With this setup you can feed PowerScript’s VIDEO OUT signal to the key input of a
switcher. You can optionally connect the Program monitor to the switcher’s Video Out.
Note
Some downstream keying applications require the ability to adjust chroma, horizon-
tal, and key delays. PowerScript provides limited chroma delay adjustments. Addi-
tional delays must be done using external delay products.
