Outputs
An output is a renderable URL. Point any broadcast tool (vMix, OBS, TriCaster, Wirecast, etc.) at the URL as a browser source and the output's graphics appear over your feed with a transparent background.
What an output has
- A name — what the team calls it ("Main cam overlay").
- A slug — the piece of the URL that identifies it.
- Width and height — the rendering resolution.
- An optional description.
The public URL looks like: https://your-domain/output/<slug>.
Resolution
Match the output resolution to the capture resolution on the broadcast tool. A 1080p browser source capturing a 720p output stretches; the reverse looks crisp but wastes bandwidth. Mismatches are the most common cause of "the graphics look wrong".
Transparent background
Every output renders on a transparent background. The broadcast tool must be configured to use transparency on its browser source — otherwise the output appears on a solid (usually black) background.
One output, many productions
A single output can be driven by different productions at different times — but only one at a time per output. The last production to take something on the output wins; other productions' states are not affected.
