Try the live demo, no account neededA beat-synced video changes scenes exactly on the music's bar lines. MaestroCut does this by timing every scene in whole bars: at 120 BPM a bar of four beats lasts 2 seconds, so a 30-second promo is 15 bars. The score is composed for your video, or you pick a CC0 or CC BY track and the cuts follow its beat.

Frequently asked questions
How does MaestroCut sync cuts to the music?
+
Scene lengths are counted in bars of the music, so every cut lands on a bar line and accents land on beats. At 120 BPM a bar of four beats lasts 2 seconds.
Can I use a real track instead of the original score?
+
Yes. Pick a CC0 or CC BY track by an independent artist from the free library; its tempo and downbeat are measured in your browser and every cut is re-timed to it.
Can I use the music on Instagram and TikTok?
+
Yes. The default score is composed for each video, so there is nothing to license. Library tracks are CC0 or CC BY, which allow commercial use; for CC BY tracks the credit line is added to your caption.
What BPM should my promo video use?
+
It depends on the industry: the playbooks recommend 60–95 BPM for spas and 128–160 BPM for gaming; the average recommendation is 110.2 BPM.
How long should text stay on screen?
+
At least max(1.2 s, 0.35 s × words + 0.5 s). Because scene lengths are whole bars, the next cut still lands on the beat.
