Locking and unlocking tracks

You can “lock” audio and subtitle tracks to prevent accidental changes to them while you are working on a movie.

To lock or unlock tracks:

  • Click the movie’s icon in the Project window.

  • In the Timeline window, click the padlock icon at the start of the tracks you want to lock or unlock.

Note: You can trim a movie even if it has locked tracks.
