What AVI and MP4 files are
AVI
AVI (Audio Video Interleave) is a video container Microsoft introduced in 1992 with Video for Windows. It still opens in most desktop players and editors, but it has no standard field for aspect ratio and was not designed for how modern codecs compress video, so MP4 is the safer choice for phones and the web.
MP4
MP4 is the most common video container, holding video, audio and subtitles in one file. It balances quality and file size well and plays on phones, browsers, TVs and editing software alike.
