Common File Extension Variations: MKV, mkv

Author: Matroska Association

The MKV file extension is used to refer to Matroska video stream container files that can contain multiple video tracks. Matroska MKV files were developed based on Extensible Binary Meta Language - EBML - an XML derivative that uses binary code - but the MKV file itself is not a binary file. MKV files are not codecs and require the Matroska parser to access. MKV and other Matroska file formats are originally written in C++ programming code, but more recent versions have included C and Java. MKV files can be edited with the appropriate software.
