What is a .MKV file?
MKV (Matroska) is a flexible open video container that can hold many video, audio and subtitle tracks.
- Did you know
- Matroska launched in 2002 as an open, do-everything alternative to AVI.
- The name Matroska is taken from the Russian matryoshka, the nesting doll, reflecting how it packs tracks inside one container.
- Matroska began in December 2002 as a fork of the Multimedia Container Format, after a dispute over using the EBML binary language.
- Matroska is built on EBML, the Extensible Binary Meta Language, so the format can be extended far into the future.
- On the web a .MKV file is served with the MIME type
video/x-matroska.
- What Analyser shows you
- Read the container, codec, resolution, and frame rate of MP4, MOV, MKV, AVI, and WebM video, step through frames, and extract the audio track. Raw H.264/H.265 elementary streams (.h264/.265) are remuxed to MP4 in-browser so they play too.
- Open a .MKV file
- Drag a .MKV file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
