# Track Basics

The timeline supports multiple video and audio tracks. Having multiple video tracks on the same timeline is useful for quick access to different versions of your work.

Video tracks can have multiple layers. For information on working with layers, see NO LABEL .

For information on audio tracks, see Working with Audio in the Timeline.
