About these formats
FLV is the old Adobe Flash video format. Since Flash was discontinued, FLV files won't play in modern browsers, so converting them is usually the only way to watch them.
MKV (Matroska) is a flexible open-source video container that can hold multiple audio tracks and subtitles in one file, popular for high-quality rips and archives.
