Note that if the key fill video has been shaped by an external device, this
previously shaped video will not match the different key cut signal
selected for the split key. Split keys normally treat the fill as unshaped since
by definition a split key uses a fill that is not related to the cut. The Zodiak
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 25 .
