Why Is Frigate Recording Audio Out of Sync with Video?
- Input stream timestamp irregularity
- ffmpeg transcode buffer behavior
- camera stream profile mismatch
Problem Description
Frigate Frigate Audio Sync Drift pairing failures follow a short list of causes — this guide works through them from most to least common.
Why This Happens in Real Homes
Why this happens in real homes usually comes down to environment and timing, not instant hardware failure. Recorded clips play with noticeable audio-video timing mismatch. The pattern people actually report is Audio lags video, sync drift increases, and live view may look normal
The most common real-world triggers are Input stream timestamp irregularity, ffmpeg transcode buffer behavior, and camera stream profile mismatch. The fix is most reliable when the sequence is followed exactly: Check source stream timestamps, then Tune transcode settings, then Verify long-clip sync. After the repair, run multiple command and automation checks so the issue does not reappear later in the day.
Symptoms
- Audio lags video
- sync drift increases
- live view may look normal
Recognize these? Here's what usually causes it.
Common Causes
- Input stream timestamp irregularity
- ffmpeg transcode buffer behavior
- camera stream profile mismatch
Most fixes happen in the first 3 steps.
Do not tune only short clips when drift appears over time.
Tools & Requirements
Step-by-Step Solution
Check source stream timestamps
Validate camera feed has consistent PTS behavior.
Tune transcode settings
Adjust ffmpeg flags to reduce drift accumulation.
Verify long-clip sync
Test short and long recordings after changes.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If pairing fails after multiple attempts, the device may still be registered to a previous account — factory-reset it before trying to add it to a new one.
A/V sync should be validated under sustained recording conditions.
Pairing failures almost always come down to distance during the initial handshake — manufacturers seriously understate how close you actually need to be.
