Differences in Video Tracks with
QuickTime Movies and Avid Video
When an Avid video peripheral is connected to
your system and powered on, the following con-
ditions apply:
• All video tracks display a Video Output se-
lector, but only tracks containing Avid
video display a Video Input selector.
• You can add Avid video to an empty video
track.
• Only video tracks contain a Record Enable
button.
Record Enable Button
(Avid Video Peripherals Only)
Using Pro Tools with an Avid video peripheral,
the Record button lets you arm the main video
track for digitizing video to the Timeline. The
Record button does not display in video tracks
containing QuickTime movies, or if you do not
have an Avid video peripheral connected to
your Pro Tools system and powered on.
Locking Video Tracks
You can lock one or more video tracks to pre-
vent any video regions on those tracks from be-
ing edited.
When a video track is locked, Pro Tools restricts
all editing operations involving the track (ex-
cept for locking and unlocking video regions).
To lock a video track:
1 Select the video track or tracks you want to
lock.
2 Do one of the following:
• Start-click (Windows) or Control-click
(Mac) the name of any selected video track,
and select Locked.
– or –
• Right-click the name of any selected video
track, and select Locked.
A small lock appears in the video track, indicat-
ing it has been locked and cannot be edited.
(The lock does not appear if the Track Height of
the video track is set to Mini.)
Locking or unlocking a video track does not al-
ter the lock status of individual regions. If a re-
gion was locked before you locked the track, the
region will still be locked when you unlock the
track. However, unlocking a region in a locked
track will not allow you to edit that region. It
will behave as if the region were locked until
you unlock the track.
See the Avid Video Peripherals Guide for de-
tailed information on using the Record En-
able button and the I/O view controls with
the video track.
