ADOBE PREMIERE PRO CS3 105 User Guide Lock and unlock tracks Locking an entire track is useful for preventing changes to any clips on that track while you work on other parts of the sequence. In the Timeline panel, a pattern of slashes appears over a locked track. Although clips in a locked track cannot be modified in any way, they are included when you preview or export the sequence. If you want to lock both a video track and a track with corresponding audio, lock each track separately. When you lock a target track, it is no longer the target; source clips cannot be added to the track until you unlock it and target it again. You can lock a track to prevent it from shifting when you perform insert edits. ❖ Click to display the Lock icon next to the track name.
