MPEG and AVI explained
MPEG-1 and MPEG-2 program streams are the formats behind Video CDs and DVDs. They are decades old and very inefficient by modern standards.
AVI is a Microsoft container from 1992. It predates modern video compression and lacks features taken for granted today, such as proper support for variable frame rates and modern codec metadata.
