Google is serious about WebM: the video collection Youtubes is a message in the official YouTube blog after already to 30% in the open-source and royalty-free WebM coded - new videos anyway parallel to H.264 to WebM encoded (videos are uploaded every day with the total duration of 6 years!). So soon the whole video is in YouTube&s inventory and therefore available via WebM HTML5 be. An interesting information: the 30% of the videos account for 99% of the views - that is the Long Tail of the once and never again be watching videos probably pretty thin. In order to protect themselves against claims of the MPEG LA Google has WebM Community Cross-License started, which consists of several companies that license their codec technology WebM question each other for free to establish themselves as WebM open codec in the network and to support a patent. More on YouTube&s technical infrastructure, the encoding of the videos by Cloud worried here. The secret of the almost immediate availability of the videos after the upload is in the immediate creation of a base version during the upload and the parallel computing of individual parts of the video by Cloud. And YouTube is getting faster with the encoding of the videos: compared with 2008 is compressing now 7 times as fast.
