About the formats

Extension wmv
Category Video file formats
Developed by Microsoft
Mime type video/x-ms-wmv

Description

WMV stands for Windows Media Video. Based on the Microsoft Advanced Systems Container Format (ASF), WMV files are meant for streaming and playing with Windows Media Player and the newer Movies & TV app on Windows 10 and 11. Note that WMVs can be encrypted with DRM protection.

To achieve greater compatibility, you can convert WMV to MP4 or another video format.
Extension mkv
Category Video file formats
Developed by Matroska
Mime type video/x-matroska

Description

MKV files are MatrosKa Video files. Like the Russian Matryoshka doll, which contains multiple smaller dolls nested inside each other, the MKV format can contain multiple video, audio, and subtitle tracks inside a single file. This makes it convenient to have one video with a number of audio and subtitle tracks in different languages, all inside a single playable file.
