If the input resolution matches the output resolution, or if the output
resolution is
larger than the input resolution, the Crop settings will be
bracketed.

to display.

This procedure enables you to capture a still frame image and assign it as the background
“type.” Please note:
•
As a recommendation, capture still frames into “temporary” memory as a setup
procedure.
•
Once still frames are captured, during live production you can easily switch the
background between Matte, a DVI input and a still frame.
„
Use the following steps to assign a captured still frame as the background “type.”
1. Because the background input is the source of the still frames which you will
capture, ensure that the background input is properly set up as a DVI source.
Refer to the “
Using the DVI Input as the Background ” section on page 94 for
setup details.
2. In Chapter 6, refer to the “ Capturing Still Frames ” section on page 117 for
instructions on capturing still frames. Up to three frames can be captured into
temporary memory:
FG_1 , FG_2 and FG_3 .
3. In the Layer Functions Section , press BG/DSK . The button will blink and the
BG/DSK Input Setup Menu will appear.
4. Scroll to the Mode line and select BG .
5. Scroll to the Type line and select the desired still frame ( FG_1 , FG_2 and FG_3 ).
Important It is highly recommended that you save still frames into
“permanent” flash memory as a setup procedure — as this is
a very time-consuming step that locks the front panel of
PresentationPRO-II.
