YouTube says that most of the most popular video clips on its projects are already available in WebM. As per YouTube estimates, very soon about 30% of videos will be transferred to the new format.
At the moment the videos uploaded by users are by default converted to WebM faormat, based on VP8 codec, and designed for use in HTML5. This standard is now supported not only by Google, but Mozilla with Opera also. In terms of formats, the new codec will compete with commercial format H.264, which is supported by Apple, and the latter has positioned it as a replacement for Flash on iOS-devices.
James Zern, an engineer with YouTube, said that technical staff is preparing in the future to move the entire YouTube directory to WebM. According to him, many videos uploaded in other formats, currently at the times of low load on servers are transcoded to the open format. Zern said that the technical staff is developing solutions for manual and automatic transcoding of content.
It must be recalled that in January this year, Google announced the withdrawal of support for H.264 codec from standard Google Chrome browser, and released WebM-plug-in for Microsoft Internet Explorer 9.
