Preset Pattern

A preset pattern uses a wipe pattern generator, rather than an incoming key
cut signal to define the hole cut in the background (

Figure 62

). Key clip and

gain controls are not available for a preset pattern, but controls over the
location, size, border, opacity, and edge softness are available.

Split Key

A split key uses an alternative key cut signal for keying. On the Kalypso
system, a key split is performed by selecting the desired key fill signal, then
selecting an alternative signal to be used as the key cut (

Figure 63

).

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
