BeatVisualiser vs Radiance

BeatVisualiser makes music visualiser videos for promoting tracks on YouTube, TikTok, Shorts, and Reels. Add WAV, MP3, or FLAC audio, trim it to a chosen moment, then choose from more than 30 visual styles, including Spectrum, Waveform, Vinyl, Scope, and Split. Videos can use image or video backgrounds, custom artwork, and auto-synced lyrics. Exports are downloadable MP4s in vertical 9:16 or landscape 16:9, up to 1080p 60fps. YouTube Mode allows tracks up to 10 minutes per export; short-form exports stop at 60 seconds. The free account includes all styles, 1080p 60fps output, and no watermark, but only one export of up to 15 seconds; later exports cost one credit each. Pro is $16.99 a month, and Lifetime is $149, paid once, limited to the first 150 early supporters. The site says rendering happens locally in the browser, but Safari and Firefox lack the required rendering APIs.

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.
