DME Special Effect Operations
2
In the <Front Key> group or <Back Key> group respectively, press one of
the following, turning it on.
Ext Key: Use the key signal sent from the switcher as the key source.
Int Key: Use the full-size DME internal key signal as the key source.
Lum Key: Use the input video luminance signal as the key source.

When Ext Key or Lum Key is selected in step 2, set the following
parameters.
Notes
• The Ext Key and Lum Key in the <Front Key> group share clip and gain
settings. Similarly, Ext Key and Lum Key in the <Back Key> group also
share clip and gain settings.
• When the first channel is selected, it is not possible to set the Ext Key
parameter.
Interpolation Settings
Specifies the methods used for interpolation processing of input video signals
and input key signals.
For input video signals, you can select from the following four methods.
• Detect changes in the luminance and chrominance signals separately, and
switch automatically between fields and frames. You can select the degree of
change detection.
• Detect changes in the luminance signal separately, and switch automatically
between fields and frames. You can select the degree of change detection.
• Do interpolation in field units.
• Do interpolation in frame units.
For input key signals, you can select from the following three methods.
• Detect changes in the luminance signal separately, and switch automatically
between fields and frames. You can select the degree of change detection.
• Do interpolation in field units.
• Do interpolation in frame units.
You can also select the number of pixels used in interpolation processing, and
select the method used to show the picture reduced or expanded.
