Shaped Key
An additive key where the Key Alpha cuts a hole based
on the monochrome value of the alpha. Shades of gray
are translated into either white or black, giving the key
a hard edge. Shaped Key alphas are sometimes used
with Character Generators to cut very precise holes for
the fill.
Split Key
A Split key allows you to assign a different alpha
source for a key than the fill/alpha associations that are
set up during configuration or to use a separate alpha
source for a Self key.
Tally
An indicator which illuminates when the associated
button, or control, is selected or is on-air.
Unshaped Key
A multiplicative key where the Key Alpha cuts a hole
based on the gradient values of the alpha. Shades of
gray are translated into transparency levels, giving
the key a soft edge. Unshaped Key alphas can also be
considered true linear alphas. Key alphas are set to
unshaped by default.
