Prism

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
