Chapter 51: Working with Video in Pro Tools 1145
Windows Media Video (VC-1
AP Codec) Support in
Pro Tools
(Windows Only)
Pro Tools supports the import and playback of
Windows Media video files created using the
VC-1 Advanced Profile codec. See your Win-
dows documentation for detailed information
about Windows Media video.
Windows Media Video File
Caveats
The following limitations apply to Windows
Media video in Pro Tools.
Pro Tools cannot open Windows Media video
files that require Windows Media File Digital
Rights Management (DRM) passwords to
view.
High-resolution Windows Media video files
play back accurately at normal speed on the
Windows desktop or an external monitor
with a qualified DirectShow output device.
However, due to processing requirements for
VC-1 decompression, Avid cannot guarantee
accurate playback of video frames when per-
forming other transport commands (such as
scrubbing, looping, and off-speed play).
Pro Tools does not support Windows Media
playback via Avid video peripherals.
Before Starting Your Project
Before you start any project that requires work-
ing with video, consider the following:
Frame Rate Before receiving video, find out the
frame rate. Use this frame rate when setting the
frame rate of your Pro Tools sessions and when
capturing video.
Creator Application and Codec Before receiving
video as media files, find out the application
and codec used to create those files. Then con-
firm that you can play those files in Pro Tools. It
is always a good idea to get a sample file in ad-
vance.
QuickTime Movie Time Code Burn-in Before re-
ceiving QuickTime movies, request the time
code display to be “burned in” (superimposed) if
possible. This ensures that Pro Tools places the
file at the correct time code location in the
Timeline.
Sufficient Space on Video Drives Ensure suffi-
cient space is available on separate dedicated
video-only drives. Video files take up signifi-
cantly more space and bandwidth than audio,
and must be kept on separate drives from audio
files to prevent performance problems.
Separate Video-Only and Audio-Only Drives For
best results, always use separate video-only and
audio-only drives. For complete information on
hard drive requirements, visit www.avid.com.
Though not prohibited, editing Windows
Media video or adding multiple clips to the
Timeline can lead to irregular video output
performance.
