Why Convert MKV to FLV?
FLV (Flash Video) is a legacy format — Adobe Flash was discontinued on December 31, 2020, and modern browsers can't play FLV files. Converting to FLV is only needed for compatibility with archived Flash-based systems, legacy content management platforms, or specific industrial applications that still use Flash video.
