* An audio source may or may not be associated with a given video selection, and may or may
not be affected by
Switcher row activity – audio configuration is discussed in Chapter 16.
The Program and Preview rows are extended
with buttons labeled V1-5 . These buttons
control display of the composite output of
TriCaster’s
Virtual Inputs (Chapter 14).
The Preview row selection determines which source is queued up for
display by the next Take (cut) or Transition operation.
The Program row selection determines the primary video stream sent
to Program Output . Other imagery may be mixed with this primary
source at times – LiveMatte effects, overlays and the like, or an
incoming video source during a transition. However, it would be
reasonable to think of the Program row selection as supplying the
foundation for Program Output.
The Effects row selection provides an auxiliary video stream which
can serves in a variety of ways. For example, it could supply the
background scene for a
Program Row video stream with LiveMatte
enabled. It might be assigned to an Overlay channel (see Section
13.3), or as Input A, B or Overlay source for a Virtual Input (see
Chapter 16).
