What is MKV file format?

Known as MKV, the Matroska Multimedia Container is a free open video format that enables you to store a vast array of video, audio, image, or subtitle tracks within a single file.

Although MKV shares similarities with other containers such as AVI, MP4, and ASF, its fully transparent specifications & predominantly open-source software implementation sets MKV apart.  


When utilizing MKV, the file extensions vary depending on the content type. For video files that may include subtitles or audio, the extension is .mkv. Stereoscopic videos are denoted by .mk3d, while audio-only files adopt the extension .mka. Subtitles-only files carry the .mks extension.

Why is MKV good?

In the MKV file format, data is organized into distinct units called blocks.

These blocks are further grouped together into block groups and clusters. Within these structures, important time code metadata is specified, which includes headers for the blocks, block groups, and clusters.


Within MKV files, a wide range of codecs are supported, catering to diverse multimedia needs. Notably, it extends its support to subtitle formats such as SRT, SSA, and USF (Universal Subtitle Format).

For DVDs, MKV includes compatibility with VobSub. Additionally, the format is capable of accommodating 3D video content.

The MKV file format has gained significant popularity within the anime fan-subbing community, where enthusiasts translate foreign films and television programs into different languages. This widespread adoption can be attributed to MKV’s exceptional capability to house multiple audio and subtitle tracks within a single file.
