1. Key Type
This item is used to select the key type.
Luminance (ChrmOff)
(luminance key/chroma off: Self key):
The key signal is created from the luminance
component of the key fill signal.
Luminance (ChrmOn)
(luminance key/chroma on: Self key):
The key signal is created from the luminance and
chrominance components of the key fill signal.
Linear (linear key: EXT key):
The key signal is created from the luminance component
of the key source signal. This setting is used when the
key source signal and key fill signal are different.
Chroma (Chroma key: Self key):
The key signal is created using a specific hue of the key
fill signal as a reference.
Since the luminance key and chrominance key function as
self keys, the key fill signal is used as the key source signal.
When the luminance key or chrominance key has been
selected as the key type, the key signal remains unchanged
even when the key source signal is switched.
When the linear key is used, use a material with a black
background and white characters or shapes to be used
for the key combination as the key source signal. The key
combination may not be achieved neatly with materials
having colors other than black and white.
With materials with a white background and black
characters, for example, the key level can be reversed and
used by selecting ON for the key invert setting.
