Layer type = Key; Mode = Chroma
A Chroma (Chrominance) Key is one in which the
hole-cutting information is derived from a color in the
key source.
After selecting a Hue color to key out, it may be
necessary to make additional adjustments to improve
the look of the overall compositing effect.
Chroma Clip: This is an angle, centered around the
Hue color. Any color inside this angle is fully keyed
out.
• Range: 0 to 100
• Default: 10
Ramp: This is an angle, also centered around the
Hue color. It must be equal to or larger than the
Chroma Clip angle. Inside the Chroma Ramp angle,
the colors keyed out ramp linearly the closer the
foreground color approaches the Chroma Clip angle.
Outside the Chroma Ramp angle, the foreground
colors are not suppressed.
• Range:0 to 100
• Default: 90
Opacity: This allows the key source to become
increasingly transparent with respect to the
background source.
• Range: 0 to 100
• Default: 100
Hue: This field selects the color to be removed or
keyed out of the input. While this can be manually
adjusted, the "PICK HUE" feature also changes this
number.
• Range: 0 to 100
• Default: 0
Spill: Spill removes unwanted “ key ” color, which is
generally a result of reflection from the (green or blue
screen) background, on the foreground object.
• Range: 0 to 100
• Default: 0
Shadow: This allows shadows to be preserved or
removed in the foreground image (opposite of
Highlight).
• Range: 0 to 100
• Default: 0
Highlight: This allows highlights to be preserved or
removed in the foreground image (opposite of
Shadow).
• Range: 0 to 100
• Default: 0
Saturation Clip: This defines the threshold along the
Saturation axis where keying begins.
Below the clip threshold, the colors are not keyed out.
Above the clip threshold, the colors follow the results
of Chroma Clip and Gain, but they depend on the
Saturation Gain setting as this creates a linear key
color strength ramp in the key area.
