AVI vs MP4: What Is the Difference

by Kayla Morrison • 2020-05-22 14:34:32 • Proven solutions

So AVI vs MP4, which is the better format? Well, that’s what this guidepost will be answering. If you like watching movies, especially on your computer, you must be conversant with both AVI and MP4 file formats. Although these files have a lot in common, there are also some glaring differences in terms of audio/video quality, speed, and playback. So today, I’ll polish you with all some details about these two video formats and how to transcode them for free.

Part 1. Is AVI Better than MP4

AVI Definition

AVI (Audio Video Interleaved/Audio Video Interleave) is a container format that was founded by Microsoft in 1992 during its Video for Windows software project. AVI files have a .avi extension and contain both video and audio data. It also supports multiple streaming of audios and videos, just like the DVD format. However, AVI doesn’t have some features found in newer container formats like MP4 and MPEG because it’s an older format. But whatever the case, AVI is undoubtedly an accessible video format.

MP4 Definition

MP4 or MPEG-4 Part 14 is a digital container format that was founded by the International Organization for Standardization in 2004. Just like AVI, it contains both video and audio data. On top of that, MP4 can also hold captions, subtitles, and still images. It also allows internet streaming. 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.
