MKV preserves WMV content while adding modern container features like multiple tracks and better metadata.
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 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 limited container. MKV is an open, flexible container supporting virtually any codec.
