Key Transition
Effects keys can be cut, mixed, or wiped on air in much the same
way as backgrounds. Both the effects keys and a background can
be transitioned on or off together or separately. The Downstream
Keyer has separate controls and must be transitioned separately.
1. Set up the key.
2. Select Transition
KEY 1
,
KEY 2
, and/or
BKGD
on the Keyers
Subpanel to choose which layer(s) the transition will affect.
3. If both effects keys are on air and you want to adjust which
layer is on top, select the
KEY OVER
button to toggle the
priority. You can also select the
KEY PRIORITY
button to
transition priorities.
4. Now do the transition:
a. For an effects key cut, press Transition
CUT
.
b. For an effects key mix, select
MIX
and move the
lever arm
from limit to limit or press
AUTO TRANS
.
c. For a wipe, select Transition
WIPE
, and select and adjust
the pattern as described earlier for background wipes.
Then move the
lever arm
or press
AUTO TRANS
.
d. For a DSK cut, press
DSK CUT
.
e. For a DSK mix, press
DSK MIX
.
f. When a key is on-air, the
KEY ON
indicator lights below
the appropriate keyer delegation button on the transition
sub-panel (and on the Keyer sub-panel if the on-air keyer
is delegated). The KEY OVER light will also be lighted,
showing priority.
g. Once the key is on air, you can change backgrounds
behind it: Select
BKGD A
only and do a transition.
5. To remove the key(s), select
KEY 1
and/or
KEY 2
and do
another transition. You can also cut the currently delegated
key layer on or off using the Keyer
CUT
button.
