The most common iPhone problem: a video that will not upload or will not play on Windows.
MOV is the QuickTime container, and MP4 was built directly on top of it, which is why the two are so alike. It is the native output of iPhones and Final Cut, and it can carry professional codecs such as ProRes that MP4 files rarely hold.
MP4 is the format the world settled on. It is a container rather than a codec, almost always holding H.264 video and AAC audio, and there is no device, browser, editor or social platform that refuses it. If you are not sure what to convert something to, the answer is MP4.
| MOV | MP4 | |
|---|---|---|
| Released | 1991 | 2003 |
| Developed by | Apple | MPEG |
| Type | Container | Container |
| Usual codecs | H.264, ProRes, HEVC | H.264 or H.265 with AAC |
| File size | Large with professional codecs | Small for the quality |
| Best suited to | Editing on a Mac | Everything, honestly |
| Support | Good, best on Apple | Universal |
The video is decoded and re-encoded, which costs a small amount of quality - invisible once, noticeable if you convert the same clip back and forth repeatedly. Resolution, frame rate and aspect ratio are preserved. Going from MOV to MP4 changes the wrapper and the codec, not the footage itself.
Video takes real time. A short clip finishes in under a minute, while a full-length film can take considerably longer, because every frame has to be decoded and encoded again. Uploading a large file is usually the slowest part of all.
Your file is uploaded to our server because the conversion runs there. A cleanup task runs every hour and deletes anything older than an hour, so nothing you upload survives more than about two hours. We do not open your files, we do not keep copies, and no account is needed to use the converter.
