The Output Configuration panel (Figure 66) has several tabbed panes. The first two are labeled Output A
and B, and contain controls discussed momentarily. The Genlock & Failsafe tab is home to important
video timing calibration controls. We’ll review it shortly, as well.)
The video format sent to 3Play’s video outputs (SDI or NDI) always matches the session format, which you
choose in the Startup screen when first creating the session.
Note: On 3Play’s rear panel, the VIDEO OUT group connectors labeled 1-4 carry channels A, B, and two
instances of Aux respectively.
NAME
The Name field is editable, allowing you to assign a custom name to each output. The name you supply
will appear in the Channel Info pane (Section 2.5) in the Desktop monitoring section and Multiview display.
AUDIO VOLUME
The Audio Volume slider in the Output Configuration panel lets you independently modulate the raw
source sound level before passing it to the corresponding audio output.
Note: You’ll recall that the audio and video connectors for Channel A are labeled “1” in the output
connector groups on 3Play’s backplane, while Channel B connectors are identified by the number “2”.
ENABLE REVERSE KEY
We’ll discuss this feature in the context of 3Play’s DSK (Downstream Keyer) features in Chapter 15.
7.1.2 GENLOCK & FAILSAFE
The Genlock feature allows 3Play to ‘lock’ its video output to timing derived from an external reference
signal (house sync, such as ‘black burst’) supplied to its genlock input connector.
