What is an mp4 file? The mp4 file was created under the ISO/IEC 14496-12:2001 standard by the ISO/IEC and the motion picture expert group(MPEG). Because of this, mp4 is an international standard for audio-visual coding.

It was initially created in 2001, and MPEG-4 part 12 was based on the quick time file format. The current version MPEG -4 part 14 was released in 2003.

 How to Open an MP4 File?

Because MP4 is a standardized file format for video, almost all video players support MP4. To open a file, all you have to do is double-click your video, and it will open with your operating system’s default video viewer. Android and iPhone natively support playback of MP4 as well—just tap the file, and you’ll be watching your video in no time.

Windows and macOS users can play MP4 files without having to install any third-party software. Windows uses Windows Media Player by default; in macOS, they’re played using QuickTime.

however, if you prefer a different video player than either of those, changing the association of a file is a simple process on either Windows or macOS. And you most likely won’t even have to do that. When you install a new video playback app, the chances are high that the new app will claim the association with MP4 files during installation, unless specified otherwise.
