Use the following steps to capture a frame from a background input:
1. Ensure that the background (or DSK) input from which you want to capture is
properly set up as an Analog or DVI input. In Chapter 6, refer to the
"
Background Setup " and " DSK Setup " sections for instructions.
2. Ensure that BG A , BG B or the DSK are not on Program. If they are, you will get
a pop-up prompt. Transition these layers off Program in the normal manner.
3. In the Layer Control Section , select the background (or DSK) from which you
want to capture. The button blinks, the source appears on Preview, and the
selected setup menu appears.
4. In the Layer Functions Section , press FRAME GRAB to display the Frame
Grab Menu .
5. On the Destination line, select the destination for which you want to capture.
~
If multiple destinations are active, select the desired destination.
~
If a single destination is active, selections cannot be made.
6. On the ID line, select the IDs of the Processor(s) for which you want to capture.
~
For single screen destinations, ID selections cannot be made.
~
For wide screen destinations only, select All to capture across all
Processors, or select the ID of an individual processor.
7. On the Frame Number line, select the temporary frame store into which the frame
will be captured ( FG_1 , FG_2 or FG_3 ). Remember that for "stack" systems:
~
Background frames are captured into the "bottom" stack Processor:
BG_FG_1 , BG_FG_2 or BG_FG_3 .
~
DSK frames are captured into the "top" stack Processor: DSK_FG_1 ,
DSK_FG_2 and DSK_FG_3 .
8. Press { CAPTURE }. Once pressed, the screen will indicate that the frame is being
captured. A pop-up message confirms the procedure. In the Name field, the
captured frame is listed as UNSAVED .
9. Repeat the procedure to capture additional frames from a background (or DSK)
input. Remember that you can always overwrite the selected frame store.
Please note:
•
The captured frame(s) can now be assigned as the input “type” for BG A , BG B or
the DSK . In Chapter 6, refer to the following sections for instructions:
~
" Background Setup ," page 269.
~
" DSK Setup ," page 274.
•
Captured frames reside in temporary memory. If the system is powered down or
reset, the frames will be lost. To save frames in permanent memory, refer to the
"
Saving Frames in Permanent Memory " section on page 336.
•
Only "saved" frames can be named.
Note In the case of an individual ID selection, the frame will be
grabbed only for that Processor — leaving the other "wide
screen" portions of that frame store available.
