Please note that if you select Full, the keying effect will be disabled, keeping the original
source image. For example, if you select Full

PIP, no keying effect will be applied to the
PIP image source.
After the keying mode is chosen, select Self if only one source is required for the keyer,
which is Key source. Select Split if two sources are required for the keyer (DSK), which are
Key and Fill sources. You can also select P-in-P to apply the keying effect to the PIP image
source.
If Luma keying is selected, the key image (Key Source) is configured by adjusting lift, gain and
opacity parameters.
Lift adjusts the dark/black areas of the key image. Reducing the value of Lift will make dark
areas of the key image more transparent. The background image will be showing only through
the transparent areas.
Gain adjusts the light/white areas of the key image. Increasing the value of Gain will make
light areas of the key image more solid. The background image will be showing only through
the transparent areas.
Opac adjusts the transparency of the overall foreground key image. Increasing the value of
Opacity will make the overall key image less transparent.
Invert configures the luma key color. Turning it on allows the luma key to remove the white
background and turning it off allows the luma key to remove the black background.
Please note:
If Chroma is selected, adjust the Chroma Keyer parameters in the Chroma sub menu.
If P-in-P is selected, adjust its parameters in the P-in-P sub menu.
For example, if the user selects Key 1

Chroma

P-in-P, you will then be able to apply the
chroma key effect to the P-in-P window after configuring the corresponding chroma keyer
