Playback of HD QuickTime
Movies
Pro Tools 7.2 with QuickTime 7.1.2 and higher
lets you import and play back QuickTime High-
Definition video files.
Setting Session Time Code Rate
for HD QuickTime Movie Import
When playing back QuickTime movies with
frame rates higher than 30 fps, Pro Tools syn-
chronizes properly only if the Time Code Rate in
the Session Setup window is set to half of the
video frame rate of the video files.
For example, to properly play back a QuickTime
HD movie at 59.94 fps, you would have to
change the session’s Time Code Rate to 29.97
frames per second.
To set the session’s Time Code Rate:
1
Choose Setup > Session.
2
In the Session Setup window, select the appro-
priate time code rate in the Time Code Rate pop-
up menu.
When playing HD video through an Avid
video peripheral or other device locked to a
standard-definition video reference (such as
a black burst generator), the display updates
at the frame rate of the video reference.
