Convert MKV to WMV for Windows-specific environments that don't have MKV codec support installed.
MKV is a flexible, open-standard container format that can hold an unlimited number of video, audio, subtitle, and metadata tracks. It's the preferred format for high-quality video archival and media collections.
WMV is Microsoft's proprietary video format, commonly used in Windows environments. It offers reasonable compression but has limited support outside the Microsoft ecosystem.
MKV offers more features and codec support. WMV is limited to Microsoft codecs but plays natively on Windows.
