Differences in Video Tracks with
QuickTime Movies and Avid Video
(Pro Tools HD Only)
When an Avid video peripheral (such as the
Avid Mojo SDI) is connected to your system and
powered on, the following conditions 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 Avid video tracks contain a Record
Enable button.
Video Online Button
The Video Online button lets you select the
main video track, switch that track online or off-
line, and see at a glance by color whether a video
track is offline (grey) or online (blue).
To switch a video track online or offline:
â– Click the Video Online button of any track
that is offline (grey) to put it online (blue), mak-
ing that track the main video track.
â– Click the Video Online button of the main
video track to take it offline, and Pro Tools will
not output video.
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).
A locked video track displays a small lock to in-
dicate that the video track 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 lock 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 controls in the I/O
View.
