There are four Chroma Key channels which each have individual settings. The four Chroma Key are not tied
to any particular input channel, for example, Chroma Key Channel 1 could be CAM 2, or any other input
channel.
Highlight Chroma Key No and press the Enter Key, so that the value is highlighted. Use the Adjustment
Knob to set the value, and then press the ESC Key. In this example we are setting Chroma Key Channel 1.
Use the Adjustment Knob to scroll down the menu to 1. CAM SOURCE.
Using the same procedure as above, “ENTER, ADJUST, ESCAPE”, set the CAM SOURCE (Foreground)
and then scroll down to 2. BKG SOURCE and set the BKG SOURCE (Background).
In this example:
CAM SOURCE = 1 - CAM SOURCE is the studio shot that forms the foreground.
BKG SOURCE = 2 - BKG SOURCE is the background footage that will replace the keying colour.
CAM SOURCE = Foreground
BKG SOURCE = Background
Now scroll down to 3. KEY MODE, and using “ENTER, ADJUST, ESCAPE” as before, select the background
colour Green or Blue; there is a third option “LUMA”, which we will cover in
Luma Keying
.
In our example
we are using a green background.
