Keyer Areas
One of the two key OVER indicators on the associated transition
subpanel is always on, indicating the priority of the Keyers 1 and
2. The indicator is on regardless of the on-air status of either keyer.
The INVert toggle button inverts the polarity of the key source.
Inversion is applied to the incoming key source before key
processing is applied. INVert operates in all keyers in layered
mode.
The SHOW KEY button is used for viewing the key signal on a
particular keyer. This button does not affect the on-air video.
When held down, the switched preview bus output shows the key
signal from the keyer currently delegated to the keyer subpanel.
The key signal displayed is the key after clipping, masking, and
chroma trapping have taken place.
The SHOW KEY button does not affect the program output of the
M/E and operates in all keyers in layered mode.
Borderline Controls
The buttons at the top of the keyer
subpanel control the Borderline option.
The
NORMal, BORDer, SHadow, EXtrude,
and OUTLINE buttons are
interlocked; only one button can be active at a time.
NOTE:
The background keyers (layered mode) do not have Borderline
capability.
Border, Shadow, and Extrude modes operate with video or matte
filled keys. The Borderline matte is separate from the fill matte
and has its own delegate button in the matte subpanel.
The Borderline matte is adjusted in the matte subpanel after
selecting K1 BORD or k2 BORD, as appropriate, with the MATTE
SELect
delegation button.
The NORMal button turns Borderline off.
