KAYENNE — User Manual51
Keying
for the split key. Split keys normally treat the fill as unshaped since by def-
inition a split key uses a fill that is not related to the cut. The Kayenne
system gives the operator the ability to override this assumption for use
when a cut and fill are brought into the switcher from two separate sources,
such as a pair of DDRs producing related video and key signals.
Properly and Improperly Shaped Video
The following illustrations show the results of using correctly and incor-
rectly shaped video. In these examples, the video fill comes from a DPM
that provides both a key signal and a fill video signal (a linear key). The
DPM’s key signal, fill video that has been set as a shaped output, and fill
video set as unshaped is shown in
Figure 23.
