Keys
A key is an effect in which a part of the background image is replaced by an
image or superimposed text. The signal determining how the background is cut
out is termed “key source,” and the signal that replaces the cut-out part is
termed “key fill.” The system component responsible for processing a key is
referred to as a keyer.
Each switcher bank has eight keyers, each providing the same functionality.
On each switcher bank, you can use the following key types (methods of
processing the key source).
• Luminance key
• Linear key
• Color vector key
• Chroma key
• Wipe pattern key
• Key wipe pattern key
Key modifiers
