Next Transition Buttons
The five next transition buttons – BKGD b, BKGD a, KEY 1, KEY 2,
and KEY PRIORity – select the output signals that will change
during the next transition.
An ON indicator located beneath each next transition button is lit
when the associated signal is an active part of the M/E output in
layered mode.
NOTE:
The way the Next Transition buttons operate depends on
whether the M/E is operating in Standard Mode or in Layered Mode. The
mode of operation is set in the M/E MODE menu, described in section 3.
Next Transition Buttons (
Standard Mode
)
In Standard Mode, only the BKGD A, KEY 1, KEY 2, and KEY
PRIORity
next transition buttons and the ON and OVER indicators
below the KEY buttons are functional. (The BKGD B button and
the ON indicators below the BKGD buttons are not functional and
the LAYERED indicator is not lit.)
The transition can affect Background only, Key 1 only, Key 2 only,
or any combination of those. Multiple-layer transitions are
selected by simultaneously pressing more than one button.
Pressing BKGD A selects background video to change during the
next transition. That is, the background video output of the M/E
will change from the source selected on the A Background bus to
the source selected on the B Background bus.
At the end of the transition, the inputs selected on the back-
ground buses will interchange, or “flip-flop.” The “new video” on
the B Background bus will transfer to the A Back-ground bus, and
the “old video” on the A Background bus will transfer to the B
Background bus.
