Video Track Controls And Indicators - DigiDesign Pro Tools Reference Manual

If no video track is currently online, the main
video track is the video track that was last on-
line.
See "Video Online Button" on page 655 for
information on switching a video track on-
line or offline.
Multiple Video Track Playlists
Playlists provide an easy way of changing back
and forth between alternate versions of a video
track.
Playlist selector
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
For more information, see "Playlists" on
page 270.
Multiple Codecs on an Individual
Video Track
A single video track can contain video regions
compressed with different video codecs. How-
ever, once the first video file has been added to
a session, all additional video files added to the
Timeline must have the same video engine rate
as the first video file.

Video Track Controls and
Indicators
Video Track View
The video track can be viewed in Frames View or
in Blocks View, both of which display all video
region boundaries and metadata.
To set the view for the video track:
On the video track, select Frames or Blocks
■
from the View Options pop-up menu.
When switching from Blocks mode to
Frames mode during playback, the video
track will not update to displaying frames
until playback is stopped.
Frames View
In Frames View, video data is displayed as pic-
tures in the video track. These pictures are com-
puted based on the video image, and scale ac-
cording to your track zoom and height settings.
They allow you to easily find a scene or se-
quence in the video track.
Video track in Frames View
Frames do not display properly if you change
zoom settings during playback. Black frames are
drawn until playback is stopped. You should
stop playback before changing zoom settings if
you want to view frames.
If video pull-up or pull-down is enabled, frames
do not change position.
