BNC connector (labeled Pb). Attach the source’s C (chroma) connector to the
third connector (labeled Pr).
d. Composite – Attach the composite source’s connector (may require an RCA to
BNC adapter) to the second connector (labeled Y).
Note: The video broadcast standard (such as NTSC, NTSC-J or PAL) of all video sources connected
for a given session must be the same.
2. To input analog audio along with the video, connect the external audio sources to the
XLR or ¼” connectors in the Audio In group box. (We’ll discuss audio Connection Type
options a bit later, in Section 3.12.)
Note: SDI video sources with embedded audio do not need a separate analog audio connection.
3.5 GENLOCK CONNECTION
The BNC connector in the Genlock In section of TriCaster’s faceplate 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.
Genlocking is commonplace in higher-end production environments, and genlock connections
are usually found on professional video devices. 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 In connector. Next we’ll discuss the audio and video output connectors along with
relevant settings. We’ll start with video output, not only so you can view your results, but
because some aspects are best considered before even beginning a TriCaster™ session.
3.5.1 A/V OUTPUT
TriCaster™ provides separate video and audio output connector groups, and very flexible options
for display of your live and recorded video streams. Here are some of the possibilities:

Simultaneously send output to standard and/or high definition devices from HD sessions.

Simultaneously send program output to both analog and digital devices.
