MKV (Matroska) is a flexible open container that holds high-definition video, multiple audio tracks and subtitles in one file. It is popular for movies and archiving, but is not natively supported by every device or browser.
MKV plays in VLC and most modern media players; some phones, browsers and TVs need it converted to MP4 first.
WMV (Windows Media Video) is Microsoft’s video format, once common for Windows clips and PowerPoint. It keeps files small but plays poorly outside Windows — Macs, phones and web browsers often can’t open it, so MP4 is the safer choice for sharing.
WMV plays in Windows Media Player and VLC; on Mac, phones or the web, convert it to MP4 first.
