The ScreenPRO-II Controller enables you to capture still frames into each ScreenPRO-II's
three internal frame stores. The "sources" of the still frames are each ScreenPRO-II's BG
A and BG B inputs, or the scaled inputs ( Layer A or B ).

Still Frame Capture Overview

Capturing Still Frames from a Background Input
Capturing Still Frames from a Layer
Saving Still Frames in Permanent Memory
Naming a Saved Still Frame
For widescreen destinations, even though you are using the frame stores of
multiple ScreenPRO-II units, you are conceptually working with only three frame
stores — each of which captures's its "slice" of the complete widescreen image.
For single screen destinations, you are working with the individual destination's
three frame stores in the normal manner.
All captures of the background ( BG A or BG B ) must occur on Preview — the
desired full screen source to capture must be visible on Preview. You will get an
error message if you attempt to capture while the source is on Program.
All captures of the layers ( LAYER A or LAYER B ) can occur on either Preview or
Program . The system only captures the active layer in its current size and
position , with no borders, and with black as the background.
Note The " Preview " capture ensures that the Program output does
not glitch when a live image is momentarily frozen and placed
in temporary memory.
Ensure that you are familiar with the Background Input Setup Menu . In
Chapter 4, refer to the " Background Input Setup Menu
Ensure that you are familiar with the Frame Grab Menu . In Chapter 4, refer to the
