Program; Preview And Source Viewports - Panasonic AV-HLC100E Operating Instructions Manual

The Program monitor could hardly be more important, hence it's prominent default location at upper-left on the Live Desktop.
FIGURE 38
Normally, the Program monitor shows what AV-HLC100 is displaying to your principal viewing audience at any
moment. Thus it displays the BKGD video layer as well as any Overlay layers displayed above it (FTB, or 'Fade
to Black', constitutes a final, completely opaque video layer that completely hides all other output).
Note: By default, Program output is sent to both SDI 1, the primary NDI output channel, labeled "MIX
1", and also the "AUX" NDI output.
Please notice that a semi-transparent red border surrounds the Program monitor. A similar red border is
shown around the viewport for any Switcher source that is currently visible on Program output. This is
referred to as 'tally' notification, which is also supplied to upstream NDI video sources that support tally,
and the hardware Tally port on AV-HLC100's backplane (see Section 6.4).
The Live Desktop also prominently displays the Look Ahead Preview monitor (labeled simply Preview) at upper-right.
The Look Ahead Preview is versatile and powerful. Instead of showing just one video source (the Preview
row selection), it displays the final result of a Cut operation performed using the Control Surface.
When BKGD is delegated, the Preview monitor will show the source selected on the Preview row on the Control Surface.
•
Overlay layers are shown on Preview when they will be displayed after the next transition.
•
• When BKGD is not delegated on the Control Surface, that layer will not change during a transition
(initiated using the Control Surface). Consequently, in this case the Preview and Program
monitors share identical backgrounds.
Hint: The background video layer is always included in any Live Desktop transition, but the Control
Surface allows you to assign the CUT, AUTO and Fader lever controls independently to the background
layer, Overlay layers, or any combination of these, using the delegate buttons beside the fader lever.
