Both MOV and MP4 are container formats for audio, video, and text. MOV format was initially developed by Apple for QuickTime player and gradually accepted widely. MP4 format supports more video/audio coding format and subtitle/caption formats than MOV does, such as VP8, VP9, AV1, FLAC, DTS, along with others. They can all store commonly used video and audio codecs, including H.264, H.265, MPEG-4.

MP4 and MOV Compatibility

When it comes to compatibility, MP4 wins. MOV designed by Apple is compatible with the Apple ecosystem, for example, Mac computers, iPhone, iPad, QuickTime Player, Final Cut Pro, and so on. Now, many media players, video editors, and video sharing sites accept MOV file type. MOV videos may run into trouble when processing on Windows though MOV is claimed to be suitable for Windows Media Player 12, and Windows operating system. MP4 is universally accepted. MOV and MP4 are friendly with the following mainstream players, editors, and video sharing sites.

Media players: VLC, Windows Media Player, QuickTime Player, 5KPlayer, Potplayer, KMPlayer.
Video editors: Adobe Premiere Pro/Rush/Elements, Lightworks, DaVinci Resolve, Sony Vegas Pro, Final Cut Pro X, Hitfilm Express, Shotcut.
Video sharing sites: YouTube, Instagram, Facebook, Dailymotion, Twitter.

However, you need to know that MOV and MP4 are just container formats, whether they are supported also depend on the video and audio codec formats they hold. Speaking of codec format, things become more complicated. Normally, you won't go wrong with MP4 with H.264 format and AAC audio. That's why many users choose to convert MOV to MP4 format. Twitter mobile app prefers MP4 and MOV formats, on the web, only MP4 video with H.264 and AAC codec formats are accepted. So, MP4 with H.264 video codec format has widespread support.

MP4 vs MOV, Quality

There's no difference between MP4 and MOV format in terms of quality. Many users on the DJI forum ask which format delivers better quality for shooting on the Mavic/Phantom drone series. In fact, quality is determined by resolution, bit rate, and compression algorithm (codec). As we mentioned above, MP4 and MOV are just containers that don't affect the quality of the encoded videos. MOV and MP4 video playback quality is the same if they use the same compression standard and recording settings. MP4 or MOV, it depends on what platform you are processing your content. That is to say, when choosing MP4 or MOV, compatibility is the factor you have to consider.

MP4 vs MOV, File Size

MOV and MP4 are just containers that have nothing to do with file size. The only factors affecting video size are video length and bitrate. The size is the duration times the bitrate. MOV and MP4 are just wrappers where the data is stored. Different wrappers support different codecs, but they don't affect the overall file size. It's wrong to say MOV files are bigger than MP4 and change MOV to MP4 for smaller file size. Learn the right way to compress large MOV files. The settings you use when encoding video have a great influence on file size.

MOV vs MP4, What Is the Best Video Format to Use?

To sum it up, both MOV and MP4 containers don't have an effect on the quality and file size of the final encoded videos. Choosing MOV or MP4 format depends on what you want to do with your videos. If you play or edit the video on the Mac community, the MOV format is suitable. If you are going to put the resulting video on Windows computer, Android mobile devices, or share with other people, you are safe with MP4 H.264 format that has universal playback support.
