Frame Store (Option)
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. A two-field mask store is
also provided on the Model 3000.
Aux bus pair 4A/4B supplies the inputs to the frame store video
and key channels. The clipped mask bus (Model 3000) is the input
for the mask channel.
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.
