<\/span>What is MKV File Format?<\/b><\/span><\/h2>\r\n\r\n

A MKV file format is a container of video, audio and subtitles. It is based on Matroska<\/a>, which is an extensible open source, open standard multimedia container developed by the Matroska Organization.<\/p>\r\n

<\/span>Characteristics and Uses<\/b><\/span><\/h3>\r\n\"MKV\r\n

Matroska uses Extensible Binary Meta Language (EBML) for development. EBML is a binary derivative of XML, which enables extensibility. In this manner, the Matroska container can include future file formats, without losing support for old ones.<\/p>\r\n\r\n

The Header provides the EBML version of the file. The Meta Seek section contains an index. The Segment section includes file identification information. The Track section has metadata about each of the tracks. The Chapters section lists all of the chapters. The Clusters section has all of the audio and video content. The Cueing section contains cues, which are indices for each of the tracks. The Attachment section has all file attachments, and the Tagging section has all the tags for the file and tracks.<\/p>\r\n\r\n

The MKV file format divides the data into blocks. Blocks in turn are grouped into block groups and clusters. Time code metadata is defined in the blocks, block-groups, and clusters headers.<\/p>\r\n\r\n

MKV files support a variety of codecs. The subtitle formats supported are SRT, SSA, and USF (Universal Subtitle Format). It also supports VobSub for DVDs. It can also contain 3D video. The file format also supports encryption, and according to Matroska it can be used as a type of DRM. Matroska has also created codec identifiers similar to the FOURCC, and it has added other more specific identifiers.<\/p>\r\n\r\n

This file format is very popular among the anime fan-subbing community, which translates foreign films and foreign television programs into other languages. This popularity is based on the MKV support for multiple audio and subtitle tracks in the same file.<\/p>\r\n

<\/span>Brief History<\/b><\/span><\/h3>\r\n

The Matroska project began in 2002 as a split from the Multimedia Container Format project. The name Matroska derives from the Russian word for Russian doll. Matroska is supported by a non-profit organization in France.<\/p>\r\n\r\n

The project support is increasing. Later in 2010, it was announced that the WebM file format would be based on the Matroska container. In 2014 Microsoft said that the company would support Matroska out of the Box.<\/p>\r\n
