 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

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).

It can be very useful to link two (or more) Switcher or M/E source rows together, causing them to operate

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 89 shows the Input A
