Part 6. Comparison Between AVI and MP4 Format

AVI, also known as Audio Video Interleave, is a multimedia container format introduced by Microsoft. This file format can contain both audio and video data in a file container that allows synchronous audio-with-video playback. An AVI file uses less compression to store files and takes up more space than many other video formats—like MPEG and MOV. How to open an AVI file? Here are the answers:

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

MP4, specified as 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. You can also know more differences between AVI and MP4 in the table below:
