About the product

What does sync.video do?

sync.video is a free set of browser tools for getting sound and picture back in step. Fix audio delay opens one video on a waveform timeline: Detect automatically matches claps and sharp sounds to changes in the picture, or you mark the clap frame, then nudge the sound in 1 ms steps and replay at half or quarter speed. Export copies the picture frame for frame, so nothing is lost. Sync separate recordings matches up to eight cameras and recorders by their sound and can hand over an FCPXML or Premiere XML timeline. Files stay on your device; no account, no watermark. Submitted by the sync.video team.
