Private ffmpeg conversion

Convert MOV to MP4

Make MP4 copies from iPhone and camera .mov footage. Many H.264 or HEVC MOV files with AAC audio convert near-instantly as a container change; other files need a full re-encode, so short clips are the realistic target.

About MOV and MP4 conversion

MOV is a familiar camera container, especially around Apple devices, but MP4 is easier to share with web apps, editors, and players that reject .mov uploads. This converter first tries to copy compatible streams into an MP4 container without changing the video or audio data.

If the copy remux fails, the page falls back to H.264 video plus AAC audio. That fallback is much slower: on HD clips, conversion speed depends on the device and can be roughly real time or below it. For big camera files, a desktop converter is still the better tool.

Browser ffmpeg loads once from this site at about 31 MB, the same engine used by audio conversion. After that, the queue reuses it and the selected MOV remains local to your browser session.

FAQ

Why are some MOV files converted so quickly?

When the MOV already contains MP4-friendly streams, ffmpeg can copy them into a new container instead of re-encoding.

What happens if remuxing does not work?

The converter makes one fallback attempt that re-encodes video to H.264 and audio to AAC for a standard MP4.

Should I use this for long phone videos?

Only if the fast container copy applies. Full HD re-encoding in the browser is best kept to short footage.
