Beatform

Beatform is a free, open-source music visualizer for Windows. Drop a track in, get a beat-locked video out — live preview and exported file are the same render, by construction.

Download the latest release (NSIS installer or MSI + SHA256 checksums). No account, no cloud, no telemetry; GitHub is the only channel and everything is free forever.

Fifteen minutes to a finished video

1. Install and open. Three synthesized demo tracks are built in — press play on one to see everything moving before you touch a file of your own.
2. Drop your track anywhere on the window (MP3/FLAC/WAV/OGG/M4A). The app reads its tags, detects BPM + key, and locks grid-synced visuals to the real beats.
3. Pick a look. Sixteen visual modes across the top; each ships 5–7 curated styles. Or open Settings → Templates and click a factory pack — Trap Nation Classic, Midnight Phonk, Lo-fi Haze, Outrun Nights, and more — for a complete tuned setup in one click.
4. Make it yours. Layers adds your title (auto-filled from tags), logo, or album art. Sync chooses what drives the motion (kicks, bass, melody, voice…). Post adds bloom, grain, vignette.
5. Export. One MP4 (H.264/HEVC/AV1), a transparent WebM (VP9 + alpha), a PNG sequence with alpha, or a ProRes 4444 .mov for your editor. What you previewed is what renders — sync is sample-exact.

Highlights

• Beat-grid sync: offline tempo tracking places beats on the audible transients (±6 ms, regression-tested); grid-locked visuals ride the real beats and fall back to onset pulses when a track has no grid.
• Batch render: drop 20 tracks in, get 20 titled videos out — titles come from each file’s own tags. Unattended, per-job isolation.
• Music library: point at your folder once, click tracks to play, near-gapless auto-advance.
• Listen to the system: visualize whatever the PC is playing (Spotify, a browser, a DAW) via native loopback — live, no setup.
• Deterministic renders: same input, byte-identical frames, every run.
