Chapter 4 Basic Operations for Image Creation
On the DME, set up the required processing to be carried out on the key
fill signal (PROCV) and key source signal (PROCK).
On the DME, make the settings so that the PROCK signal level is not
affected by a DME external key signal (so that the through output is
obtained from the keyer for the external key).
To do this, in the DME IN/OUT menu, set the front and back key modes
to "External", and set both clip and gain for the external key signal to
0.00.
For details of the operations on the DME, refer to the BZDM-7720/3720
User's Guide.
To carry out clean key processing on the return signals (DMEV and
DMEK) from the DME, press F9 (CLEAN KEY), turning it on.
Press F10 (KEY ADJUST) to select the method of adjustment of the
DME return signals. Pressing F10 toggles between PRESET and
VARIABLE.
PRESET: the clip level and gain are automatically adjusted to preset
values suitable for using the output key signal from the DIGITAL
OUTPUTS connectors on the DME.
VARIABLE: selecting this allows manual adjustment of the clip level
and gain.
Knob Parameter
1 Clip
2 Gain
Notes
• For each M/E bank, the processed key uses the following of the two
channels selected by the DME IF item in a setup menu (see page 14-
49): DME 1 for keyer 1 and DME 2 for keyer 2.
• For each M/E bank, if a DME wipe and processed key use the same
DME, the one which was selected first takes precedence.
• Even if two DME channels can be used on an M/E bank, it is not
possible to set the processed key function to ON on keyers 1 and 2
simultaneously.
• When only one DME channel can be used with the M/E banks, either of
keyers 1 and 2 can be used for a processed key, but simultaneous use on
both keyers is not possible.
