Video Section
QuickTime Playback Priority Options
Normal This is the default setting for QuickTime
Movie Playback Priority. It gives no extra prior-
ity to movie playback over other screen update
tasks such as metering, moving faders, and so
on. In most cases you should use this setting.
Medium This setting gives QuickTime movie
playback a higher priority relative to other
Pro Tools screen update tasks. Use this setting if
you experience inconsistent QuickTime movie
playback with the Normal setting.
Highest This setting gives QuickTime movie
playback highest priority. In this mode,
Pro Tools disables screen activity and requires
you to use the Spacebar to stop playback. Use
this setting if you require uninterrupted Quick-
Time movie playback.
Avid Video Errors Stop Playback
(Pro Tools HD Only)
When selected, Pro Tools automatically stops
playback of audio and video if a single frame of
video is dropped.
When not selected, Pro Tools continues play-
back of audio even if frames are dropped. In
most cases, video playback will recover within a
few frames and continue playing audio and
video in sync.

not be record-enabled. Record-enabling an au-
dio track takes other audio tracks out of record-
enabled mode.

els for tracks when they are record-enabled, al-
lowing you to maintain the same monitoring
level for tracks during recording and playback.
