Troubleshooting Audio and Video Desync in Threads Videos
Problem Summary
The video and soundtrack start in sync but drift apart as the clip continues playing.
Why This Happens
Some social video streams use Variable Frame Rate (VFR) encoding to reduce mobile data usage. Certain media players assume Constant Frame Rate (CFR), resulting in timing drift.
How to Resolve It
- Open the video file in VLC Media Player, which natively compensates for Variable Frame Rate timestamps.
- If playing on mobile, use the official Photos or Google Photos app rather than third-party editing tools.
- Clear your browser cache and download the file again to ensure no audio packets were dropped during download.
