Keyer Menus
Keyer Mask Menu
Touching the Mask subcategory button takes you to the Keyer Mask Point
of Use menu ( Figure 147 ). The Mask menu allows selection and control of
the keyer mask(s). Key masking defines areas that are protected from
keying (Inhibit) or always key (Force). The shape of the mask can originate
from a wipe pattern generator or by a selected mask signal (typically a key
fill signal delivered via the Utility bus).
The keyer delegation ( Key1 – Key4 ) is made at the top left of the screen. Once
a keyer has been delegated, choose the type of mask ( Force or Inhibit , or both)
from the data pad in the lower right corner. The example shown here is for
a Wipe Force Mask on Key 1.

Mask Sources
For either type of selected mask (Force or Inhibit) five different mask
sources are available and will appear as popup selection when you press
the
Mask Source button.
Only one mask source can be selected at a time.
