Multiple Video Track Playlists
(Pro Tools HD and Pro Tools LE with Complete
Production Toolkit or DV Toolkit 2, or with an
Avid Video Peripheral Only)
Playlists provide an easy way of changing back
and forth between alternate versions of a video
track.
You can perform all of the same operations with
video playlists as you can with audio playlists,
including:
• Duplicating a playlist
• Creating a playlist
• Assigning a playlist to another video track
• Renaming a playlist
• Deleting a playlist
Multiple Codecs on an Individual
Video Track
(Pro Tools HD and Pro Tools LE with Complete
Production Toolkit or DV Toolkit 2, or with an
Avid Video Peripheral Only)
A single video track can contain video regions
compressed with different video codecs of the
same type of video. For example, you can add
QuickTime files that were compressed using
multiple codecs to the same video track.
However, once the first video file has been
added to a session, all additional video files
added to the Timeline must have the same video
frame rate as the first video file.
Main Video Track
The main video track is the video track that is
currently online, and will be played back with
any audio in the session.
When the main video track is offline, you can
play back the audio in your session without
playing back the video. When the video is of-
fline, the Video Online button changes to gray
so you can tell at a glance whether your video is
offline or simply playing black fill.
If no video track is currently online, the main
video track is the video track that was last on-
line.
To select the main video track:
„ Click the Video Online button of any track
that is offline (gray) to put it online (blue), mak-
ing that track the main video track.
