Use the Adjustment Knob to fine tune the overlay effect. You will see that in Mode 1 the
darker areas gradually become more transparent, and in Mode 2 the lighter areas
gradually become more transparent.
If you need to reset any of the parameters to factory default, simply activate the function
you want to reset by pressing the appropriate function button, and then push the
adjustment knob in; after a second the parameter will reset to factory default.
Now we will set up the KEY-2 overlay, which will be for black areas that we want to key out.
Press the KEY-2 button on the front of the DVK-200, once pressed it should be
illuminated red.
Press the Chroma Key button and the Luma button, both should be illuminated red.
Luma Key has two modes and you will see if you press and hold the Luma button for
two seconds it flashes. If the button is constantly red it is in Mode 1, which is for
removing dark colours – If it is flashing it is in Mode 2, which is for removing light
colours. As KEY-2 is working with a black background that we want to remove, we need
Luma Mode 1, so press the Luma button so until it is illuminated constantly red.
Use the Adjustment Knob to adjust the Luma Keying level. You should see the effect on
the output monitor. Set the Luma Keying Level to eliminate as much of the black
background as possible.

You can also apply Luma Key Mode 2 to fine tune the overlay. This will start to key out the lighter areas of
the overlay.
