First introduced in 1992 by Microsoft, AVI videos were the most popular type throughout the 90s and into the early 2000s.
It can only contain video and audio tracks, and it can actually hold multiple tracks of each but this feature is rarely used.
Readability of AVI is almost universal, but it has some compression limitations that result in larger-than-average files.
An AVI file uses less compression to store files and takes up more space than many other video formats-like
MPEG and MOV.
AVI files also can be created without the use of compression at all.
This makes the files lossless, which results in immensely larger file sizes-approximately 2-3 GB per minute of video.
A lossless file will not lose quality over time, regardless of how many times you open or save the file.
Other formats:-
MKV (Matroska Video Container): First introduced in 2002, the Matroska format is both free and open standard, which has helped it to stay relevant over the years.
MKVs can contain virtually all kinds of video and audio codecs, plus multiple subtitle tracks and DVD menus and chapters, making it the most flexible format currently available.
MP4 (MPEG-4 Version 2): First introduced in 2001 but later revised in 2003, the MP4 format took the then-popular QuickTime File Format and improved on it in several ways. It supports a wide variety of video and audio codecs but is most often used with H.263/H.264 for video and AAC for audio.
