Section 3 — Switcher Concepts
Manipulation of the frozen image is provided through the Frame
Store Menu. Some of the operations that can be performed on the
frozen video and key images are as follows:
■ Posterization (video only)
■ Solarization (video only)
■ Positioning
■ Mosaic
■ Reverse Video
■ Color Substitution (Hue Mod, Color Mod, Hue Rotate)
■ Crop
■ Blur
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. (The Model 3000 has a mask
frame store output.)
When shadow mode is selected, panel controls provide
adjustment of the horizontal and vertical offset of the shadow and
the opacity of the shadow.
