FAQ
What does it change?
Only the MP4 container: moov first, audio/video interleaving, extra sample-table entries, the bitrate box, timestamps and editor metadata.
Is my video re-encoded?
No. Every video frame and audio sample stays bit-identical.
Is my file uploaded anywhere?
No. It is processed in this tab.
Which files work?
MP4 or MOV up to 5 minutes and 4 GB, not fragmented.
Does it always work?
No guarantee: TikTok can change its pipeline any time. Upload on desktop web, not in the app.
