Multimedia, AV The debate about HTML5 video is for the most part pretty straightforward: we all want HTML5 video, and we all recognise it's a better approach than Flash for online video. However, there's one thing we just can't seem to agree on: the codec. A number of benchmarks have been conducted recently, and they highlight the complexity of video encoding: they go either way.

Agreed. Talking about Theora and H.264 would be fine except that many people believe VP8 will be the 800lb gorilla if Google make it available to use on favourable terms.

If we are talking about the future, the current development branch of Theora is called Ptalarbvorm (the previous development version which has now become Theora 1.1 the codename was Thusnelda). Weird names, I agree.

http://en.wikipedia.org/wiki/Theora

Like Thusnelda before it, Ptalarbvorm is optimisation of the Theora encoder only. Current Theora 1.1 players, such as the one embedded in Firefox 3.6, can play Ptalarbvorm-encoded Theora videos.

Anyway, the current experimental version of Ptalarbvorm is very promising, and initial results are finally getting better performance for Theora than h264 as currently used on the web. Theora Ptalarbvorm (experimental) at 376 kbit/s is approximately the same subjective quality as Youtube's current h264 implementation at 499 kbit/s.

If we are talking about the future, it may well not be either h264 or VP8 that yeilds the best performance for web video. It could well be the next version of the free and open Theora, already playable by current player software, that beats all comers.

Very possible. To quote a well-known little green alien: "Always in motion, the future is." Don't forget though that other codecs are also going to be concentrating on improvements. This is as it should be. Don't expect the rest to stand still as Theora improves.
