"Chris Montgomery, otherwise known as Monty, is the founder of Xiph.org
foundation and creator of the Ogg container format. He has been
sponsored by Red Hat for several years to improve the codec quality of
Theora and the next generation version, called Thusnelda, is already
proving to be better than H264 as bitrate increases. Monty has posted
some test results demonstrating the improvements. Chris Blizzard from
Mozilla Foundation has some updates as well."
