UM:Video And Audio Tracks

Video and Audio Tracks

Video and audio tracks are laid out in horizontal strips in the classic way. An empty composition defaults to one video and one audio track. The monitor will display a mixed-down view of your timeline.

A mixed-down view is the view you see as if viewing the composition from above, taking track output visibility into account.

A composition is composed of one or more media tracks (image or audio) stacked on top of each other in rows.

Each track has :

•	Per track, independent controls on the left and

•	Global track controls above these

Per track, a set of track indicators on the left :

Locking a Track

Locking a track will prevent any edit changes i.e.
