It has been almost a year since Google announced its open-source WebM video format, and now the time is right for YouTube to begin transcoding videos into this new format.
Folks from YouTube are already working hard on converting of most popular videos on YouTube to WebM, and according to them, it seems that about 30 percent of all videos have been converted to this format. In addition, all new vides are now automatically converted into WebM, a video format that is based around VP8 codec that is intended for use with HTML5 video.
