MKV and WebM descriptions

What are MKV and WebM?

MKV is an open format designed to hold an unlimited number of video, audio, picture, and subtitle tracks inside a single file. MKV is intended to serve as a universal format to store common multimedia content such as movies and TV shows.

WebM is a multimedia format sponsored by Google, among other companies, for use with HTML5 video. The WebM format was developed with the goal to create a completely open and free multimedia streaming format for use on the Internet. WebM is encapsulated as a Matroska file using VP8 to encode video and Vorbis to encode audio. Both VP8 and Vorbis are based on free and open standards. By using the WebM format, developers eliminate potential third-party patent issues related to some of the other encoding technologies such as H.265, H.264, and MPEG-4.
