Keyer Subpanels
Pressing the OUTLINE button produces an outline of the key
signal. The border width is adjustable to one, two, or three lines.
In Outline mode, there is no fill video or fill matte; only the
background video and outline border matte are output. As a
result, the VIDEO FILL and MATTE FILL buttons have no effect
when OUTLINE is active.
The BORDERLINE SIZE/POS knob adjusts the width of all
Borderline borders. The control also moves the shadow or
extruded shadow either down to the left or down to the right.
The BORDERLINE OPACITY knob adjusts the transparency of the
Borderline borders.
Auto Preview Operation
In normal operation, the Switched Preview output of the system
may be set to monitor any of the M/E preview outputs, DSK
preview output, or preview primary bus.
The Auto Preview feature is activated by pressing one of the keyer
delegate buttons (KEY 1, KEY 2, BKGD B, or BKGD A) for 1/2
second or longer. When Auto Preview is active, the delegated key
is inserted over the M/E preview or DSK preview output on the
Switched Preview bus so that you may preview the key setup.
Holding down the keyer delegate button or turning the CLIP
and/or GAIN controls prolongs the Auto Preview mode. The
preview returns to normal after the delegate button is no longer
held down and there is no activity on the CLIP or GAIN controls.
