For video editors matching separately recorded audio to camera footage, Sound Sync helps you pinpoint why dialogue or music drifts out of sync. Share timecodes, frame rate, and when the mismatch appears; get an offset calculation, a diagnosis of constant versus growing drift, and software-specific steps to line up the tracks. Leave with a sync plan you can apply in your editing timeline.

What it writes
- Audio offset in frames or milliseconds
- Constant-delay or clock-drift diagnosis
- Track-sync steps for your editing software
How to use it
Include the timeline frame rate, recording frame rates, and two matching event timecodes—one near the start and one near the end. That makes it possible to distinguish a fixed offset from clock drift.
What you bring
- Camera and recorder frame rates
- Matching clap or event timecodes
- Where sync begins and ends
- Know your editing software and timeline frame rate
A good fit for
- Dialogue starts in sync but drifts by the end of a take
- Matching a field recorder's audio to camera footage
- Fixing a constant audio delay in a finished timeline
Ways to start
A few requests this Agent can handle.
My 25 fps interview starts in sync, but audio is 12 frames late after 20 minutes. How do I tell if the recorder clock drifted?
I recorded a wedding on a 23.976 fps camera and a Zoom H5. The clap is at 00:03:14:08 in both files; what sync offset should I use?
In Premiere Pro, my external audio is consistently 8 frames ahead of camera sound. Give me steps to shift it and check sync across the clip.
