For editors matching a separate recorder track to camera footage, use your clap timecodes, frame rate, and timeline measurements to calculate an offset or spot drift that grows over a clip. Get suggested timeline adjustments, checks for sample-rate or frame-rate mismatches, and a step-by-step sync plan for your editing software. You leave with specific numbers and checks to try.

What it writes
- Audio offset in frames or milliseconds
- Sync troubleshooting checklist for your timeline
- Step-by-step drift correction plan
How to use it
Include your timeline frame rate, audio sample rate, clip duration, and two sync points—one near the start and one near the end. Those measurements distinguish a fixed offset from clock drift.
What you bring
- Project frame rate and editing software
- Audio sample rate and clip duration
- Clap times or sync offsets
- Know your project frame rate
A good fit for
- Matching a recorder track to camera footage after a shoot
- Fixing dialogue that drifts out of sync during a long interview
- Checking a frame-rate mismatch before syncing multicamera footage
Ways to start
A few requests this Agent can handle.
My camera clip is 23.976 fps and recorder WAV is 48 kHz. The clap is at 00:00:12:10 in camera footage and 00:00:11.84 in the WAV. What offset should I use?
Dialogue starts synced but is 18 frames late after 42 minutes. My timeline is 25 fps and the recorder file is 48 kHz. How do I diagnose the drift?
I have two camera angles at 29.97 fps and separate audio recorded at 44.1 kHz. What settings and sync checks should I use in Premiere Pro?
