Keyer Control

There are three keying modes available: Linear, Luma, and Chroma.
Linear keying mode is usually chosen for sharp images as it is usually used in professional
graphic design. For non-sharp images, please select Luma keying for basic text images.
Chroma keying mode allows you to remove the green or blue backdrop from the image and
is usually used in overlapping talent on a background image.
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, which are Key and
Fill sources. You can also select P-in-P to apply the keying effect to the PIP window.
If Luma keying is selected, the key image 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.
Please note:
If Chroma is selected, adjust the Chroma Keyer parameters in the Chroma sub menu.
