Using Color Mattes
Video input signals are not the only signals that you can
use in transitions.
You can also use the switcher’s internally generated color
matte signals. Up to four of these signals (Matte1 to
Matte4) can be assigned to the cross-point selection
buttons, allowing you to use them as backgrounds, in keys,
and as modifiers. You can change the colors of these color
matte signals.
Assigning Color Mattes to
Cross-Point Selection Buttons
Use the menu system to assign color mattes to the desired
buttons.
For details, see “Assigning video input signals to
cross-point selection buttons” (page 76).
