Introduction to Compositing and Layering
Compositing involves stacking two or more video or graphics clips in a sequence on
multiple video tracks. You can also scale, rotate, and reposition each clip using the
controls in the Motion tab in the Viewer. The order that clips are stacked in the Timeline
determines which images appear in front of others in the Canvas. You can have up to
99 layers, or tracks, of clips in Final Cut Express HD.
Two video clips and one
graphic are layered in a
sequence.
