In a recent interview, Wikimedia deputy director Erik Moller talks about the site's upcoming suite of editing tools and sharing options. "Although videos have been part of the Wikimedia stable for a couple years through the open-source Ogg Theora format, the offering has been limited. Now, however, a Firefox 3.5 plugin called Firefogg will allow for server-side transcoding to the Ogg format. In addition to allowing for downloading and editing, the Ogg format also consumes significantly fewer resources during video playback. The linked article also indicates that there are other video sites (apart from Wikimedia and Dailymotion) that are moving to the open standards format for video, noting that "hundreds of thousands of public domain videos from sources such as the Internet Archive and Metavid will be available in the new format".

Why is this apparently so difficult for you to grasp?
Well, I make sure that my posts are well-written, but English isn't my primary language... So, in case my last post wasn't clear enough, let's try again:
H.264 implementations can improve, just like H.262/MPEG-2 implementations greatly improved in ten years and Theora is improving with Thusnelda. It's just wrong to compare a standard (H.264) with an implementation (Thusnelda), unless you believe that comparing apple with shuttles can make sense!
Never said that Theora implementations cannot get better than the best H.264 implementation, etc. Don't get too defensive!
By the way, there's no need to give me a lecture in video compression... I am familiar enough with the bases.

The only other point I would make in addition is that right now Theora is making startling progress, to the point where it appears to have caught up to h264. This is no doubt due to some financial help donated by Mozilla.

H264 appears to be asleep on the job, resting on its laurels, as it were.
If you are truly up with the news on the topic of video decompression, I would have thought you would have been aware of all this.

Exactly so.
The encoder is the function which determines the compression efficiency and therefore the required bitrate and filesize for a given video quality.
Up until recently, h264 encoders have been a lot better than Theora encoders.
Just recently, the Theora encoders under development had all but caught up.
I would speculate that by right now (ie today), the developmental Thusnelda encoder for Theora (which is at some point past alpha 2 stage) is just about on parity with any h264 encoder.
