Comparison Between AVI & MP4 Format

AVI, or Audio Video Interleave, is a multimedia container format introduced by Microsoft. This file format contains both audio and video data in a file container that allows synchronous audio-with-video playback. AVI files use less compression to store files and take up more space than many other video formats—like MPEG and MOV. How to play an AVI file? 

  • Windows users: use Windows Media Player or other supported applications.
  • Mac/Linux/Android/iPhone users: use VLC player.

MP4, or MPEG-4 Part 14, is also a multimedia container format used to store video, audio, subtitles, and images into one single file. MP4 is an embodiment of the QuickTime format of 2001 and has a standard .mp4 extension. So if you're looking for a standard video format that's acceptable on all devices and websites, MP4 is your go-to option.
