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

and BG B inputs, or the scaled inputs (Layer A or B).

Please note:

• 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.

Regarding captures:

• 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.

Please note the following important prerequisites to all frame grab procedures:

• Ensure that you are familiar with the Background Input Setup Menu. In

Chapter 4, refer to the “

Background Input Setup Menu" section on page 170.

• Ensure that you are familiar with the Frame Grab Menu. In Chapter 4, refer to the

“

Frame Grab Menu" section on page 142 for details.

Note

The "Preview" capture ensures that the Program output does

not glitch when a live image is momentarily frozen and placed

in temporary memory.
