A.8 MORE QUESTIONS AND ANSWERS
A.8.1 CAN I DO ANYTHING TO IMPROVE LATENCY/AUDIO SYNC?
Latency might be defined as the ‘transit time’ for an a/v stream. Each device in the video chain
introduces some limited (transmission) delay.
TriCaster’s latency is very minimal (as little as 1.5 frames), but you can take measures to keep it
to a minimum – first and foremost, by genlocking your video devices – see Section 7.1.6.
In a seemingly related matter, note that audio and video passing through TriCaster are always
synchronized. However, aspects of the physical design for IMAG (video projection) installations
can make mimic a sync issue for viewers at some locations in the auditorium. These issues are
discussed in detail in Section B.3, IMAG and Latency.
