Additive Transition
source 2 will be taken to the Background A bus (without disturbing the
output of the M/E). The source 1 selection will also be immediately taken
to the Background B bus.
Look Ahead Preview
If a preview monitor is configured for Look Ahead Preview mode, the end
result of the upcoming transition can be viewed on that monitor. This lets
the operator know in advance what will occur for that next transition.
Current and Next Stack
Kayenne XL Package uses a current and next stack approach for transitions
that involve multiple elements. The current stack is the current M/E output
including any keys that are on. The next stack is defined by the current
stack and whatever next transition elements have been selected. Look
ahead preview always displays the next stack. Next transition elements
affecting stacks are Keys 1 - 4, background, and key priority.
Transitions always occur from the current stack to the next stack.
For example, if the current stack has Key 1 over Background A, and the next
stack specifies Key 2 over Background B, a mix transition will occur
between the composites (Key 1 over A to Key 2 over B). This is different
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 HD 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 is opacity changed with relation to all other keys. This means that
keyer transitioned this way are no longer considered part of the composite
and will show transparency.
Key Priority and Transitions
The four keyers on a Kayenne XL Package M/E can be assigned priorities.
This determines 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 tran-
sition.
