Frequently asked questions
What plays MP4 files on Windows?
Learning how to play MP4s on Windows 10 is largely a question of using the right software for the job. MP4s are widely supported by all sorts of media players. Windows Media Player is a great MP4 player on Windows, and is part of the main Windows install. VLC is a popular third-party media player which is also good for playing MP4s.
Does Windows Media Player play MP4?
For Windows 10, MP4s are most easily played on Windows Media Player simply because it doesn't require any additional software installs. If that doesn't work for some reason, VLC is a great alternative. There are also a number of fixes that can be applied if you particularly want to play an MP4 in Windows Media player or you are having trouble playing MP4 files in some other software.
Which MP4 codecs are supported on Windows 10?
Windows 10 includes a wide range of codecs that make it possible to play all sorts of file formats, from AVIs, to MP3s. It also fully supports both MPEG-4 and H.264 for playing MP4 files in Windows Media Player.
MP4 files are so widely supported that most media players, including Windows' own, can play them without the need to download additional codecs. However, if you run into problems playing MP4s on Windows, then updating your codecs with a robust codec pack can sometimes fix the issue.
Why VLC won't play MP4
The VLC media player MP4 playing experience is typically solid. VLC should be able to play MP4 files without the need for tweaking or adjustments of any kind. It's a media player with extremely broad support for almost all video and audio files and is a great option if you find that Windows Media Player or your other preferred player can't play a video file properly.
If you run into an issue where VLC won't play an MP4 file, it could be that the file you're trying to play isn't an MP4 at all. It's worth running a virus scan on it to make sure that it isn't malware. Alternatively, download the file again to see if that fixes the problem – it might have been corrupted when it was downloaded.
If you're certain that you are trying to play an MP4 file but it still doesn't work, try downloading a codec pack before attempting to play it again. It might be that your PC just needed the right codec for the job.
If that doesn't work, try converting the file from MP4 to something else, like an AVI. That's also a robust and well supported file format that most media players, including VLC, should have no trouble playing.
