I don't see much benefit to support HTML5 in webm or theora. One of the benefits of html5 over flash was the prospect of better resource handling and smooth play, but now as systems get faster, and flash better, there is less and less reason to go down this path. h264 is smooth enough in flash now, and it's about to get even better in the new flash release. There are no real hardware/product reasons for websites to support webm right now. h264 on the other hand gets the benefit of working with all the iphone and more recently apple tv. Promised new update this year will even allow HTML5 video to be streamed to apple TV directly from the browser of iphones, ipads, and i imagine safari. This is one of these technologies that will really increase the use of h264. I run the larges cycling site and we handle 100s of niche video uploads per day so I follow this closely, and as much as I'd like to jump on webm, I'm going to definitely hold of. Currently we convert videos to 3 formats to try handle all cases, and having to now multiply that by 2 with another codec is a lot of extra resources. 2.5 mbit h264 web HD/appletv h264 1 mbit h264 for web SD/iphone 300 kbit mobile - webm makes no sense in the short term. - you need apple support to make webm happen faster Think about all the extra resources, time, effort that you are asking from companies in the world to support the 2 formats. If you want to be efficient with society, keep the support of h264 while webm development happens, transition once all the big players support the new format. Alternatively take all the money/time/efforts and get apple to transition. If apple does not jump on the wagon, it's going to be years and years of wasted resources in society.
