What FLV and MP4 files are
FLV
FLV (Flash Video) is the video format made for Adobe Flash Player, and it was widely used for online video in the 2000s, including by early YouTube. Adobe ended Flash Player support at the end of 2020, so browsers no longer play FLV and converting it to MP4 keeps old recordings watchable.
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.
