NDI Input

Enable NDI video input and use it in effects

NDI Input

Open from Edit > Inputs > NDI. NDI (Network Device Interface) lets Spectralite consume live video from any NDI-capable application on the same network: Resolume, TouchDesigner, VDMX, OBS, and others.

Controls

NDI input enabled: turns the NDI receiver on. Keep it off when not using NDI, to avoid background network traffic.

Auto-discover sources: scans the local network for available NDI senders and makes them available to the NDI Input node and the built-in NDI Input layer effect. Leave this on unless you have a reason not to.

The dialog has no per-source picker. Selection happens where the source is used: the NDI Input node in the Node Editor picks up the first available source by default, and the built-in NDI Input layer effect does the same.

Using NDI

Two ways to bring NDI video into a show:

  • Built-in layer. Add a new layer in the Timeline (+ Add new layer) and choose the built-in NDI Input effect. That layer samples video color directly onto the mapped fixtures.
  • NDI Input node. For custom effects, open the Node Editor and drop in an NDI Input node. It takes a position input and outputs a color. Wire it anywhere color would otherwise come from.

See Sending NDI Video to Lights for the end-to-end workflow.

Troubleshooting

No NDI source visible. Confirm both devices are on the same subnet, that Auto-discover is on, and that the sending application is transmitting. NDI uses mDNS for discovery, so firewalls that block multicast will prevent discovery.

Dropped frames. NDI is bandwidth-hungry. For HD streams, prefer a wired gigabit path between sender and receiver. Lowering the sending resolution is usually the quickest fix.
