What is AVI?

AVI (Audio Video Interleave) is a multimedia container developed by Microsoft in 1992 to work with its Video for Windows software. An AVI file can contain both audio and video tracks. AVI files also have higher quality than MP4 files, but they’re larger.

The AVI video file container isn’t used as often as it used to be because it’s not ideal for sharing or streaming video. AVI files also can’t support 4K or UHD resolution. You can play AVI videos with Windows Media Player, VLC, and several other AVI players like JetVideo and KM Player.

What is MP4?

MP4 is one of the most widely used video file formats. You can upload MP4 videos to popular social media sites like YouTube, Instagram, TikTok, Twitter and Facebook. Media players like Windows Media Player, VLC, QuickTime, iPhone, iPad and Android are also compatible with MP4 video files.

MP4s are popular not only for their compatibility with most devices but also for their ability to hold high-resolution videos without taking up much storage space. MP4 stands for MPEG4, and an MP4 file can contain video, audio, images and subtitles.
