What's MKV?
The MKV format (Matroska Video) is an entirely free video format. More precisely, it is a container making it possible to contain video (DivX, Xvid, RV9, etc), sound (MP3, MP2, AC3, Ogg, AAC, DTS, PCM), as well as subtitles (SRT, ASS, SSA, USF, etc) in the same file, other MKA for audio-only files and MKS for subtitles only. High Definition movies in 720 or 1080 pixel width format are often encoded and packaged as a Matroska format video with a MKV file extension. MKV files usually have a menu system slightly similar to a DVD menu, tools and libraries that allow developers to add MKV support to their applications, an audio/video cross-platform in a multimedia container format and streaming facilities over the internet. MKV has been licensed as an open source container format and is hence free for public distribution.
