3.5 GENLOCK CONNECTION
3.5.1 GENLOCK CONNECTION
The Genlock input on TriCaster’s front panel (Figure 12) is for connection of a ‘house sync’ or
reference signal (often a ‘black burst’ signal intended specifically for this purpose). Many studios
use this method to synchronize equipment in the video chain.
Figure 12
Genlocking is commonplace in higher end environments, and genlock connections are usually
found on professional gear. If your equipment allows you to do so, you
should genlock all
cameras supplying TriCaster, and TriCaster itself. To genlock TriCaster, supply the reference
signal from the ‘house sync generator’ to TriCaster’s Genlock connector.
(If you haven’t already done so, genlock all cameras connected to TriCaster inputs to the same
reference signal – see your camera manual for details.)
IMPORTANT Note: Digital audio is less forgiving in certain respects than analog. To avoid
occasional audio glitches when mixing digital audio (whether for recording or live production) you
must ensure that the timing for all digital audio sources is synchronized.
This means that for digital audio, you must do one of the following: 1) genlock all digital audio
sources and TriCaster to a house reference signal, or 2) genlock the cameras directly to the XD
output.
