Sync cameras by sound and cut between them
For interviews, podcasts, weddings and events: no clapperboard needed. CutLuma matches the recordings by their sound, then you cut between the angles like a live director.
Three steps, a couple of minutes
Add every recording
Put each camera, and your separate sound recorder if you used one, on the timeline and select them.
Sync by sound
Press Ctrl+K and choose “Sync clips by sound”. Each clip moves to the right moment, with a confidence so a bad match is never applied.
Cut between angles
Open the multicam viewer and press 1 to 9 while it plays, or let it follow whoever is speaking. Move or remove any cut later.
Why use CutLuma for this
Nothing is cut up
Angles stay whole and in sync; a cut list decides which one shows. Change your mind as often as you like.
Better sound
Replace the camera sound with the recorder’s in one click, or keep one camera’s microphone under every angle.
Finish your way
Flatten the cuts into ordinary clips to grade, trim and title them, or hand the edit to an AI agent.
Questions? Answers.
Is it free?
Yes, on every plan.
How many cameras?
Up to nine angles in one multicam.
Do the recordings need a clap?
No. Any shared sound works: speech, music, room noise. Recordings with no sound in common are refused instead of guessed.
My recorder drifts on long takes
The drift is measured and shown. On a long take the ends can be a frame or more out; splitting the take and syncing each part fixes it.
