Press one of F1 through F5 to select the key type.
F1 (LUM): luminance key
F2 (LINEAR): linear key
F3 (CLEAN): clean key
F4 (CHROMA): chroma key
F5 (PATTERN): pattern key
You can now adjust the parameters for the selected key type.
Using chroma keying requires the optional BKDS-2031 Chroma Key
Board.
In addition to the BKDS-2031, using chroma keying in a D2 system
requires the optional BKDS-7133 Chroma Key Analog Component Input
Board.
If you pressed F4 or F5 in the preceding step, set the corresponding
parameters, as required.
• If you selected chroma key, make the settings in the M/E-1 CHROMA
KEY menu (see page 5-4), then return to the M/E-1 KEY 1 menu.
• If you selected pattern key, make the wipe pattern selection and
modifier settings in the M/E-1 WIPE menu (see page 4-102), then
return to the M/E-1 KEY 1 menu.
When you select a wipe pattern for the pattern key, the EDGE and
DIRECTION modifier settings in the WIPE menu become invalid. You
can make edge settings from the M/E-1 KEY 1 menu.
Adjust the parameter values.
