice some white spots that you want
to key, you can adjust the key controls until the undesired white spots
disappear.

Creating a cube effect
The Matrox cube effect lets you map video or graphics to the faces of 3D cubes.
These cubes can then be rotated in 3D space to create transition effects such as
those you often see during sports broadcasts.
The Matrox cube effect supports up to three video sources (one primary source
that the cube effect is applied on, and up to two additional sources). If you want
to use additional sources in your cube effect, the additional source clips must be
placed below, and in the same segment as, the primary source. Each additional
source is identified by applying the Matrox Source Identifier effect to the clip.

• Crystallize Alpha Channel Enables alpha for the crystallize effect, so the
crystals will remain visible even on the anti-aliased edges of a title or DVE.
This option is enabled by default, but can be cleared if you find that the
crystals make your title difficult to read.
¦
Note Crystallize Alpha Channel is applicable only when your source clip
or an effect applied to your source clip contains alpha key information. For
example, if you apply the crystallize effect to a clip with no alpha key
information and scale it down using Adobe’s Motion effect, the crystals will
not be visible on the edges of your clip because the Motion effect is the last
effect applied, and there is no alpha key information to crystallize. Whereas,
if you apply a Matrox 3D DVE to the same clip and then you apply the
crystallize effect, you will be able to apply and see the crystallized edges,
because the Matrox 3D DVE effect contains alpha information.

Creating a garbage matte effect
The Matrox 4-point, 8-point, and 16-point garbage matte effects let you use
individual control points to determine the shape of a garbage matte applied to a
clip to superimpose it onto another clip. You can use these effects to create a
garbage matte for cropping unwanted objects from a foreground image in a
chroma or luma key effect. For example, by applying a garbage matte to your key
foreground image, you can drag up to 16 control points to crop specific areas of
your clip and show only your underlying image outside the matte.

Overview of the luma key effect
You can use the Matrox realtime plug-in to apply a luma key to make certain
areas of a foreground image transparent based on the luminance in that image, so
that an underlying image can show through.
In the following example of a luma key effect, two video clips are combined to
produce the effect of two cowboys riding through fire. Our foreground image is a
video clip of a ring of fire against a black background, and our underlying image
is a video clip of two men riding horses:
+
Underlying image
Foreground image
By luma keying on the particular luminance (brightness) of the black areas in the
foreground clip, these areas become transparent and the corresponding areas of
the underlying image show through in the composite image as follows:

Creating a luma key effect
To set up a Matrox luma key effect, click the triangle next to Matrox Luma Key
to expand the property list:
• Graphical Allows you to see a graphical representation of your changes
when you adjust the property settings. You can adjust the luma key
properties directly in the graph to select the luminance values on which you
want to key. For more information, see “Using the luma key graph” on
page 112.
• Transparency Use this control to set the transparency level of your key
effect. Higher values indicate higher transparency. For example, a
Transparency value of 100 makes the keyed area in your foreground image
completely transparent, leaving the underlying image visible.
• Low Clip Use this to select the lower (darker) luminance values to be
keyed. A Low Clip setting of 0 represents black, and a setting of 255
represents white. Intermediate settings represent different shades of gray,
from very dark to very light gray.
• Low Gain Use this to set the range of luminance values you want to be
partially transparent based on the value set by the Low Clip control. As you
increase the Low Gain setting, more luminance values become partially
transparent to give you a softer-edged key.
A Low Gain setting of 100 provides the widest range for maximum softness.
Alternately, a gain setting of 0 creates a hard key where the luminance values
are either completely transparent or opaque. You can think of the Low Gain

control as defining a “Transparent to Opaque” range for keying the dark areas
of your foreground image.
• High Clip This control is similar to Low Clip, except you use it to select
the higher (brighter) luminance values to be keyed.
• High Gain This control is similar to Low Gain, except you use it to set the
range of luminance values you want to be partially transparent based on the
as defining an “Opaque to Transparent” range for keying the lighter areas of
your foreground image.
¦

• Mask Allows you to apply a mask to your effect. For more information,
see “Applying a mask to your effect” on page 57.
• Transparent Outside Mask Select this option to apply transparency
outside the mask area. This allows you to define a mask area where you want
the keying to be performed, and show only your underlying image outside
the mask. For more information, see “Applying a mask to your effect” on
page 57.
• Invert Key Select this to invert the key selection, giving you the opposite
result of what you originally selected
• Show Key as Output Select this to display the matte used to create your
key effect. This enables you to further refine your key settings. For example,
when you display the matte, areas of your clip that are completely
transparent appear as black, and opaque areas appear as white. If you notice
some white spots that you want to key, you can adjust the key controls until
the undesired white spots disappear.
Using the luma key graph
The luma key graph contains a luminance spectrum and a luminance eyedropper.
You can drag the handles in the luminance spectrum to adjust the Transparency,
Low Clip, High Clip, Low Gain, and High Gain properties.
Eyedropper
Chapter 4, Setting Up Realtime Effects with Adobe Premiere Pro

• Plot Click this button to see the luminance spectrum with a plot that shows
each luminance value present in your image as a vertical line in the
histogram. A longer line indicates a higher amount of pixels in your image of
that line’s luminance value. You can drag the handles in the luma plot
spectrum to adjust the Transparency, Low Clip, High Clip, Low Gain, and
High Gain properties. Any adjustments made affect the shape and size of the
luminance selector in the Luma Plot.

Creating a shadow effect
The Matrox shadow effect lets you project a realistic shadow from any source
containing key information, such as DVEs and titles with an alpha channel. You
can tint the shadow, and position, scale, and rotate it to match the angle of the
surface on which it is cast. Applying blur to the shadow can simulate the realistic
look of diffused light being projected on the source.
¦
Note If you are working in HD, the Matrox shadow effect may require
rendering when combined with other effects.
°To set up a Matrox shadow effect:
Click the triangle beside Matrox Shadow to expand the property list.
¡ Important Either your source clip or an effect applied to your source clip must
contain alpha key information in order to create a shadow effect. For example, if
you apply a shadow effect to a clip with no alpha key information and scale it
down using Adobe’s Motion effect, you won’t see any shadow because the
Motion effect is the last effect applied, and there is no alpha key information to
create the shadow effect. Whereas, if you apply a Matrox 3D DVE to the same
clip and then apply the shadow effect, you will be able to see the shadow because
the Matrox 3D DVE effect contains alpha information.
• Lock Colors Select this option to lock the colors and opacity values for the
top and bottom corners of your shadow. For example, the color and opacity
value you select for the top right corner will be used for all four corners of
the shadow.
• Top Right Corner Color Use this to set the top right corner color.
Chapter 4, Setting Up Realtime Effects with Adobe Premiere Pro
133
• Top Right Corner Opacity Sets the opacity of the top right corner. Levels
range from completely transparent (0) to opaque (100).
• Top Left Corner Color Use this to set the top left corner color.
• Top Left Corner Opacity Sets the opacity of the top left corner. Levels
range from completely transparent (0) to opaque (100).
• Bottom Left Corner Color Use this to set the bottom left corner color.
• Bottom Left Corner Opacity Sets the opacity of the bottom left corner.
Levels range from completely transparent (0) to opaque (100).
• Bottom Right Corner Color Use this to set the bottom right corner color.
• Bottom Right Corner Opacity Sets the opacity of the bottom right
corner. Levels range from completely transparent (0) to opaque (100).
¦
Note The shadow corner colors are applied based on the size of the full
screen. Therefore, corner colors of your shadow may vary depending on the
size and position of your DVE. For example, if you choose red for your
shadow’s top right corner color and scale down and position your DVE to take
up only the top right quarter of the screen, the shadow will reflect red for each
corner of the shadow even though you may have selected different colors for
all four corners.
• Shadow Softness Use this to set the softness of your shadow. The higher
the value, the softer your shadow becomes.
¦
Note Shadow Softness is applied starting from the borders of the full
screen, therefore the Shadow Softness may be less apparent based on the
size and position of your DVE.
• Blur Use this to apply blurring to your shadow.
• Camera Field of Vision Specifies the field of vision of the camera in
reference to the shadow.
• X Camera Position Moves the camera around the x axis.
• Y Camera Position Moves the camera around the y axis.

Creating a track matte effect
The Matrox track matte effect lets you superimpose one clip onto another using
an animated matte, sometimes called a traveling matte, to determine how the two
clips are composited (keyed). You can use any of the following types of clips as
your matte:
• A grayscale video or graphics clip.
• A graphics clip or graphics sequence with an alpha channel.
• Any clip to which you’ve applied an effect that provides an alpha channel,
such as a Matrox chroma key or 3D DVE.
When using a grayscale clip as your matte, areas of black in the matte create
transparent areas in your foreground clip, areas of white create opaque areas that
prevent the underlying clip from showing through, and gray areas create
semi-transparent areas in your foreground clip.
°To set up a Matrox track matte effect:
1 Place your background clip (underlying image) on the appropriate lower
track in your sequence, such as on the Video 1 track.
2 Place your matte clip directly above your background clip, such as on the
Video 2 track, and apply the Matrox Source Identifier effect to this clip.
¦
Note This effect is used only to identify which clip you’re using as the matte
for your track matte effect. If you set up another effect in the same segment
that also uses the Matrox Source Identifier effect, such as for another track
matte effect or an additional source for a Matrox cube effect, you must assign
a unique ID number to each source clip.
3 In the Effect Controls panel, click the triangle beside Matrox Source
Identifier to expand the property list, then select a unique ID number for
your matte clip from the Identify As list, as shown below:
Select a unique ID number

¡ Important Any effect applied to your matte after applying the Matrox
Source Identifier effect will be ignored. Therefore, if you want to apply an
effect such as a Matrox chroma key or apply motion to your matte using a
Matrox 3D DVE or Adobe Premiere Pro Motion effect, you must apply this
effect before applying the Matrox Source Identifier effect.

alpha channel, or a clip to which you’ve applied an effect that provides an
alpha channel, such as a Matrox chroma key.
$ Luma 0-255 Uses the full range of luminance levels in your matte to key
your foreground image. This is applicable only if your matte contains super
black and super white luminance levels.
$ Luma 16-235 Uses the standard range of luminance levels in your matte
to key your foreground image.

Using the Matrox chroma clamper effect
You can use the Matrox chroma clamper effect to ensure that when you’ve
applied effects that perform color space conversion on part of a clip, the clip’s
colors remain constant throughout. Some effects, such as Matrox
hardware-accelerated effects and Adobe Premiere Pro native effects, perform
color space conversions (YUV to RGB) that will clip RGB values to the
acceptable range of 0-255 per color component. The clipping, however, is usually
only required on clips that have very bright or highly saturated colors.
For example, if you split a clip that contains very bright or highly saturated colors
and apply a Matrox 3D DVE to one portion of the clip, you may notice minor
color differences between the two halves on your video monitor. Applying the
Matrox chroma clamper effect to the portion of the clip that does not have the 3D
DVE effect ensures that colors remain constant throughout the clip.
Selecting your speed control method
You can choose the type of speed control that’s best suited for individual clips in
your Premiere Pro projects. By default, the speed control method of each clip in
the Timeline panel is set to Frame Blend, which interpolates between the video
fields or frames, and typically works well on standard or slow-paced video and
camera pans. For fast action video you may get better results by clearing this
option.
To change the speed control method for a clip in the Timeline panel, right-click
the clip and select Frame Blend to use the speed control method that’s
recommended for standard or slow-paced video and camera pans, or clear this

Blend option.
About Adobe Premiere Pro’s fixed effects
In Adobe Premiere Pro, every clip in the Timeline panel has pre-applied fixed
effects. When you select a clip in a sequence, the fixed effects appear in the
Effect Controls panel. All fixed effects can be adjusted in the Effect Controls
panel. Adobe Premiere Pro’s fixed effects include the Motion, Opacity, and
Volume effects. Matrox RT.X2 provides realtime support for all of Premiere Pro’s
fixed effects.

Matrox RT.X2 realtime guidelines
In your Adobe Premiere Pro projects, you can use various combinations of
realtime Matrox CPU-based effects (Flex CPU effects), hardware-accelerated
effects (Flex GPU effects), and Adobe Premiere Pro fixed effects, all with
transparency.
Realtime means that the clips don’t require rendering and will play back in real
time without dropping frames (that is, there is no red indicator bar above the
segment).
The Matrox CPU-based effects are wipes, color corrections, chroma keys, luma
speed change. The Matrox hardware-accelerated effects are all the other Matrox
effects (such as page curls, 3D DVEs, surface finish effects, Premiere Pro fixed
effects and fades, etc.).
¦
Note The hardware-accelerated effects will be available only if you have a
display card that supports the Matrox hardware-accelerated effects in Adobe
Premiere Pro. For more information, see “Enabling and disabling the Matrox
hardware-accelerated effects in Adobe Premiere Pro” on page 169.
Matrox RT.X2 constantly analyzes your sequence as you work, and will identify
which segments require rendering (with a red indicator bar above the segment).
For example, once playback of the sequence has stopped, a red bar will appear
over segments of the sequence that have dropped frames. Even when your system
is idle, Matrox RT.X2 will analyze segments to determine if they require
frames when previewing. Matrox RT.X2 will always provide a preview of your
output at the best frame rate possible by analyzing the segments and dropping
frames systematically.
If you find that you have dropped frames when you export your project to tape
and those segments were not identified with a red bar, you can lower the
Realtime Indicator Threshold. For more information, see “Defining your
General settings” on page 21.
The maximum number of layers that can be played back in real time depends on
the capabilities of your system, your project’s video format, the compression
format of your clips, and the number and complexity of the effects you’ve applied
to your clips.
Matrox RT.X2 realtime guidelines

Supported graphics formats
All full-screen single-frame graphics supported by Adobe Premiere Pro are
supported in real time on Matrox RT.X2. This includes all titling formats that
Premiere Pro supports, such as Adobe Title Designer .prtl files. For details on the
supported formats, see your Adobe Premiere Pro documentation.
¦
Note Graphics rolls, crawls, and animations are not supported in real time.
Limitations
You will need to render your effects if you do any of the following:
• Apply any Field Options to a clip, such as Always Deinterlace or Flicker
Removal.
• Apply a freeze-frame effect to a clip using the Frame Hold command.
Chapter 4, Setting Up Realtime Effects with Adobe Premiere Pro

Overview
When using Video for Windows (VFW) programs to render material to an .avi
file, such as in the case of a completed video production or an animation, you can
use a Matrox codec to create a Matrox .avi file. For example, you may want to
render an animation to Matrox DV/DVCAM format so that you can record it onto
DV tape. You could also use your VFW program to render video to a Matrox .avi
file so that you can import the file as a realtime clip into your Adobe Premiere
Pro projects on Matrox RT.X2.
When rendering compositions or animations that have an alpha channel, you can
that includes the alpha-key information. This .avi file will play back in real time
on your RT.X2 system, and will be automatically keyed when you place the clip
in your Adobe Premiere Pro sequence.
The following sections explain the various settings you need to make to render
material to a Matrox .avi file using a VFW program. For details on exporting
video from a Matrox project using Adobe Premiere Pro, see “Exporting to a
Matrox .avi file” on page 36. Using Adobe Premiere Pro to export video on your
RT.X2 system lets you overcome the 2-GB .avi file limit of VFW programs.
Remarks
• When you select the Desktop editing mode for an Adobe Premiere Pro
project, Adobe Premiere Pro works like a VFW program as explained in this
chapter.
• Speed changes are not supported on Matrox VFW .avi files with alpha.
• You can’t use Adobe Premiere Pro to render effects with alpha using the
Matrox VFW “+ Alpha” codecs because Premiere Pro does not preserve the
alpha-key information during the render. Instead, you should use Adobe
After Effects to render your effects with alpha to a Matrox VFW .avi file.
• Although Matrox has tested many VFW programs, there may be certain
operational limitations when using Matrox RT.X2 with some of these
programs (as well as with untested programs).
Using VFW programs without the RT.X2
hardware
If you installed the Matrox VFW software codecs (see “Installing the Matrox
VFW software codecs on a system without the RT.X2 hardware” in your Matrox
RT.X2 Installation Manual), you can render and play back RT.X2-compatible .avi
files using your VFW program without having the RT.X2 hardware in your
computer.
Chapter 5, Using Matrox RT.X2 with Video for Windows Programs
153
¦
Note You must have the Matrox RT.X2 hardware for full support of the Matrox
MPEG-2 I-frame HD codec. The “+ Alpha” Matrox MPEG-2 I-frame codecs are
available only on a system that has RT.X2 hardware.
Before you start rendering
Before you start rendering material to a Matrox .avi file, make the following
settings in your VFW program:
• Set the appropriate frame rate for the video format to which you are
rendering. For example, if you are rendering to PAL format, set the frame
rate to 25 fps.
• Set the frame size of your rendered material to full-screen:
$ 720×480 if you are rendering to NTSC or 486p format using the
DV/DVCAM, DVCPRO, or MPEG-2 I-frame codec.
$ 720×576 if you are rendering to PAL or 576p format using the
DV/DVCAM, DVCPRO, or MPEG-2 I-frame codec.
$ 1440×1080 or 1280×720 if you are rendering to 1440×1080i/p or 720p
format using the MPEG-2 I-frame HD codec.
• To render video using the same compression format, frame size, and frame
rate as your source video but using a different video quality (data rate) or
scanning mode (interlaced or progressive), you must select the Recompress
Always option so that your video will be recompressed during the export.
• If you’ll be rendering audio, set the audio sample rate to 48 kHz and the
sample size to 16-bit (mono or stereo).
• For best results, make sure you clear your program’s Data rate limit option
for rendered material. This ensures that your .avi files will be rendered at the
particular video quality you select.
• If you’re using Adobe Premiere Pro, set the Fields for rendering to Lower
Field First for NTSC video, Upper Field First for PAL and interlaced HD
video, or No Fields (Progressive Scan) for progressive video.
¦
Note Before rendering a lot of material, check that your rendered animations
and transitions such as wipes and slides play back smoothly. If they appear
jumpy, try adjusting the field dominance or field order for your rendered material.
For example, if your transitions appear jumpy with the field dominance set to
Odd field or Field 1, try switching the setting to Even field or Field 2.
Before you start rendering
154
Selecting color space conversion options
When you render material to an .avi file using a Matrox VFW codec, you can
determine how you want the luminance levels and chroma information to be
processed during the color space conversion that’s performed during the render.
¦
Note The default settings for color space conversion provide good results for
most applications. We recommend that you change these settings only when
needed for special purposes.
°To select the color space conversion options you want:
1 Right-click My Computer, then choose Manage, and click Device
Manager.
2 Under Sound, video and game controllers, double-click Video Codecs.
3 Click Properties, then select one of the Matrox VFW codecs.
¦
Note All the available Matrox VFW codecs will be listed. You can select
Matrox VFW Software Codecs to configure all the Matrox DV, MPEG-2
I-frame SD, and legacy M-JPEG codecs.
4 Click Properties, and then Settings.
5 In the provided dialog box under Color Space Conversion, select the
options you want:
¦
Note If an option isn’t supported by the particular codec(s) you are
configuring, that option will not be available. Most options, however, are
common to all the Matrox VFW codecs. When these options are set for a
Chapter 5, Using Matrox RT.X2 with Video for Windows Programs
155
particular codec, they are also set for the other codecs that support those
options.
$ Standard Renders video using standard broadcast luminance levels.
Super black and super white luminance levels are clipped.
$ DV-compliant Renders video using luminance levelsappropriatefor DV
material. This ensures that the super white luminance levels of your video
are retained.
$ Expanded Renders video using the full range of luminance levels. Super
black and super white luminance levels are retained. You may want to use
this setting, for example, to render material on which you’ll be applying
luminance key effects.
¡ Important When rendering RGB graphics, selecting Expanded or
DV-compliant will create super black and/or white in your rendered images.
For example, if you select Expanded, all black in your RGB graphics will
become super black, and white will become super white. To render your
RGB graphics with standard black and white levels, set your luminance
range to Standard.
$ Chroma filtering and Chroma interpolation Select these options to
adjust the chroma bandwidth of RGB graphics. This improves images that
have abrupt changes between different colors, such as a blue box on a black
or white background. You should select these options for most animation
and compositing work (computer-generated material). For most video
editing programs, however, it’s best that you not select these options. If you
find that your rendered images appear to be blurred, try clearing one or both
of these options.
$ Chroma sampling for fast-motion video Select this option to help
eliminate artifacts such as jagged edges and unwanted lines at the edges of
fast-motion video (for PAL video only).
¡ Important When rendering graphics and titles, make sure that Chroma
sampling for fast-motion video is not selected, as this option can cause
jagged edges to appear in your rendered images.
6 Click OK to save your settings. Any change you make to your selected
luminance range setting (such as switching from Standard to Expanded)
will only take effect the next time you start your VFW program.
Before you start rendering
156
Rendering material to a Matrox VFW .avi file
When you render material to an .avi file, such as when you render a finished
video production or an animation, you must select the compressor (codec) you
want to create the file. The compressor determines the quality of your rendered
video. Refer to your program’s documentation for instructions on how to select a
compressor for your .avi file.
¦
Note When specifying your Export Movie settings in Adobe Premiere Pro,
you must set the File Type to Microsoft AVI on the General page, then select
the compressor you want on the Video page.
°To create a Matrox VFW .avi file:
1 Select one of the following codecs from your program’s list of available
compressors:
$ Matrox DV/DVCAM Renders video to DV or DVCAM format.
$ Matrox DVCPRO Renders video to DVCPRO format.
$ Matrox MPEG-2 I-frame Renders video to MPEG-2 intra-frame format
using the 4:2:2 Profile @ Main Level at a selected data rate (SD resolution
only).
$ Matrox MPEG-2 I-frame + Alpha Renders video to MPEG-2
intra-frame format with alpha using the 4:2:2 Profile @ Main Level at a
selected data rate (SD resolution only). This codec is available only on a
system that has the Matrox RT.X2 hardware.
$ Matrox MPEG-2 I-frame HD Renders video to MPEG-2 intra-frame
format using the 4:2:2 Profile @ High Level at a selected data rate.
$ Matrox MPEG-2 I-frame HD + Alpha Renders video to MPEG-2
intra-frame format with alpha using the 4:2:2 Profile @ High Level at a
selected data rate. This codec is available only on a system that has the
Matrox RT.X2 hardware.
¦
Note Additional Matrox codecs will be available, such as the Matrox
M-JPEG, DVCPRO HD, and uncompressed HD codecs. You can use these
codecs to create clips for use on other Matrox systems, such as Matrox
DigiSuite or Matrox Axio. For information about creating VFW clips for other
Matrox systems, see the documentation for those systems.
2 If you selected a Matrox MPEG-2 I-frame codec, click the Configure button
to configure your MPEG-2 I-frame settings. For details, see the following
section.
Chapter 5, Using Matrox RT.X2 with Video for Windows Programs
157
Configuring the Matrox MPEG-2 I-frame codecs
When you click your program’s Configure button to configure a Matrox
MPEG-2 I-frame codec (SD or HD resolution, with or without alpha), a dialog
box similar to the following appears:
¡ Important Unless you have the Matrox RT.X2 hardware, you can use the
Matrox MPEG-2 I-frame HD codec to render to a 1440×1080i/p file only. The
“+ Alpha” Matrox MPEG-2 I-frame codecs are available only on a system that
has RT.X2 hardware.
1 Drag the Data Rate slider until your desired data rate is displayed. The
higher the data rate you select, the better the video quality will be.
Depending on the capabilities of your system, however, you may not be able
to smoothly play back video at a high quality using your VFW program.
2 Beside Frame Rate, select a frame rate from the list. Make sure the frame
rate you select is appropriate for the format to which you are rendering.
¦
¦
Note The Frame Rate setting is not available if you’re rendering to
MPEG-2 I-frame SD format without alpha.
3 To apply advanced settings to your MPEG-2 I-frame file, click the
Advanced button.
Note The Advanced button will be available only on a system that has the
Matrox RT.X2 hardware, and is not available if you’re rendering to MPEG-2
I-frame SD format without alpha. The default advanced settings should
provide good results for most applications. We recommend that you change
these settings only when needed for special purposes.
4 Beside DC Precision, select the bit-depth precision of the DC intra block.
The higher the DC precision value that’s used to render your video, the more
likely that the DC content will be increased at the expense of the AC content
in the encoded stream. This may result in lowering the overall quality of the
compressed stream at a specified data rate.
Rendering material to a Matrox VFW .avi file
158
5 Under Zig Zag Order, select one of the following:
$ Regular Sets the regular (default) zig zag scanning pattern of the AC
coefficient of the DCT block as defined in the ISO/IEC 13818-2
(figure 7-2) specification documentation.
$ Alternate Sets an alternatezigzag scanning pattern of theAC coefficient
of the DCT block as defined in the ISO/IEC 13818-2 (figure 7-3)
specification documentation. Use this setting when capturing or rendering
video at a high data rate (for example, at a data rate of 100 Mb/sec or higher).
6 Under Rounding Type, select one of the following:
$ MPEG-2 Rounds the AC coefficients up to the nearest whole number
when calculating the quantization coefficient.
$ Matrox Custom Truncates the AC coefficients to the lowest whole
number when calculating the quantization coefficient. In some cases, this
setting may yield less artifacts in graphics.
7 Select the Force Frame-based DCT setting to render macroblocks as
frames rather than as fields. In some cases, graphics will yield less artifacts if
this option is selected.
8 Click OK to save your settings. The settings you selected will be used each
time you render material with your program, until you change the settings
again.

Chapter 7, Monitoring Your Matrox RT.X2 System
172
Overview
Part of your project’s workflow may involve the application of a pulldown
technique to convert your input video to your project’s video format. Pulldown
can also be applied to your output video to meet certain requirements. When a
pulldown is required in your project, Matrox RT.X2 performs either a standard
2:3 pulldown or an advanced 2:3:3:2 pulldown.
Standard 2:3 pulldown
Standard 2:3 pulldown is often used as part of the telecine process to transfer
24 fps film footage to 29.97 fps interlaced video. This pulldown method is also
used to convert any 23.98 fps progressive video to 29.97 fps interlaced video,
such as for converting 486p @ 23.98 fps video to NTSC.
In order to convert 24 fps film or 23.98 progressive video to 29.97 fps interlaced
video, additional video frames, and more specifically video fields, must be
created and added to the video sequence. For example, to convert a sequence of
four film or progressive frames, five frames of video are needed for a total of 10
video fields. Therefore, one additional video frame or two video fields must be
created. To accomplish this, the first and third frames of a four-frame film or
progressive video sequence are each converted to two video fields. The second
and fourth frames of the sequence are converted to three video fields to make up
a total of five interlaced video frames.
The following diagram demonstrates the process:
Film frames @ 24 fps or progressive frames @ 23.98 fps

D
Video fields @ 29.97 fps

a2
b1
b2
b3
c1
c2
d1
d2
d3
Frame A
Frame B
Frame C
Frame D
Frame E
Standard 2:3 pulldown is accomplished by representing the first frame of film or
progressive video (frame A) as two fields of video (fields a1 and a2), the second
frame (frame B) as three fields of video (fields b1, b2, and b3), the third frame
(frame C) as two fields (fields c1 and c2), and the fourth frame (frame D) as three
fields (fields d1, d2, and d3). This sequence repeats six times each second.
Appendix A, Understanding Standard and Advanced Pulldown
173
Performing a standard reverse pulldown (2:3 cadence) reverses the process by
converting 29.97 fps interlaced video to 23.98 fps progressive video. This is
achieved by discarding a video frame (two video fields) from the sequence. From
the diagram above, a typical standard reverse pulldown would discard fields b3
and d1. This means that video frames C and D must be read by the application to
remove the additional fields. For standard reverse pulldown that is performed on
compressed video, the application must decompress frames in order to remove
the additional fields, and then it must recompress frames to complete the
conversion.
Matrox RT.X2 implementation of standard
reverse pulldown
In order for Matrox RT.X2 to properly perform a standard reverse pulldown, the
material that is to be converted from 29.97 fps interlaced video to 23.98 fps
progressive video must have been originally acquired at 23.98 fps. When Matrox
RT.X2 performs a standard reverse 2:3 pulldown, the process identifies the A
frames of a sequence as those frames that have time code ending in 0 or 5. For
example, a frame with the time code 00:00:20:20 or 00:00:20:25 would be
considered an A frame, and therefore would be used as the first frame in a
pulldown sequence.
In the case of batch captures, when the first frame of a clip that is to be captured
might not always be an A frame, Matrox RT.X2 advances to the next instance of
an A frame in the clip to start the pulldown sequence (if it’s required). In order
for Matrox RT.X2 to perform standard reverse 2:3 pulldown accurately, the clips
must have A frames appearing at time codes 0 and 5. The clips must also be
recorded to a tape that has continuous, non-drop frame time code.
Advanced 2:3:3:2 pulldown
Advanced 2:3:3:2 pulldown was developed as an alternative to the standard
pulldown method for making frame rate conversions in DV video only. It is used
to convert 486p @ 23.98 fps video to NTSC (486i @ 29.97 fps) video. This
conversion is used when video footage is acquired by a DV camera at 23.98 fps
and recorded to DV tape with the recorder set for advanced pulldown (called
24PA or 24P Advanced mode on some devices). Advanced 2:3:3:2 pulldown
differs from standard 2:3 pulldown in that the two middle frames of the video
sequence are each converted to three video fields.

Advanced 2:3:3:2 pulldown is accomplished by representing the first frame of
progressive video (frame A) as two fields of video (fields a1 and a2), the second
frame (frame B) as three fields of video (fields b1, b2, and b3), the third frame
(frame C) as three fields (fields c1, c2, and c3), and the fourth frame (frame D) as
two fields (fields d1 and d2).
Performing an advanced reverse pulldown (2:3:3:2 cadence) reverses the process
by converting 29.97 fps interlaced video to 23.98 fps progressive video. This is
achieved by discarding a video frame (two video fields) from the sequence. From
the diagram above, a typical advanced reverse pulldown would discard video
fields b3 and c1. This means that the application can remove video frame C from
the sequence without reading the other frames.
When compared to standard reverse pulldown, advanced reverse pulldown results
in less degradation in the converted video because removing an entire frame from
the sequence leaves the remaining frames in the sequence intact, and therefore
preserves the native generation of the video.
Matrox RT.X2 implementation of advanced
reverse pulldown
The advanced reverse pulldown process is simpler than a standard reverse 2:3
pulldown because the additional frame, video frame C in the diagram above, is
tagged when the 23.98 fps progressive footage is recorded to tape. This
information is present in the DV stream and when Matrox RT.X2 performs an
advanced reverse pulldown, it reads this information to identify the additional
frame that is then removed from the sequence. Matrox RT.X2 can perform
advanced reverse pulldown on clips that have been recorded to a DV tape that has
continuous drop-frame or non-drop frame time code.

Overview
This appendix provides general information about using various Matrox RT.X2
project presets and codecs for working with different types of projects in Adobe
Premiere Pro. Workflow diagrams and descriptions are used to help explain the
specific workflow details.
Working with SD “24P” material
Matrox RT.X2 allows you to choose a Premiere Pro preset to work with SD
material originally acquired at 23.98 fps. When you select the Matrox 486p @
23.98 fps project preset, you can edit SD material as 23.98 fps progressive video
as long as the source video was originally acquired at 23.98 fps. This includes
video that was captured to tape by a DV camera capable of shooting 486p @
23.98 fps video, and Panasonic P2 video shot as 486p @ 23.98 fps and recorded
directly to disk as .mxf files. You cannot use the 486p @ 23.98 fps project preset
to capture or edit video that was originally acquired as NTSC or PAL.
Regardless of it’s origin, SD material that is acquired at 23.98 fps must undergo a
format conversion to NTSC (486i @ 29.97 fps) when it is recorded to tape, or
recorded to disk in the case of .mxf files. This means that the output from your
source device and input to Matrox RT.X2 is always NTSC. Your source device
outputs the 23.98 fps material as NTSC by applying a pulldown method when it
records the material to tape or disk.
Some DV cameras that are capable of shooting 23.98 fps progressive video have
the option of performing either a standard or advanced pulldown for recording
material to tape or disk. In order to use the video with Matrox RT.X2, we
recommend that you set your DV-1394 device to use advanced pulldown (called
24PA or 24P Advanced mode on some devices) to convert the footage to
29.97 fps interlaced video. Matrox RT.X2 will then apply an advanced reverse
pulldown method to convert the source video to 486p @ 23.98 fps for editing
clips in Adobe Premiere Pro.
¡ Important When using a Panasonic P2 camera to shoot 486p @ 23.98 fps
material for use with Matrox RT.X2, you must set the camera to Advanced
mode (486/24pA).
The output from your 486p @ 23.98 fps project on Matrox RT.X2 is always
NTSC. Matrox RT.X2 provides the option to apply either an advanced pulldown
or standard pulldown. In most cases, you would want to perform an advanced
2:3:3:2 pulldown only if your DV video requires further processing or if it is to
be archived. Otherwise, a standard 2:3 pulldown should be used when you export
your 486p @ 23.98 fps project to tape. For more information about standard 2:3
pulldown and advanced 2:3:3:2 pulldown, see Appendix A, “Understanding
Standard and Advanced Pulldown.”

Note For all Matrox RT.X2 projects, you can choose to export to an MPEG-2
file for DVD authoring or export to a web format using Matrox Media Encoder as
explained in “Exporting using Matrox Media Encoder” on page 43. For details on
other export formats, see “Exporting to a Matrox .avi file” on page 36. When
working with an SD project on RT.X2, you can also capture video directly to an
.m2v file for DVD authoring using Adobe Encore.

Working with HD projects
¦
Note Although Matrox RT.X2 SD does not support working with HD projects,
you can capture and import HDV 1080i/p clips to an SD project on RT.X2 SD as
page 182.
Matrox RT.X2 lets you capture native HDV material over the 1394 interface and
capture HD analog component input to MPEG-2 I-frame HD format. Native
HDV and MPEG-2 I-frame HD clips can be mixed in real time in the same HD
project. You can also import SD clips to your HD project and Matrox RT.X2 will
upscale the clips in real time as explained in “Mixing SD and HD clips in a
project” on page 20.
¦
Note When working with a 720p or 1440×1080p project, you can capture
native HDV material over the 1394 interface, but analog component capture is
not supported.
Matrox project presets are provided for capturing to native HDV or MPEG-2
I-frame HD format, but regardless of which preset you choose to create your
project, you can change your capture settings at any time to switch between
capturing native HDV using DV-1394 input and capturing HD analog component
video to MPEG-2 I-frame HD format. For more information about capturing to
MPEG-2 I-frame HD format, see “Using the Matrox MPEG-2 I-frame HD
codec” on page 183.
When working with a 1440×1080i/p project, you can import Sony XDCAM EX
1080i/p HQ-mode (1920×1080) and 1080i/p SP-mode (1440×1080) .mp4 files
for realtime playback. You can also choose to import Panasonic P2 .mxf files and
Sony XDCAM EX 720p .mp4 files to your 720p project for realtime playback.
When needed, Matrox RT.X2 will convert the clips to your project’s video format
timeline.
When your edits are complete you can export your project to an HDV device over
the 1394 interface (for a 1440×1080i/p project only), or export to tape using your
Matrox RT.X2’s HD analog component output. You can also choose to
downconvert the video to NTSC or PAL to record to SD tape. The format in
which you can export depends on your project’s video format as explained in
“Supported master output formats” on page 188.

Capturing HDV and SD material to edit in SD on
Matrox RT.X2
If you want to deliver in SD but take advantage of the superior image quality
offered by your HDV camera, you can capture HDV material over the 1394
interface and edit the clips in SD on Matrox RT.X2. To do this, you create a
interface. You then create an SD project and import your HDV clips.
When working in your SD project you can capture native DV clips over the 1394
interface, and capture SD clips using Matrox RT.X2’s analog component,
S-Video, and composite inputs. The SD and HDV clips can be mixed in real time
in the same SD project. The HDV clips will be downscaled to SD when you scale
the clips to your project’s frame size for realtime playback as explained in
“Mixing SD and HD clips in a project” on page 20.
When your edits are complete, you can export your project to tape as SD video
for broadcast. If you want to deliver in HD format, you import your SD project to
a 1440×1080i/p project. You can then export to HD format without having to
recapture your clips (the SD clips can be upscaled to 1440×1080i/p format for
realtime playback).
This workflow scenario is represented in the following diagram:

Capturing HDV and SD material on Matrox
RT.X2 SD
On Matrox RT.X2 SD you can take advantage of the superior image quality
offered by your HDV camera by capturing native HDV 1080i/p material over the
1394 interface in an SD project. To do this, you use Adobe Premiere Pro’s HDV
on page 35.
When working in your SD project you can also capture native DV clips over the
1394 interface, and capture SD clips using Matrox RT.X2 SD’s analog
component, S-Video, and composite inputs. The SD and HDV clips can be mixed
in real time in the same SD project. Your HDV clips will be downscaled to SD
when you scale the clips to your project’s frame size for realtime playback as
explained in “Mixing SD and HD clips in a project” on page 20. When your edits
are complete, you can export your project to tape as SD video for broadcast.
This workflow scenario is represented in the following diagram:

U¦sing the Matrox MPEG-2 I-frame HD codec
Note The Matrox MPEG-2 I-frame HD codec is not supported for capture or
export on Matrox RT.X2 SD.
The Matrox MPEG-2 I-frame HD codec allows you to control the data rate of the
video that you are capturing or exporting. At low data rates (about 50 Mb/sec) the
codec can be used to capture and export video for an offline editing project. At
high data rates (about 90 Mb/sec), the codec can be used to capture and export
high-quality video for an online editing project. The VFW MPEG-2 I-frame HD
codec allows you to render and play back MPEG-2 I-frame HD clips in VFW
applications, such as Adobe After Effects. On a system without the Matrox
RT.X2 hardware, the VFW MPEG-2 I-frame HD codec can be used to render and
play back 1440×1080i/p clips only.
MPEG-2 I-frame HD codec workflow example
for offline editing
In this workflow example, the Matrox MPEG-2 I-frame HD codec is used to
capture video clips for use in an offline editing project. The clips are captured
with Matrox RT.X2 at a data rate of 50 Mb/sec and then used to complete an
offline editing project. When the offline edit is complete, the project is trimmed,
and the offline clips are unlinked and then recaptured using the Matrox MPEG-2
I-frame HD codec at a data rate of 90 Mb/sec or higher. The online editing
project is then exported to tape for broadcast.

Using Matrox RT.X2 to edit Matrox Axio offline
H¦D projects
Note Matrox RT.X2 SD does not support Matrox Axio offline HD clips.
Matrox RT.X2 supports realtime playback of Matrox Axio offline HD clips so
that you can use your Matrox RT.X2 system as an offline editing station for
Matrox Axio offline HD projects. A Matrox Axio 720p project can be opened
directly on Matrox RT.X2 and the offline HD clips will be supported in real time.
A Matrox Axio full-size 1080i/p (1920×1080) project is not supported on Matrox
RT.X2. Therefore, to edit this offline project you’ll need to import it to a
1440×1080i/p project on Matrox RT.X2 as follows:
1 Open a new Adobe Premiere Pro project on Matrox RT.X2 by choosing
File > New > Project, and from the Available Presets list, select the
appropriate Matrox preset. For example, if you want to import an Axio 1080i
@ 29.97 fps project, select a Matrox 1440×1080i 29.97 fps preset.
2 Import your Axio 1080i/p project by choosing File > Import and browse to
your offline project’s Premiere Pro project (.prproj) file.
¥ Tip To see a list of your .prproj files in the Import dialog box, you’ll need
to select Adobe Premiere Pro Projects (.prproj) from the Files of type
list.
3 You can now edit the offline project on your Matrox RT.X2 system. When
you’ve completed the edits, you can open the project directly on Matrox
Axio, or import it to a new Matrox Axio 1080i/p project.

Glossary of terms
Use this glossary as a reference for many of
the basic terms used in this manual and
related documentation.
A
A/B roll Typically, A/B roll is an editing
technique where scenes or sounds on two
source reels (called roll A and roll B) are
played simultaneously to create dissolves,
wipes, and other effects. On nonlinear editing
systems, A/B roll refers to using two source
streams (.avi, .wav, .tga, and so on) to create
an effect.

2:3 pulldown A method used to create
additional video frames when 24 fps film
footage or 23.98 fps progressive video is
converted to 29.97 fps interlaced video, such
as NTSC. To convert a four-frame sequence
of film or progressive video, five frames of
video are required. The 2:3 pulldown
sequence accomplishes this by representing
the first frame of film or progressive video as
two fields (1 frame), the second frame as
three fields (1.5 frames), the third frame as
two fields (1 frame), and the fourth frame as
three fields (1.5 frames). See also advanced
2:3:3:2 pulldown.
advanced 2:3:3:2 pulldown A method
that is often used to convert 23.98 fps
progressive video to NTSC when the video is
acquired by a camera shooting at 23.98 fps
and recorded to DV tape. Advanced 2:3:3:2
pulldown differs from standard 2:3 pulldown
in that the two middle frames of a four-frame
sequence are each converted to three video
fields. This results in less image degradation

point. White balancing assumes that when a
white object can be made to look white, the
other color levels will also be accurate. White
balancing is used to correct improper color
levels of an image that are due to varying
lighting conditions or incorrect camera
settings. White balancing can be performed
using the Matrox color correction effect, and
is also available as a setting on most cameras.

second image could be revealed from the top
of the screen downwards until it fills the
entire screen. See also organic wipe.
X
x-y-z coordinate system A 3D
positioning system that includes a third (z)
axis running perpendicular to the horizontal
(x) and vertical (y) axes. The x-y-z coordinate
system is used in computer graphics for
creating models with height, width, and
depth, and for moving models in 3D space.
Y
Y waveform A specialized scope that
displays the luminance (Y) values of a video
signal.
Y/C video See S-Video.
YC waveform A specialized scope that
displays the combined luminance (Y) and
chrominance (C) of a video signal.
