CK Auto : This function automatically calculates the best Hue & Luma values for the current
Keyer source. After applying the CK Auto effect, the result can be fine-tuned by adjusting
the Luma and Hue values.
Hue : This parameter adjusts the color of the chroma key. A typical green screen value will
be around 120. Blue screen value will be around 240.
Luma : This parameter adjusts the luma value of the chroma key
K Range (Key Range): Key Acceptance sets the range of hues or colors (0 – 360 degrees) that
closely match the background color to be keyed. The user can start with a value of 120
degrees and this value can be fine-tuned up or down depending on the setup of the green
or blue screen studio.
K Fgnd (Key Foreground): Key Foreground adjusts the performance of the chroma key in
light or white areas. Apply more Key Foreground if the light areas are becoming too
transparent.
K Bgnd (Key Background): Key Background adjusts the performance of the chroma key in
dark or black areas. Apply more Key Background if the dark areas are becoming too
transparent.
Hi-Light : Hi-light boosts the foreground key in high luminance area.
Lo-Light : Lo-light boosts the foreground key in low luminance area.
Bg-Supp: Background Suppress removes the Luma (Brightness) of the background from the
final image. Bg-Supp turns ON/OFF background suppression.
