Linear key - Quick DSK 2 Setup

Note: The DSK 1 and DSK 2 keyers can only be used for Linear or Luma keying. Chroma keying is not
supported on DSK 1 and DSK 2.
In this downstream keying example, we are supplying the SE-1200 MU with a live video signal on input 2,
this is selected on the Program and Preview rows. We have also connected a CG-350 Character Generator
(separate purchase) which is supplying separate KEY and FILL signals to inputs 3 and 4. These two CG-350
inputs will be used for Linear keying the CG- text and graphics over the live video from input 2.
Step 1: Choose the DSK Keyer channel that you wish to use. In our example, we clicked the DSK 2 button on
the AUX BUSES panel.

Step 2: We then choose the Lin or Linear and Split buttons from the KEYER CONTROLS panel to select a
linear key.
Note: If the DSK input only has one source (FILL) for keying, press Self key button. In our example the DSK
input has two sources for Fill and Key, so we select the Split button instead.
