Upload your MP3, pick a visual and watch it react to every kick, bass line and vocal. KOSMOVIZ renders on your own graphics card in the browser and exports a 16:9 MP4 that is ready for YouTube. The free export has no watermark.
How it works
- Upload your track as MP3.
- Choose a visual from the library and adjust colours, text and effects.
- Export as MP4 in 16:9 and upload it to YouTube.
Why KOSMOVIZ
- No watermark on the free export. Your channel, your branding.
- Real GPU rendering. Visuals are rendered on your graphics card in the browser, so the preview is the final video.
- Built for music. Every visual reacts to the analysed audio, not to a generic volume meter.
- Higher quality when you need it. 720p, 1080p and 60 fps are paid exports.
FAQ
Is it really free?
Yes. The free export is 480p at 30 fps without a watermark. Higher resolutions are paid exports.
Do I need to install anything?
No. KOSMOVIZ runs in a current browser with WebGPU; older browsers fall back to WebGL2.
Which format does YouTube need?
16:9. KOSMOVIZ also exports 9:16 for Shorts and 1:1.
Can I use AI-generated music?
Yes, for example Suno exports. You need the rights to the track you upload.
