'''Matroska''' (styled '''Matroška''') is a project to create a [[container format (digital)|container format]] that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file.<ref>[https://www.matroska.org/technical/elements.html Matroska v4 element specification] {{Webarchive|url=https://web.archive.org/web/20180204034747/https://www.matroska.org/technical/specs/index.html |date=2018-02-04 }}, Matroska.org. "TrackNumber: The track number as used in the Block Header (using more than 127 tracks is not encouraged, though the design allows an unlimited number)."</ref> The '''Matroska Multimedia Container''' is similar in concept to other containers like [[Audio Video Interleave|AVI]], [[MPEG-4 Part 14|MP4]], or [[Advanced Systems Format]] (ASF), but is an [[open standard]].

Matroska file extensions are ''.mkv'' for video (which may include [[subtitles]] or audio), ''.mk3d'' for [[stereoscopic]] video, ''.mka'' for audio-only files (which may include subtitles), and ''.mks'' for subtitles only.<ref name="mk3d">{{cite web |url=https://www.matroska.org/technical/guides/faq/index.html#q3 |title=Matroska FAQ - Q3: What file extensions does Matroska use? |website=www.matroska.org |language=en |access-date=2018-07-16 |url-status=dead |archive-date=2019-04-08 |archive-url=https://web.archive.org/web/20190408035211/https://matroska.org/technical/guides/faq/index.html#q3}}</ref>
