PROGRAM AND PREVIEW

The Program and Preview rows are extended with buttons labeled V1 to either V4 or V8,
depending on the TriCaster™ model. These buttons control display of the composite output of
TriCaster's Virtual Inputs (Chapter 11).

The Program row selection determines the dominant video stream of
the Background (BKGD) video layer – the bottom-most layer of the
composition shown on Program output.
Other sources may be mixed into the Background layer at times, as
you apply LiveMatte, or see portions of an incoming Preview row
video source during a transition.
Normally, the Preview row selection determines which source is
queued up for display in the Background layer by the next (BKGD)
Take or Transition operation.
