Now we will set up the CAM-2 overlay, which has a black area we want to key out.

Press the CAM-1 button on the front of the DVK-100, 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 CAM-2 has a black background that we want to remove, we need Luma

Mode 1, so press the Luma button so that 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.

Overlay with Black Matte Area Overlay after Luma Keying Level

Adjustment

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.

Press and hold in the Luma button for two seconds, until it starts flashing red.

Use the Adjustment Knob to adjust the Luma Keying level. You should see the effect on the

output monitor. The lighter areas of the overlay will start to disappear. This is really a fine tune

adjustment, if you go too far everything will appear.

Now press the Density (Level) button. The Chroma Key and Density buttons should both be

illuminated red. When using Luma Key, the Density button has two modes and you will see if

you press and hold the Density button for two seconds it flashes. If the button is constantly red

it is in Mode 1, which adjusts the density of dark colours  If it is flashing it is in Mode 2, which

adjusts the density of light colours. You can use both Modes 1 and 2 to fine tune the overlay

effect.
