OGV and AVI explained
OGV is the Ogg container carrying Theora video, an early royalty-free codec that has been comprehensively superseded by VP9 and AV1.
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.
