How to lock timeline tracks in Pinnacle Studio?

Pinnacle Studio offers a handy locking feature on timeline tracks. Locking the track doesn’t prevent burglars from stealing it late at night, but it does allow you to temporarily protect a track from changes as you manipulate other tracks. For example, if you want to delete the audio track that came with some video, but you don’t want to delete the video itself, follow these steps:

1. Click the track header on the left side of the timeline. A lock icon appears on the track header, and a striped gray background is applied to that track.
2. Perform edits on other tracks. For example, if you want to delete the audio track for one of your video clips, click the audio clip once to select it, and then press Delete on your keyboard. The audio portion of the clip disappears, but the video clip remains unaffected.
3. Click the track header again to unlock the track. You can undo changes (such as deleting an audio clip) in Pinnacle Studio by pressing Ctrl+Z. If you followed the steps just given, press Ctrl+Z once to relock the track, and then press Ctrl+Z again to undelete the audio clip.
