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).
