Layer type = Key; Mode = Luma
A Luma (Luminance) Key is one in which the hole-
cutting information is derived from the luminance
(brightness) level of the key source.
Source on the Key Bus can be selected as the “cut.”
You can select Self or Matte, Preset Bus, or Cut + Fill
for the “fill” source.
Clip: Adjust the threshold of the video that “cuts” into
the background. A hole is cut into the background
anywhere that foreground luminance is greater than
the clip level.
• Range: 0 to 100, in .01 increments
• Default: 60
Gain: Adjust the sensitivity of the key, enabling you to
change the sharpness of the keyed image. Gain only
affects the edge of the key hole, as set by the clip.
• Range: 0 to 100, in .01 increments
• Default: 90
Opacity: Adjusts the opacity of the keyed image, from
fully opaque to fully transparent.
• Range: 0 to 100, in .01 increments
• Default: 100.00
Reset: Press to return all clip, gain and opacity
settings to their default values.
