Keyer Control
There are three keying modes available: Linear, Luma, and Chroma.
After the keying mode is chosen, if only one source is enabled for the keyer, select the source in Key
Source. If two sources are enabled for the keyer, select the respective sources in Key and Fill Sources. You
may also select P-in-P or P-in-P Lite to apply the keying effect to the P-in-P window.
Please note:
If Luma is selected, fine tune the Luma Keyer parameters (Lift, Gain and Opac) in the Keyer option.
If Chroma is selected, fine tune the Chroma Keyer parameters in the Chroma option.
If P-in-P is selected, fine tune its parameters in the P-in-P option.
If P-in-P Lite is selected, fine tune its parameters in the P-in-P Lite option.
For example, if the user selects Key 1  Chroma  P-in-P, you will be performing chromakeying of the P-
in-P image after the relevant chroma keyer parameters are adjusted in the Chroma option.
Priority sets the key image to either the top layer or bottom layer and is only available if Key 1 or Key 2 is
selected.
The Keyer Control also allows the user to adjust lift, gain and opacity of the key image.
