Final answer:

In video editing software, locking a video track prevents changes to that track. Unlocking it allows changes. These controls are usually found on the timeline and represented by a padlock symbol.

Explanation:

In video editing software, the terms 'locking' and 'unlocking' refer to the ability to prevent or allow changes to a video track. To lock a video track, locate the track on your timeline, often shown as a row. Each software has different icons for locking, often represented by a padlock symbol. To lock it, simply click this icon, and it should show that the track is locked. Once a video track is locked, no modifications can be made to it, protecting it from accidental edits.

To unlock a video track, follow the same steps and locate the lock icon on the video track. Clicking on it again should remove the locked status, allowing edits to be made to the track once more. It is useful to lock and unlock video tracks during complex edits where multiple tracks are in use to avoid unintentional alterations.
