Issue 1
Video glitches when watching on phone
Reset the TikTok app cache, then reopen the video. Cached playback can keep showing a broken version even after the upload is fine.
Issue guide
Fix Upload120 playback and loading issues.
Most problems come from TikTok cache or files that are heavier than TikTok Studio likes to handle.
Recommended export before upload
Resolution1080x1920 or lower
Bitrate20 Mbps or lower
Smooth playbackUnder 50 MB
These are warnings, not upload blocks. Smaller files usually load faster in TikTok Studio and play smoother on phones.
Issue 2
Video takes a long time to load
Export the video at 1080x1920 or lower, keep the bitrate around 20 Mbps or lower, keep the final file under 50 MB when you want smoother phone playback, and avoid Alpha + RGB exports for uploads meant to play on phones.
Issue 3
TikTok Studio upload gets stuck
If the upload is just moving slowly, that can be normal depending on your internet speed. If it fully freezes, refresh TikTok Studio, log back in if it asks, disable any other method extensions, and choose the patched file again.
Issue 4
File is rejected or does not show up
Use MP4, MOV, or M4V from a desktop browser. Avoid odd export containers, renamed project files, or files that are still being written by your editor.
