External Inputs

Integrate video and media applications with Spectralite for reactive lighting

External Inputs

Spectralite can react to external video and media applications through NDI (Network Device Interface) video streams. This enables your lighting to respond to visual content from VJ software, live video, and other sources.

What is NDI?

NDI is a free protocol that transmits high-quality, low-latency video over standard networks. It's widely supported by professional video and media applications, making it ideal for connecting visual content to lighting control.

Supported Workflows

How It Works

  1. External Application outputs video via NDI
  2. Spectralite receives the NDI stream
  3. Effect Nodes sample pixel data from the video
  4. Lighting Output responds to the video content

This creates reactive lighting that follows your visual content - colors, brightness, and patterns all derived from the video stream.

Use Cases

VJ Performance

Sync your lighting rig with live VJ visuals, creating a unified audiovisual experience.

Live Video

React lighting to live camera feeds, player footage, or broadcast content.

Generative Art

Connect generative visual systems like TouchDesigner or Processing to create dynamic lighting experiences.

Content Playback

Use video content as a lighting control source for pre-programmed shows.

Getting Started

If you're new to NDI with Spectralite:

  1. Start with Sending NDI Video to Lights for the basic workflow
  2. Find your specific application guide for setup details
  3. Experiment with different effect nodes to sample the video

Network Considerations

For reliable NDI streaming:

  • Wired Ethernet recommended for best performance
  • Gigabit network for HD video streams
  • Same subnet for automatic NDI discovery
  • Low latency for real-time lighting response
  • Node Editor - Create effects that sample NDI streams
  • Effects - Learn about available effect nodes
