Keying
from mixing Key 1 off, Key 2 on, and mixing between A and B at the same
time, which would cause the keys to go transparent over their background
during the transition.
On the Kayak system, opacity is retained throughout the transition, so
midway through this example Key 1 remains fully keyed over Background
A, and Key 2 is fully keyed over Background B. The transition occurs
between these two fully keyed composites.
If multiple keys are faded in or out using the separate Mix button each keyer
has it’s opacity changed with relation to all other keys. This means that
keyer transitioned this way or no longer considered part of the composite
and will show transparency.
Key Priority and Transitions
The four keyers on a Kayak M/E can be assigned priorities. This deter-
mines the layering of the keys. The highest priority key appears on top,
while keyers with lower priority may be partially or fully hidden behind
those with higher key priorities. The backgrounds always have the lowest
priority. Changes in key priority can be included as a part of a transition.
Like any other transition, the current stack will transition to the key priority
of the next stack. For example, suppose the current stack has Keys 1, 2, and
3 in that key priority order over Background A, and the next stack specifies
key priority order 3, 2, 1. A mix transition will occur between the 1, 2, 3
composite order to the 3, 2, 1 composite order. All three keys will remain
fully keyed over the background, and will mix to their new key priority
order.
Half M/E and DSK Option
The Half M/E and DSK option is available that adds an additional M/E
with cuts and mixes on backgrounds and keyers. The output of this Half
M/E can be re-entered into any other M/E, and/or be assigned to an Aux
output. The Half M/E is controlled by delegating any switcher bank with
a single button press.
DSK capabilities that adds four extra keyers is also included with this
option. Half M/E and DSK functionality cannot be used simultaneously,
however.
