A music visualizer for the whole song, made for YouTube.

Made for a long video

• 16:9, start to finish. The YouTube setting renders the entire song with its audio.
• Up to 4K. 480p is free; 1080p and 4K come with Single Video or Pro. The bitrate follows YouTube’s recommended upload rates.
• Visuals that keep moving. Switch every few beats or seconds, at each new track, or at moments you mark. Fill the song picks the visuals for you.
• Chapters for a mix. Open several tracks as one mix and the finished render gives you YouTube chapters to copy, and a schedule with every scene, its preset and its author.
• No dead air. Check scenes for blank spots plays the video quickly at a tiny size and replaces scenes that sit black with your song.
• Long renders, in parts. In Chrome and Edge, Render in parts saves the video piece by piece: a crash costs one part, and the render carries on from there.

From song to upload

   Pick visuals by mood or press Fill the song, then choose when they switch.

3. Render in 16:9

   Choose YouTube under Made for, pick a size and save the MP4, ready to upload.

Questions

How long can the video be?

As long as your song or mix. Long 4K renders take a while and need a desktop with a decent graphics chip; the studio tells you what your browser can do.

Which file does it save?

An MP4, using the best codec your browser can encode, H.264 first.

Can I use any song?

Use music you own or are allowed to use. BeatFractal never receives your song, and YouTube checks what you upload.

Can I credit the visuals I used?

Yes. After each render, BeatFractal lists the presets the video showed, with their authors, ready to copy into the description. The schedule file adds the time of every scene.
