Let’s review Video source selection first. A drop-down menu by that name permits you to select sources for TriCaster’s principal video outputs, referred to as Output 1 - 4.  Depending on the model, as many as 3 of these primary outputs represent hardware outputs, but in all cases all four *output mixes are presented to your network as NDI sources.

* In addition, any connected hardware inputs are

on TriCaster can send other streams to its outputs as well, as discussed shortly – but the primary out streams are unique in certain respects.

Hint: Either (or both) of the a/v streams assigned to Outputs 1 and 2 are available for assignment to TriCaster’s other outputs as well, by means of the Follow 1 and Follow 2 items in the respective source menus.

Optional Source selections for primary output channels include any of the following:

    Program output
    A clean Program feed
    The ‘look ahead’ Preview
    The feed from any camera input
    Either network input source
    Media Player output
    Direct output from any M/E
    Selected Buffer content
    Follow selected M/E Program or Preview, or a Switcher color group

Audio menu options include the Master and Aux mixes, or the sound from any one of TriCaster’s audio inputs.
The video format (Resolution) for Output 1 always matches the current TriCaster session format, so its menu is locked. For Output 2, though, the Resolution menu allows you to independently configure the format.
Hint: Multiview, a versatile external display intended primarily for control room monitoring, is configured in TriCaster’s Dashboard (click the Workspace menu).

It’s worth mentioning that, for TriCasters with analog outputs, SD formats offer different Analog Out options than HD.  HD is always presented on SDI and Component connectors, but in addition to these, Composite and Y/C connections are still in common use for SD.

Composite and Y/C can even be used simultaneously, allowing three different devices to be connected to outputs in one row for SD output formats – one digital (SDI) connection along with two analog connections (see the example at right).
