Why TikTok Videos Experience Audio Desync After Uploading
If your video plays smoothly on your phone but audio slips out of sync on TikTok, the cause is almost always Variable Frame Rate (VFR). iPhones and OBS screen recordings adjust framerates dynamically (e.g. fluctuating between 54fps and 60fps). TikTok's server requires a strict Constant Frame Rate (CFR) of 30.00 or 60.00 FPS.
Frequently Asked Questions (FAQ)
Can I upload HEVC / H.265 videos to TikTok?
While modern iPhones record in HEVC, TikTok occasionally experiences longer processing delays and color shifts with H.265 files. Exporting in H.264 guarantees universal compatibility.
What causes a black screen on upload?
A black screen with audio playing usually occurs when uploading 10-bit HDR video without converting to standard 8-bit SDR Rec.709 color space.
