Notes about the MKV file extension:



Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

The MKV file type is primarily associated with 'Matroska' by Matroska Association. The Matroska multimedia container formats were derived from a project called MCF, but differ from it significantly because it is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables future format extensibility, without breaking file support in old parsers. This is a container, not a CODEC. Get the parser from the Matroska site. MKV is the typical extension for a Matroska video file, it may contain several video tracks (in most cases only one), as well as several audio and subtitles tracks, in various formats. In addition to that the files can have attachements like JPEGs, song lyrics, decoder filters for DirectShow or other decoders, etc.

Other applications associated with file type MKV:

  • Matroska by Matroska Inc, Encryption in Matroska is designed in a very generic style that allows people to implement whatever form of encryption is best for them. It is easily possible to use the encryption framework in Matroska as a type of DRM. , , Because the encryption occurs within the Block, it is possible to manipulate encrypted streams without decrypting them. The streams could potentially be copied, deleted, cut, appended, or any number of other possible editing techniques without ever decrypting them. This means that the data is more useful, without having to expose it, or go through the intensive process of decrypting. , , Encryption can also be layered within Matroska. This means that two completely different types of encryption can be used, requiring two seperate keys to be able to decrypt a stream. , , Encryption information is stored in the ContentEncodings section under the ContentEncryption element. , The Mime types used with this association are: video/x-matroska.
