DME Special Effect Operations
Lum Key: Use the input video luminance signal as the key source. This is
only available when the MVE-9000 is used.
3
When the DME being used is the MVE-9000 and 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 using the MVE-9000, the Ext Key parameter setting is only
enabled when the shaped video setting is off.
Interpolation Settings
Specifies the interpolation method for input video signals and input key
signals.
For an overview of interpolation, see “Interpolation” in Chapter 1 (Volume 1).
Selecting an interpolation method for input video signals
Use the following procedure.
1
In the DME menu, select VF6 ‘Input/Output’ and HF3 ‘Process.’
2
In the <Video Field/Frame Mode> group, select the interpolation method
for the video signal.
Adaptive Y/C: Detect changes in the luminance and chrominance
components of the video signal separately, and switch automatically
between fields and frames.
Adaptive Y: Detect changes in the luminance component of the video
signal separately, and switch automatically between fields and frames.
Field: Do interpolation in field units. This gives natural movement,
suitable for moving video.
Frame: Do interpolation in frame units. This gives higher image precision,
suitable for still pictures.
