What is an MP4 file?
MP4 files were created under the ISO standard / IEC 14496-12: 2001 by ISO / IEC y Motion Picture Experts Group (MPEG). Because of this, MP4 is an international standard for audiovisual encoding.
Initially created in 2001, MPEG-4 Part 12 relied on the QuickTime file format (.MOV). Current version, MPEG-4 Part 14, was launched in 2003. MP4 is considered a digital multimedia container format, essentially a file containing a large amount of data that has been compressed. The standard specifies how the data is stored within the container, but not how that data is encoded.
With the high degree of compression used in MP4 videos, this allows files to be much smaller than other video formats. Reducing the file size also does not immediately affect the quality of the file. Almost all original quality is preserved. This makes MP4 a portable and web-compatible video format..
While MP4 files can play audio, not to be confused with M4A and MP3, since these are file formats that only contains audio.

How do I 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 on your video and it will open with the default video viewer of your operating system. Android and iPhone also natively support MP4 playback; just tap on 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; on macOS, are played with QuickTime.
Nevertheless, if you prefer a different video player than any of those, changing a file's association is a simple process on Windows or macOS. And you most likely don't even have to do that. When you install a new video player application, the new application is very likely to claim the association with the MP4 files during installation, unless otherwise specified.
