The Encore system enables you to capture frames into the Video Processor’s three internal
frame stores. The “sources” of the frames are each Processor’s background inputs, or any
active layer. Please note:
• For single screen and ScreenPRO-II destinations, you are working with the
individual destination’s three frame stores (
FG_1, FG_2 and FG_3) as normal.
• For widescreen destinations, even though you are using the frame stores of
multiple Processors, you are "operationally" working with only three frame stores
(
FG_1, FG_2 and FG_3) — each of which captures’s its “slice” of the complete
widescreen image.
• For “stack” systems, remember you have six “temp” frame stores available, and
your menus will change accordingly:
~ Three frame stores are available for the “bottom” stack Processor:
•
BG_FG_1, BG_FG_2 and BG_FG_3.
~ Three frame stores are available for the “top” stack Processor:
•
DSK_FG_1, DSK_FG_2 and DSK_FG_3.
Encore provides complete flexibility with regard to frame grabs:
• Temporary Frame Stores — The Encore Video Processor has three temporary
(temp) frame stores (
FG_1, FG_2 and FG_3) which function as the three sources
from which “on-air” frames originate. During operations, you can:
~ Capture (grab) frames to any “temp” frame store.
~ Assign any temp frame store to BG A, BG B or the DSK.
~ Download a frame from “permanent” storage into any temp frame store
for use on-air.
