Can I Export iMovie to MP4 on Mac Directly
Can I export iMovie to MP4 on Mac? The answer is Yes! Yet one thing you need to figure out before exporting iMovie to MP4 is what file formats does iMovie export, since many users encounter the problem that iMovie always exports files into .mov format, which is incompatible with many media devices:

In case you want to know, as sharing iMovie through email or uploading to YouTube, Facebook, or Vimeo, the iMovie file will be saved as MOV format, which maintains the original video quality yet spontaneously brings up the file size. Thus if finding it inconvenient in this scenario, you can check some of the best video converters for help to convert iMovie to MP4.

2. How to Export iMovie to MP4 via QuickTime
QuickTime, developed by Apple Inc., wins a great number of users with its capabilities to handle myriads of formats of digital video, picture, sound, panoramic images, and interactivity.
Unfortunately, you can't export iMovie to MP4 using the latest version of QuickTime (QuickTime Player. Version 10.5). In the software, all videos will be exported as either .mov or .m4v, the latter being for iOS devices and Apple TV and the former for everything else.
However, you can try resort to manually change the extension to MP4, which will swap its container, but won't present real effect on the quality of the original file. But such method works under certain circumstances, and if the codec of the original video stream is not supported in the target container, file damaging or playback errors will crop up.

Note:
Previously, you can directly export iMovie to MP4 via QuickTime (Pro Version only). But since Apple ended support for QuickTime Pro in 2018, this method is no longer workable based on our test.
