MKVToolNix is a set of tools to create, alter, split, join and inspect Matroska files (MKV). With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. Matroska is a new multimedia file format aiming to become **the** new container format for the future.
