FLV conversion from WMV is only needed for legacy Flash-based systems.
WMV is Microsoft's proprietary video format, commonly used in Windows environments. It offers reasonable compression but has limited support outside the Microsoft ecosystem.
FLV was the dominant web video format during the Flash era. While Flash is now deprecated, FLV files still exist in many archives and legacy systems.
Both are legacy formats. Consider converting to MP4 or WebM for modern use.
