What it is

Radiance is free, open-source video art software for live performance, including VJ work. It runs on Linux, macOS, and Windows. Performers can work with more than 150 GPU-accelerated WGSL effects and edit them live. MPV integration opens video clips, images, files, webcams, live streams, and YouTube videos. Beat detection uses incoming audio as a shared time reference for effects. Radiance can send output to one or more screens and includes a projection mapping editor. The software is released under the MIT/X11 License. YouTube videos loaded by URL require yt-dlp to be installed separately. Building from source requires Rust, Cargo, and dynamically linked libmpv. The project README notes that MIDI controller input and TCP output for LED displays are absent from the rewrite compared with version 0.6.1. Radiance is listed at free.
