
FTB (Fade to Black) constitutes a final overlay layer – one that obscures all other layers when applied.
* TriCasters 8000, 860 and 460 only
Recall, too, that the BKGD layer itself is often a composite of sub-layers:

It may include mixed video from both the Program or Preview rows.
 Selecting an M/E as source on Program or Preview can bring many more sub-layers into the BKGD
composite, including the M/E’s primary Inputs and the dedicated M/E KEY layers, which are similar
to DSK layers.
Note: Since TriCaster 8000’s M/Es are reentrant, the BKGD layer can at times reach astronomical numbers
of sub-layers in its composition all by itself!
9.3.1
SELECTING SOURCES
Video sources for PGM (Program) and PVW (Preview) rows, of course, are selected by pressing buttons on
those rows. For DSK video layers, source selection is made using a drop-down menu above the individual
DSK layer controls, located at right in the Layer Control section of the Switcher section.
Hint: Right-click camera input or Buffer buttons to select special sources from video routers or Buffers –
see Section 3.11.1 (Configuring Routers) and Section 11.4 (Buffers).
9.3.2
LINKING SWITCHER ROWS
It can be very useful to link two (or more) Switcher or M/E source rows together, causing them to operate
synchronously. The Program and Preview rows and the source rows in M/E panes show a downward
pointing triangle to the right of the row label. Click it to open a menu that lets you set up linking.
As you’d expect, rows assigned to the same color groups are linked. A selection made in any linked row
updates the selection of all other rows in the same color group to match. Thus Figure 9-4 shows the Input A
row for an M/E linked to the PGM row of the main Switcher. The “No Group” menu item removes the current
row from a group, while “Clear Group” removes all rows from the current group.
