Keying Overview
Video keyers allow you to insert additional video into the video back-
ground. They are commonly used to insert station logos, or text from char-
acter generators, or picture-in-picture feeds from still stores, production
switchers, or digital video effects equipment.
Keys can be configured from an external source or be a self-key. They can
be filled with matte if desired and the matte parameters adjusted with con-
trols on the Keyer Control subpanel. Linear or luminance type keys can
also be defined.
