AVI vs MP4

AVI, standing for Audio Video Interleave, is a multimedia container format developed by Microsoft. An AVI file uses less compression to store files and takes up more space than many other video formats.

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. It is a standard video format that’s acceptable on all devices and websites.

AVI videos or movies generally have a large capacity and great picture quality, which is more suitable for watching on a computer. However, if you want to watch on a mobile device, it is recommended to convert AVI to MP4 format. The picture quality is not bad, while the file takes up less memory.
