ND-Pi

Preview and switch your live NDI and RTSP sources — followspot cameras, media servers, and anything else on the network — right at the console, over DMX from the lighting desk. No commercial converter does that. A Raspberry Pi appliance with show-grade failover.

Switch it from the lighting desk

The NDI switch no commercial converter does.

  • Preview & switch your NDI and RTSP sources — followspot cameras, media-server feeds, and anything on the network
  • Pick the source live from the lighting desk — over DMX / Art-Net / sACN
  • Show-grade failover: holds last frame on dropout, black after timeout, auto-recovers
  • Web control panel and presets — set once, recall from the desk
  • Program & multiview out to screens when you need it — bring your own Pi or buy it ready-to-run
  • Built for live production, at a fraction of broadcast NDI gear

The biggest additions this fall, in version 0.1.3.

Two networks, one box

Run NDI on a receive-only ingest network and keep control on the house network. ND-Pi works out one cable or two at boot, and you can switch from the control panel or the touch screen.

Sources come back on their own

A source that appears after startup reattaches with no restart. A swap to an absent source reads as pending, and ND-Pi says why a slot didn't reattach.

RTSP that keeps trying

An RTSP source that fails its first connection is no longer given up on. ND-Pi keeps trying until the camera is there.

The touch screen does more

Network settings and an on-screen keyboard on the box itself, so there's no laptop needed for a quick change on site.

Never updates itself

Auto-update is gone. A show device changes only when you tell it to, so the box you rehearsed on is the box you show on.

See who's driving

The panel shows which console is driving your universe and makes handoffs visible, so a surprise switch has a name on it.
