Program/Review Rows

The video source selections in the Switcher rows include all external inputs, including video router sources, internal sources (Media Players and Buffers), and the output from all M/Es.

The PGM (Program) row selection determines the dominant video stream of the Background (BKGD) video layer – that is the rear-most layer of the composition sent to Program output.

Other sources may be mixed above the Background layer at times as you apply LiveMatte, or as portions of an incoming Preview row video source appear during a transition.

The Preview row appears in standard Switcher mode. Selections determine which source is queued up for display in the Background layer by a subsequent (BKGD) Take or Transition operation.
