Compose

The Element Compose is used to combine two audio- or video elements in a way that both are audible or visible at the same time. I.e. a (partly transparent) video asset like a green screen video can be played 'on top' of a background video. The same can be done for a logo or lower third. Something else often done is adding an audio asset to a video without (or with as a matter of fact) audio.
