About AVI

Audio Video Interleave

Microsoft's RIFF-based video container from 1992. It is mostly found in older camera footage and DivX or Xvid files. Convert AVI to MP4 to play old clips on phones and current players, usually at a smaller size.

About FLV

Flash Video

Adobe's container for Flash Player, which carried most web video in the late 2000s, usually with Sorenson Spark, VP6 or H.264 video. Flash Player was discontinued at the end of 2020. Convert FLV to MP4 to play saved Flash-era video now that Flash is gone.
