The central band of TriCaster’s Live Desktop (the region between the upper monitoring section and the tabbed modules below) is taken up by the Main Transition controls, Local Layer Controls, and associated configuration features. Otherwise referred to as the Switcher.
SOLUTION AND WORKAROUND
The Program and Preview Rows
From top to bottom, the three Switcher rows are labeled FX, Program and Preview. Clicking a button in the Program or Preview row selects the active video source for that video layer.
- The Program row selection determines the dominant video stream of the Background (BKGD) video layer – the bottom layer of the composition on Program output.
- Normally, the Preview row selection determines what is queued up for display in the Background layer by the next (BKGD) Take or Transition operation.
The FX Row
The FX row selection supplies an auxiliary video channel which can serve in a variety of ways. For example, it can supply the background scene for a Virtual Input, or be assigned to an Overlay or DSK channel (for more information see the User Guide starting with Chapter 3.3)
Another switcher-style source selector, labeled Overlay, is situated right above the Input A row. At right Just above that you will also see local transition controls that are quite similar to those found in the Switcher’s Transition pane. Really, the Virtual Input Overlay feature matches the DSK channels found in the Switcher’s main Transition section in almost all respects. Unlike the DSKs, though, its inclusion in Virtual Input tabs make it a ‘pre-Switcher’ video layer (along with Input A and B). This means that the Overlay is applied before that composition is sent to the Switcher.
