The Vizrt TriCaster device controls Vizrt TriCaster live production systems (formerly NewTek) over their HTTP control interface.

Connection

The agent connects to the TriCaster over the network. Provide the switcher’s host, and if needed adjust the port (default 80), the user name and password (both default to admin — change them on your switcher for security), and the status poll interval.
The TriCaster must have a live session running (not just be powered on) for automation commands to work.

Commands

The TriCaster device supports a broad set of live-production operations, including:
  • Set the program and preview source by name, and cut or auto-transition — with a selectable transition type and speed
  • Control M/E buses and downstream keyers (transition, or force on/off air)
  • Start and stop recording and streaming, and grab a still of the program output
  • Control media players (DDRs, graphics, stills, and titles) — play, stop, next, previous, and mark in/out
  • Run macros by name
  • Set audio volume and mute per source, and route outputs (mix/aux) to a source
  • Recall and save M/E memories
  • Push rundown data into on-air title templates
  • Send a raw switcher shortcut for operations not listed above

State and triggers

The device reports its connection state and raises triggers your rules can react to, including:
  • Connection changes
  • A source going on or off air (tally)
  • Program and preview source changes
  • Recording and streaming state changes
Trigger data such as the source name and on-air status is available for use in rule actions.
