Chroma Key Masking
If there are unwanted background “holes” in the chroma key image, you can
mask these areas off. For chroma key masking you can use the main and
subsidiary masks independently or simultaneously on the selected keyer
(KEY 1 or KEY 2). The following procedures are thus the same in both D1
and D2 systems.

Press F2 or F3 to select the mask type.
F2 (KEY MASK): key masking
F3 (BKGD MASK): background masking
3
Press one of F4 (BOX) to F6 (UTIL BUS), turning it on, to select the
mask source.
F4 (BOX): rectangular mask generated by the internal box generator
F5 (WIPE): wipe pattern from the wipe generator.
When you make this selection, make the wipe pattern selection and
modifier settings in the WIPE menu (see page 4-70) and then return
to the CHROMA KEY menu.
When you select a wipe pattern for masking, the EDGE and
DIRECTION modifier settings in the WIPE menu become invalid.
F6 (UTILTY BUS): signal selected on the utility bus.
For example, to select the signal on the utility bus, press the UTIL
button in the auxiliary delegation section, and press the cross-point
button assigned to the required signal.
