Drop a song. Drop a library. Get a music video.
Sainted Word Records is a browser-based audio-reactive video engine. The engine reads your song, scores every clip in your library by how it actually moves, and composes a layered real-time video that breathes with the music. Export as MP4. Local-first. MIT-licensed. No account.
How it works · 3 steps
From audio file to MP4 in one tab.
Drop a song and a library of clips.
MP3, WAV, M4A. Drag any number of MP4 / WebM / GIF / PNG / JPG files onto the page. The engine scores each by motion, luma, and hue — not by filename.
Press play. The audio drives the visuals.
Web Audio analyser extracts BPM, key, beats, and chromagram in real time. The 6 layers mix, blend, and pulse with the song. Re-map any time for a fresh look.
Record 10s, 30s, 60s, or full song.
One click exports native H.264 + AAC MP4 at 1080p, 8 Mbps. Lands in your downloads folder. Plays in any video editor or straight to social.
Visual languages · 5 built-in
One engine. Five distinct aesthetics.
Each version is the same engine with a different blend / blur / grain / color treatment. Pick the one that fits your track. Switch any time — the audio reactivity stays.
Who it's for
If you have audio and need video, this is for you.
Independent musicians
You have the track. You need a YouTube visualizer, an IG Reel, a Bandcamp loop. Hiring an editor is €300+ and 1–3 weeks. This is €0 and one afternoon.
Producers & beatmakers
Sketch visual ideas for unreleased tracks without leaving the browser. The engine reads BPM and key, so the visual mood matches the track's actual emotion.
VJs & live performers
Use your own performance footage. The engine scores by motion, so a clip of a person dancing ranks higher than a still. Plug in a mic, layer live video over the song.
Designers prototyping motion
Need a 10-second mood piece for a brief? The engine is a fast way to test visual languages against an audio reference. Export, drop into a deck, iterate.

Don't want to drive it yourself?
The service tier is the rendered output.
The engine stays free and open. If you'd rather have someone render a 30-second MP4 from your finished track in 48 hours, that's a separate thing. From €25 per set, commercial rights included. See pricing & order →
