Using The Dvk­100; Powering Up; Chroma Keying - Datavideo DVK­100 Mk II Instruction Manual

Using the DVK­100
With all devices and monitors connected correctly we can now look at how to operate the DVK­100. Firstly
we will look at Chroma Keying. In this example we are using a Green Backdrop; the principle is exactly same
if you are using a Blue Backdrop, just press Blue instead of Green.
Powering Up
Make sure the powercord is plugged into an appropriate mains socket, and that the socket is switched on.
Switch the DVK­100 on, using the On / Off switch on the rear of the unit. All the buttons on
the front panel should light up for a couple of seconds, and then the DVK­100 is ready.
Chroma Keying
Switch on your cameras, lighting, background video player and monitor/s.
Before starting please ensure that the White Balance is correctly set on your cameras.
The DVK­100 stores separate settings for CAM­1 and CAM­2, so we will start by setting up CAM­1; CAM­2
will follow the same routine.
Press the CAM­1 button on the front of the DVK­100, once pressed it should be
illuminated red.
We are using a Green Backdrop in this example; if you are using a Blue Backdrop please press the Blue button
rather than the Green button.
Press the Chroma Key button and the Green button, both should be illuminated red.
Use the Adjustment Knob to adjust the Green Keying level. You should see the effect on
the output monitor. Set the Green Keying Level to eliminate as much of the Backdrop as
possible. In the example below the backdrop has been deliberately set up poorly so that
the different adjustments can be seen
