Frame Store (Option)
The primary functions of the Frame Store option are storage of
still video and key images, and creation of dropshadows behind
keys. Controls for manipulation of these functions are found on
the Frame Store Subpanel and in the Frame Store menus.
Either 2-two field pictures and keys, or 1 four-field picture and
key, can be frozen in the Frame Store.
Aux bus pair 4A/4B supplies the inputs to the frame store video
and key channels.
Video and key can be frozen either separately or simultaneously
through the use of panel controls. The system also has the ability
to layer stills in a recursive manner. The system accomplishes this
by sending the output of the frame store to the input of an M/E
for compositing with another image. The composite that is
generated can be fed back to the input of the frame store and re-
frozen.
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
