2.10 Keying
Keying inserts part of one picture into another to create a composite picture.
Keying involves three signals:
•
Background,
•
Key cut, used to specify where to cut a hole in the background, and
•
Key fill, used to fill the hole in the background.
The fill can be an incoming video signal or it can be an internally generated matte fill.
A separate key cut input signal is not necessarily required for keying. For example, a
self key (also called a video key) uses the same input signal for both key cut and key
fill.
The KayakDD system supports the following types of keys:
•
Additive Key
•
Luminance Key
•
Linear Key
•
Chroma Key
•
Preset Pattern
The KayakDD system also supports self keys and split keys.
