internal test patterns.
Press {Map} to map the selected source to the selected panel button.
A Luma (Luminance) Key is one in which the hole-cutting information is derived
from the luminance (brightness) level of the key source. Please note:
~
Any source on the Key Bus can be selected as the "cut."
~
On the Keyer Menus , you can select Self , Matte , Preset Bus or Split
for the "fill" source. When Split is selected, any source on the Key Bus
other than the cut can be selected to fill the key hole.
Note When mapping Luma key sources to the control panel, use
the {Map Source/Cut} button. With Luma keys, only one
signal is needed to cut (and typically, fill) the key.
Refer to the " Keyer Functions and Modifiers
information on keying.
A Linear Key is a type of split key in which one video source is designated as the
"cut" and a second source is designated as the "fill." However, with Linear Keys ,
both sources are mapped to one button on the panel for convenience.
Note When mapping Linear key sources to the control panel, use
the {Map Source/Cut} button to map the cut signal, and the
{Map Linear Key Fill} button to map the fill signal.
