Radiance vs Renderforest Music Visualizer

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.

Renderforest Music Visualizer creates music visualization videos in a browser for platforms such as YouTube and Facebook. Its visuals synchronize with audio of any length, using templates with abstract patterns and animations that respond to the track. You can customize a visualization with text, logos, colors, and images, and add a personal watermark. The tool has waveform and spectrum visuals and supports video export, with a listed maximum resolution of 4K. The general unlimited video-duration allowance does not cover music visualizer templates. Free and pay-per-product users can upload files up to 30 MB; subscribers can upload up to 500 MB. The Free plan costs nothing and provides HD videos with a watermark and basic features. Lite costs $9 a month and includes five HD720 template exports, 400 AI credits monthly, and 10 GB of storage. Pro costs $24 a month; Business costs $49 a month. Renderforest also offers iOS and Android apps.
