Prism is a beginner-friendly live visuals app for triggering clips and compositing overlays in real time. Made for school events, small concerts, and sports, it combines instant clip triggering with hands-on control of the program output.
Instead of a fixed grid, clips live on a node-based canvas with groups, transform contexts, and audio routing — click to trigger, with no scenes or playlists to manage.
Features:
- Node-based clip canvas with groups, transform contexts, audio routing, and a VJ hotkey grid
- Many source types: video, images, slideshows, webcams, screen and window capture, GLSL shaders, HTML/QML overlays, text, Lua scripts, NDI inputs, and phone cameras over WebRTC
- Live A/B deck mixing with a crossfader and per-deck speed control
- Per-clip trim, crop, transform, and composited text/image overlay editing
- Audio spectrum analysis driving shader inputs, plus master audio routing
- Reusable asset library with drag-and-drop onto the clip canvas
- Program output hub: mirror windows, optional NDI output, virtual-camera output, and program video/audio recording
- Panic controls: instant blackout, freeze-frame hold, and stay-tuned overlay
- OBS WebSocket integration and network remote control
- Session save and load with autosave and smart asset relinking
