QuickTime Player comes natively installed on Mac, so you think that it’s the perfect solution to play MP4 files. However, you can only play files that have been encoded in a specific way using QuickTime Player, so you may need to look for some other app like Elmedia to play your MP4 files. 

If you don’t want to use a non-native video player, you could convert your MP4 files to a playable format that works with QuickTime. However, it’s easier to just use a third-party MP4 player.

Why can't QuickTime Player open MP4?

MP4 or MPEG-4 files are natively compatible with Apple’s QuickTime Player. However, QuickTime Player only works with files that have been encoded to meet Joint Video Team (JVT) standards. If the file you’re trying to play doesn’t meet these standards, QuickTime Player won’t play MP4 videos.

Another reason why the player won’t open your video could be because it’s either damaged or corrupted. In situations like these, you have two options: use a converter to change the video format or switch to a fully-featured video and audio player for Mac that will play any MP4 file you throw at it, regardless of how it’s been encoded.

Frequently Asked Questions

If you can’t open an MP4 file on Mac, it may be because your MP4 file has been encoded in a way that isn’t compatible with QuickTime, which means you’ll need to convert it to a compatible format or use a third-party player to play it. It could also mean that your file is damaged or corrupted.

QuickTime is the native player that comes pre-installed on Macs, and you can open most MP4 files on Mac using it, provided they have been encoded in the correct way. If QuickTime player can’t open MP4, you can use a third-party player.

MP4 files are natively compatible with QuickTime, but because these types of files can be encoded in different ways, you’ll need to ensure any file you want to play has been encoded with MPEG-4 or H.264 video code (and AAC audio codec). If your file uses different encoding, you won’t be able to play it with QuickTime.
