Turn any track into a living video: visuals that hit with the kick, breathe with the bass and flare on the drop. Your photo or cover art in the scene, MP4 out in 9:16, 1:1 or 16:9 — and your track never leaves your browser.

This isn't a static waveform slapped on a background. Every scene listens to your track: smoke curls with the bass, rings punch on the kick, lasers cut through on the drop. Cinematic packs, neon packs, vinyl and cover-art scenes — each one tuned frame by frame.
Use your artwork, a photo or a short clip as the backdrop — visuals and lyrics render on top. The “living pixels” mode even warps your own footage in time with the sound.
Put your cover in the center like an official audio, add the artist name and track title, drop in your logo. Everything is drag-to-place on the canvas.
One project — three aspect ratios: 16:9 for YouTube, 9:16 for TikTok, Reels and Shorts, 1:1 for feed posts. Same scene, re-framed, exported as MP4.
Everything runs in your browser — analysis, rendering and MP4 encoding included. Your track is never uploaded to any server. That's also why it's free without a watermark: there are no server costs to recover.

On desktop Chrome or Edge the render runs faster than real time: a three-minute track finishes before it would have finished playing, and you can leave the tab in the background while it works. On a phone the same visuals appear and the same project opens, but the recording path is slower — roughly the length of the song — and the tab needs to stay in front. Nothing about the picture changes; only how the frames get written. If you have a computer to hand, build there and use the phone to watch and share.
Three things, and none of them is the number of templates. The first is whether the motion agrees with the music — a scene that pulses on a steady timer reads as decoration, while one that jolts on the kick reads as part of the track. The second is resolution and bitrate: heavy gradients and particles band badly at low bitrates, which is why a 360p free tier looks cheap no matter how good the template was. The third is your own material in the frame — cover art, a real photograph, a logo — because a stock scene with no trace of you in it looks like every other stock scene.
Artists shipping a release. The single drops Friday, there is no music video, and YouTube and Reels both want something to look at.
Beatmakers. A beat store where every clip looks consistent, built in minutes rather than an evening in After Effects.
Podcasters. An audio episode becomes a YouTube upload where the words are visible, not just audible.
Labels and managers. A whole back catalogue can be given the same visual treatment without a per-video invoice.
