rip chopper

Preview output

Sending the canvas to OBS, a browser, or a projector.

The canvas isn’t only for you. Settings → Output → Enable OBS/browser-source preview output publishes the live canvas as a local browser source, for streaming or scene capture.

Setting it up

  1. Turn on preview output in Settings.
  2. Copy the URL Settings shows you.
  3. Add it in OBS as a Browser Source.
  4. Keep rip chopper open while you preview or perform. Idle output stays black.

Output Frame Rate offers 24, 30, or 60 fps.

What it is and isn’t

This is a browser source served over localhost, not a native system camera device — apps that only accept a camera input won’t see it. Anything that takes a browser source or a captured window will.

Because the server listens on the local network for exactly this reason, the preview endpoints are the read-only ones. Every control, mutation, private media request, and progress connection needs the per-launch token that only the app itself holds.

Parity

The preview output is the same performance as the live canvas and the same performance a render produces — same clock, same envelopes, same layer order. What your audience sees on the projector is what you’re watching on the stage.
