mask source.
When the box generator is selected, a rectangular mask is formed. You can
adjust the positions of the four sides of the box separately.
When the pattern generator is selected, you can select the pattern and apply
modifiers.
Sub mask: This uses the wipe generator signal or the signal selected on the
utility 1 bus on the M/E or PGM/PST bank, as the mask source.
When the wipe generator is selected, the patterns and the pattern modifiers
are the same as in a wipe transition.
Key Memory
The key memory function allows the keyer settings on each cross-point button
to be automatically stored, so that the next time the same cross-point button is
selected these settings are recalled automatically.
There are two modes for key memory: simple mode and full mode.
The parameters stored in each mode are as follows.
Simple mode: key type, clean mode (including the plane setting for chroma
keying), key position, key inversion, and adjustment values for the
particular key type (Clip, Gain, Density, Filter, etc. This includes color
vector key, wipe pattern key, key wipe pattern key, and chroma key.
However, in the case of a chroma key, it excludes color cancel, Y balance,
foreground CCR, window, and shadow.)
Full mode: All settings except transition (the same parameters as simple mode,
[Fine Key], key modifiers, main and sub mask settings, chroma key
detailed settings, and so on)
Key Snapshots
Key settings other than the key on/off status and the key priority can all be
instantaneously saved in a dedicated register, for recall when required. A key
snapshot comprises three values: a cross-point button number, key memory full
mode, and independent key transition, and can be called in any combination.
There are four key snapshot registers for each keyer.
For details of key snapshot operations, see “Key Snapshots” (page 299).

The blink function provides the following effects.
