The amount of intellectual dishonesty here is staggering.<p><i>On the quality side what we’ve been able to do at Mozilla, with the help of the rest of the Xiph community, is to show that even though Theora is based on older, royalty-free technology, it does at least as well as H.264 in practice (although not always in theory.) If you don’t believe me check our Firefox 3.6 introduction video which is available in both Theora and MP4 formats. The MP4 version of the file is 13 and the Theora version is 8.2MB – about 40% smaller. (We actually think the Theora video looks better, too.)</i><p>Not only did he intentionally encode the MP4 really badly, which might be theoretically excusable--the MP4 file has two hint tracks as big as the entire video and audio stream, doubling the size of the file.  In short, he intentionally bloated the file with junk data to make it larger.<p>Lying apparently means nothing when you're trying to promote your pet file format.  Why are we letting these people be the voice of the free software community?
