Automatic beat detection

Cut your video to music — automatically

Syncing footage to a song by hand is the most tedious part of editing: scrubbing the waveform, dropping a marker on every beat, then nudging each clip until the cut feels on time. My Auto Edit does it for you. It listens to your track, finds the beat, and cuts your clips to the music automatically — so a montage that takes an evening by hand is ready in seconds.

Choose what the cuts follow

Different beats give a totally different feel. You pick; My Auto Edit syncs.

Kicks

Cut on the low-end thump for punchy, impactful transitions that match the groove.

Snares

Land cuts on the backbeat for a steady, musical rhythm to your montage.

Hi-hats

Fast, frequent cuts for energetic, hype edits that move with the track.

Energy peaks

Let the cuts follow the loudest, most dramatic moments in the song.

Why automatic syncing lands better

When you place cuts by ear, a few frames of drift creeps in and the edit feels slightly off even if you can’t say why. Because My Auto Edit cuts on the detected beat, every transition lands where the music actually hits. Prefer to compare approaches? Read auto vs. manual editing or the full step-by-step guide.

Cutting video to music — FAQ

How do I cut a video to music automatically?

Upload your clips, add a song, and My Auto Edit detects the beat and places the cuts for you. You choose which beats to cut on — every beat, kicks, snares or energy peaks — and it syncs the footage to the music automatically. Then you export.

Does it actually detect the beat, or just space cuts evenly?

It detects the real beat. The AI analyzes the audio to find the BPM and the individual kicks, snares and hi-hats, so the cuts land on the actual music — not on a fixed timer.

Can I sync video to any song?

Yes. Add the track you want and it analyzes that song’s tempo and beats. Songs with a clear, steady beat (most pop, hip-hop, EDM and dance music) sync best.

Can I adjust the cuts after it syncs them?

Yes. Switch which beat type you’re cutting on, or double-click the waveform to add or remove individual cuts before you export.

What can I make with it?

Beat-synced montages, Instagram Reels, TikToks, YouTube Shorts, travel recaps, gym and highlight edits — anything where the footage should move with the music.
