WMV is Microsoft's proprietary video format, commonly used in Windows environments. It offers reasonable compression but has limited support outside the Microsoft ecosystem.
WebM
WebM is an open, royalty-free video format developed by Google, optimized for web use. It uses VP9 or AV1 for video and Opus for audio, offering efficient compression ideal for HTML5 video and web applications.
WMV is Windows-specific. WebM is web-optimized and open source. WebM delivers smaller files for web use.
