Mask Store (Option)
The video, key, and mask outputs from the frame store are routed
to the switcher crosspoint matrix and may be used as primary
switcher inputs. The mask channel output may also be used as a
source for the mask generators.
The frame store outputs (video and key) are provided to output
modules for use by external devices.
When shadow mode is selected, panel controls provide
adjustment of the horizontal and vertical offset of the shadow and
the opacity of the shadow.
Mask Store (Option)
NOTE:
You must have the Mask Store option and Software Version 5.2
installed in order to operate this function.
The primary function of the Mask Store option is storage of masks
for masking keys. The option provides a two-field Mask Store,
allowing mask-image storage and retrieval at a 10 bit resolution.
Masks can be derived from any video source or can be drawn
with a drawing tablet.
Any video source available on the Mask Bus can be converted to
a mask via clip and gain, stored in the Mask Store, and used as a
mask by any keyer. The mask is then routed to a keyer (selected
on the Mask panel), to the Switcher crosspoint matrix for use as a
primary input, and to an output module for use by external
devices.
