Image Processing
You can combine the background image (a still image file allocated to any of
FM1 to FM8, a freeze image written to temporary memory, or a black signal)
and the input signal.
The following types of processing are available.
Pattern key: Using the signal from a dedicated pattern generator, you can cut
out the background image and insert the signal selected on the frame
memory source bus or a color matte signal. You can adjust the size and
position of the pattern, and add modifiers.
External key: When processing an image in FM1 (3, 5, 7), you can use the
signal selected on the frame memory source bus 2 to cut out the
background image, and fill with the signal selected on the frame memory
source bus 1, or a color matte signal.
When processing an image in FM2 (4, 6, 8), you can use the signal selected
on the frame memory source bus 2 to cut out the background image, and
fill with a color matte signal (always white).
Note
An external key can only be used when the pair mode is enabled (see page
257).
MIX: Mix the background image with the signal selected on the frame memory
source bus or color matte signal. The mix ratio can be set.
NAM: Non-additive mix the background image with the signal selected on the
frame memory source bus or color matte signal.
