What is MKV file and the method to convert mkv to wmv for importing to WMM

Do you know what is MKV file? Have you met some MKV file?

MKV stands for "Matroska Video". Matroska is a container file format, capable of holding unlimited number of video, audio and subtitle tracks, along with any metadata. Practically this means that it is possible to put entire movie with multiple sound and subtitle tracks, chapters information and movie thumbnail into single file.

There are many players and codec packs that enable MKV playback on any platform, be it Windows, Mac or Linux. However many hardware players do not play MKV directly - for that MKV files need to be transcoded into format that particular hardware player understands. It was derived from a project called MCF, but differentiates from it significantly because it is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables the Matroska Development Team to gain significant advantages in terms of future format extensibility, without breaking file support in old parsers. Matroska (MKV) is an open standards project.
