MKV stands for Matroska Multimedia Container. It is a video container similar to MOVs and AVIs. The main difference is that an MKV format can hold unlimited amounts of audio, picture, and subtitle tracks (srt as an example). The MKV video format has the ability to store lots of useful information inside the container, like descriptions, ratings, cover art, and chapters. This is why MKV is the chosen format for DivX Plus software and DVDs since it was easy to display cover art and chapter information. MKV was initially released December 6 2002.
WebM is an audiovisual media file format. WebM is perfect for HTML5 video and the HTML5 audio elements. The video container was Initially developed by On2, Xiph, and Matroska. Later on Google picked up the project and actively maintains the WebM container format. The inital release for this container was May 18, 2010. From the webmproject.com site, this is how webm is described (WebM is an open, royalty-free, media file format designed for the web.). The WebM file structure is based on the Matroska container.
