Luma Key – Lift
This setting affects dark/black areas in the key image/source feed. The key image/source feed is chosen on
the
Aux Bus Row
and should be backlit Red.
Reducing the value of Lift
will make dark areas of this
image/source more transparent. The background source/image chosen on the Program Bus Row will be
showing only through the transparent areas.
Luma Key – Gain
This setting affects light/white areas in the key image/source feed. The key image/source feed is chosen on
the
Aux Bus Row
and should be backlit Red.
Increasing the value of Gain
will make light areas of this
image/source more solid. The background source/image chosen on the Program Bus Row will be showing
only through the transparent areas.
Luma Key – Opacity
This setting affects how transparent the overall foreground key image/source is. The key image/source feed
is chosen on the
Aux Bus Row
and should be backlit Red.
Increasing the value of Opacity
will make the
overall key image less transparent.
Luma Key – Invert
This setting
reverses the effect the current Luma Key settings.
So if you can currently see the
background video through the dark areas of the key image/source feed, then switching Invert On would
make the background video show through only the light/white areas instead.
LIN Button
The LIN or Linear button sets up the keyer so it uses the luminance signals of the selected Key Source.

The SELF button sets up the keyer so it uses the luminance signals of the Key Fill. As the luminance signals
of the key fill are being used then the key source information is ignored.

or
Key2
over
Key1
if they are both
ON
or active. Use the
Top button to decide which Keyer will have
Priority
. See
Priority Button
on page 47
also.
Saving the Luma Key set up
Once you are happy with the Luma Key set up remember to
save your current user setup
(see page 30).
In this way having several Keying set ups saved to different user memory slots allows you to switch to a
previous Luma Key set up quickly.
