Sync two dance videos in perfect time
Trying to play two clips at once and they keep drifting apart? Dance Analyser lines them up by the music so the same count hits at the same moment — then lets you nudge it frame-perfect.
Get two videos playing as one
No more mashing play on two windows and hoping they stay together.
Audio auto-sync
It matches the beat of both soundtracks and finds the exact offset — a late countdown or intro won't throw it off.
Manual nudge
Shift one clip earlier or later in small steps until it's frame-perfect, even while paused.
Locked playback
Both videos free-run together and stay glued — pause, scrub or loop and they move as one.
Movement fallback
No usable audio? It can line the clips up by the motion itself, so silent videos still sync.

Frequently asked questions
How do I play two videos at the same time in sync?
Load both into Dance Analyser. It aligns them by the audio so the same beat plays at the same instant, then plays them together — and you can nudge the alignment by hand.
How accurate is the auto-sync?
It cross-correlates the beat energy of both soundtracks to find the offset, then you can refine it in small steps for a frame-perfect match.
Can I sync videos with different music or speeds?
A single offset handles most cases; for performances at slightly different tempos, the comparison view aligns moment-to-moment so timing differences stay visible instead of being hidden.
Is anything uploaded?
No — all of it runs on your own device.
