WebM: Developed by Google, WebM is a container format that is based on Matroska and capable of holding videos in high quality. The format is supported in HTML 5 and was thus originally designed for the Web. To compress the videos in WebM format, VP8 or VP9 video codecs are used.

The format is widely used as it is compatible with almost all types of digital media devices and players. MP4 videos can also be streamed over the net. Advanced content like menus, user interactivity, and 3D graphics are also supported by MP4.
