Inserting People onto
Backgrounds (Chroma
Keying)
You can use chroma keying to insert a person onto a
background, for example.
Chroma keying is a compositing technique that involves
specifying regions of a single color in the overlay video
(green in the following example), and inserting the
regions other than the specified regions (a person in the
following example) onto the background video. You can
also adjust the size and position of the overlay video, and
use chroma keying and PinP at the same time.
You can select from the following patterns.
