We use the MP4 file format for our video downloads.
MP4 files were created under the ISO/IEC 14496-12:2001 standard by the ISO/IEC and Motion Picture Experts Group (MPEG). Because of this, MP4 is an international standard for audio-visual coding.
While MP4 files can play audio, they shouldn’t be confused with M4A and MP3, as these are file formats that only contain audio (with the exception of M4A which can contain slides using supported players).
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 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. If you are not able to play MP4s, 3rd party apps and players, like VLC, may be needed.
