QuickTime Player is the default media player on Mac. Over the years, it has been updated with features that boost the user experience. But still, there is an ongoing issue in which QuickTime can’t play open MP4 files. Even though the format is the video standard and universally supported, it tends to not play on the media player. Fortunately, this is where you can find the solutions to fix the problem instantly.
You might have thought QuickTime can’t open MP4 files because it is not supported. But there can be other causes that won’t allow you to play a video on the media playback. To check what can be the cause, try these effective methods.
The first thing you must do when you can’t open MP4 with QuickTime is to give your device a simple reboot. Mostly, it might be experiencing overwhelming loads of information, causing an error on the playback.
Another method to do this is to update the media player. An outdated app is why QuickTime can’t open an MP4 file despite being supported. You can do it manually if the Auto-update option is not enabled to get the new software update.
Since the macOS 10.13 update, there are more codecs unsupported by Mac. MP4 is still a supported format for the media player, but it can only play files with H.264, MPEG-4, and H.265/HEVC codecs. Furthermore, the audio codecs are rarely supported within the platform. Instead, you can change the codecs of the MP4 file that the QuickTime player won’t open. Here, you can try an online converter.
