Standing for Windows Media Video, a WMV is a video format that is developed by Microsoft. This video compression format uses the Advanced System Format (ASF) by Microsoft as the container and it is most packed in Matroska or AVI containers. The format is designed for playing on Windows OS and is compatible with Windows Media Player and other windows-based players. A WMV file may store video clips, movies, animations, and also HD video content. These files are also capable of supporting the encryption to be used with DRM systems.
