Keying Overview

Keying allows you to insert portions of one scene into another. Keys appear as overlays over the background image.

The switcher supports three key types:

•Auto-Select Key — Key alpha (transparency) is provided on one input and key fill video is provided on a second input (character generators and graphics systems typically provide fill and alpha on separate channels).

•Self Key — Key transparency is derived from the luminance of the key fill video (this key type is created when you do not specify an input for the key alpha channel).

•Chroma Key — A user defined color hue is selected for transparency (such as blue or green-screen applications).
