Frame Store Operations (Option)
Frame Store Operations (Option)
The Frame Store function provides the ability to separately freeze,
and store, video and key signals to use in building effects. (The
Model 3000 can also store Mask signals.) In addition, the Drop
Shadow feature lets you produce a “positionable” drop shadow
when using Frame Store with a key source. Other video
enhancements include: Mosaic, Pseudo Color, Filter, Crop, and
Repositioning.
Setup
■ Clear the switcher. See “Clearing the Switcher” on page 4-4.
■ Map video and key store inputs to Aux Bus No. 4.
■ Map video store to crosspoint #2 video, and map key store to
crosspoint #2 key.
■ Optional: map key store to the video input of crosspoint #3 in
order to view the key store.
Output Routing
Video and key outputs from the frame store are routed to the
switcher crosspoint matrix and may be used as primary switcher
inputs. The video and key outputs are also routed to an output
module for use by external devices.
If the frame store is not in Freeze mode, its output is delayed by 2
fields from its input.
