Chapter 5 Basic Operations — DSK (Downstream key)
Creates key signals from luminance components or luminance and chrome components of key fill signals.
f Since the luminance key is operated as a self key, the key fill signals are used as the key source signals.
The key signals do not change even when the key source signals are switched.
Creates key signals from luminance components of key source signals. It is used when the key source signal and key fill
signal are different.
f Use source with a black background and white characters or shape to be combined by the key as the key source
signal. Source which is not black and white may not be combined clearly. Source with white background and black
characters can be used by inverting the keys with the key invert function.
Generates the key signals only from the luminance components.
Generates the key signals considering the chrome components in addition to the luminance components. This item is set
when a low luminance component color is used for key signals such as when cutting blue characters.
Cuts key fill with a key signal.
Does not cut key fill with a key signal. The part of key fill not cut out with the key signal is superimposed on the
background image.
Uses the source selected in the key fill bus column as the key source signal.
Always uses an external key. The source signal for fill is set using [Fill] in the [DSK] column.
Uses the bus signal for the key fill signal.
Uses the internal fill matte for the key fill signal. The color set in the [Fill Matte] column is used for the fill matte color.
