What Is MKV? Complete Technical Guide to the Matroska Container
Understanding Matroska (.MKV)
The Matroska multimedia container is an open-standard, free container format based on Extensible Binary Meta Language (EBML). It can hold an unlimited number of video, audio, picture, or subtitle tracks in one file.
Unlike older AVI or MP4 formats, MKV natively supports advanced audio codecs (like Dolby TrueHD and FLAC), interactive menus, and styled soft-subtitles (ASS/SSA).
