Additive Transition
Additive Transition
Additive Transition (ADD) is a special mix transition that Kayenne XL
Package supports besides normal crossfade transitions. Picture elements in
Additive Transitions are composited differently through the time of the
transition.
Figure 6. Normal and ADD Mixes
Additive transitions first fade a new picture to full intensity and then fade
the old picture out, but both full intensity pictures are mixed together to the
output during the transition. The resulting signal is clipped at white level
to prevent generating illegal video.
Additive transitions can be selected either with the ADD button in the Tran-
sition modules of the control panel or the ADD button in the side panel's M/E
Main menu.
Wipes
A wipe is a transition from one picture to another in which the edge of a
shape moves across the screen, revealing the new picture. Wipe transitions
can be applied to backgrounds, to keys, or to both simultaneously. A wipe
transition shape can be selected from a variety of patterns, and these pat-
terns can be adjusted in several ways (position, aspect ratios, edge attri-
butes, etc.).
Each Kayenne XL Package M/E has two separate transition wipe systems,
each of which can be assigned a different wipe pattern and be adjusted
independently. These systems can each use one of the two available
complex wipe pattern generators with advanced capabilities. It is also pos-
sible to combine these wipes to create extremely complicated wipe transi-
tion shapes, and generally this is used only by advanced operators. Utility
bus video signals can also be used to generate a custom pattern for a wipe
transition or other purposes.
