Locking and unlocking tracks

Locking an entire track is useful for preventing changes to any clips on that track while you work on other parts of the program. A locked track is included when you preview or export the program. If you lock the target track, it is no longer the target, so source clips cannot be added to it until you unlock it and then target it. A locked track is marked by a lock icon next to the track name. If you position the pointer or a tool over a locked track, the pointer appears with a lock icon () to remind you that the track is locked. Locked tracks are dimmed in the Target menus below the Program view. If you want to lock both a video track and a track with corresponding audio, lock each track separately.

You can also lock a clip. This is useful when you don't want to lock an entire track. See Locking and unlocking clips.
