Configurable Program Output Mode

The last two configurable program outputs (Program E and Program F) can be set as either a standard ME output or as a custom output. Custom outputs include ME Layer Mode and Chroma Key Alpha.

• Program — the configurable program output of the ME
• ME Layer Mode — a composite alpha from the keys on the configurable program output A or B that is then available to another ME as a single alpha source. Program E uses Program A as the source for the key alphas and Program F used Program B. If the ME is in ME Layer Mode, this output is used for the composite alpha from the ME.
• Chroma Key Alpha — the key alpha that the switcher generated for the chroma key. This allows you to inspect the alpha to check for adjustments that can be made.
