12.3 OVERLAY
Figure 138
The Overlay panel is the final component of the central Switcher section of the Live Desktop for
us to discuss. You’ll find it at the right-hand end of the Switcher panel (beneath the Program
Output monitor). This placement is quite appropriate, as the two Overlay channels configured
and controlled in this section represent a final opportunity for you to superimpose imagery on
the video stream prior to output.
12.3.1 TWO CHANNELS
This group provides individual (or optionally, linked) control over two overlay (downstream
keyer, a.k.a. “DSK”) channels designated
Overlay 1 and Overlay 2 . Imagery displayed in Overlay
2 appears ‘in front of’ Overlay 1 on Program Output – that is, closest to the viewer.
12.3.2 OVERLAY SOURCE
Figure 139
The Source button at the top of each Overlay section (Figure 139) identifies the current source
for that overlay channel. The default source for Overlay 1 is “Titles”, while for Overlay 2 it is
“Effects”. Clicking the Source button opens an input selector button row (Figure 140).
