To preserve a video track and prevent accidental edits, lock it down. You can lock both audio and video tracks temporarily in an Adobe Premiere Pro timeline. Diagonal lines and padlock icons indicate locked tracks on the timeline.
- Click the lock icon to lock an individual audio or video track.
- Shift-click a lock icon to lock all audio or video tracks.
- If you need to work on one video track without affecting any others, shift-click to lock all tracks, and then click once on the desired lock to unlock just a single track.
