Preset Pattern
A preset pattern uses a wipe pattern generator, rather than an incoming key

size, border, opacity, and edge softness are available.

split key uses a fill that is not related to the cut; that means the normal mode
for keying is Luminance or Linear Key Mode.

that provides both a key signal and a fill video signal (a linear key). The
