On2 VP8
Did anybody get to beta test it? I don't see a personal use version on their site. I hope they release one.

Looking at the sample clip, it's interesting how they got x264 output to look like MPEG-4 (A)SP with all that macroblocking and somewhat annoying keyframe pumping. Would be nice to see the settings used. VP8 output on the other hand looks pretty much like x264 a year or two ago (without AQ and Psy RDO).

"...VP8 50% better than h.264" Hahahaahahah Good joke. Besides PSyRDO shows that in fact PSNR value is USELESS!!!!

3 years ago On2's devs made everything possible for that VP7 could compete with x264 (revisions 2xx). They constantly were updating their codec from VP7.0.0 to VP7.0.9.
I hope On2's devs will try to do the same for vp8. Of course now VP7 has no chance to be comparable to x264. Since then there was only misc. update vp7.0.10. I think the most important problems that VPx codecs have unstable local quality while overall quality isn't bad. VP7 has a problem with scene change. Key frames are highly quantized and rest of sequences recover details in temporal sequence. As a results there is no constant quality. Another issue is too strong deblocking filter. It's good only for very low bitrate. To compete with x264 they must plan long time development to achieve solid and well tuned codec. Just my opinion. And good luck for a small company On2. They aren't MS to spread millions for VC-1 and they must face big standard. Last edited by IgorC; 14th September 2008 at 02:24. |

I would add that you routinely denigrates the work of others. It is a bad habit. VP8 is perhaps really better than H264. Who's know? Certainely not you at this time.

If I had a dollar for every company promoting their format as "far better than H.264" that then turns out to be a joke, I'd be rich. Extraordinary claims require extraordinary evidence, and On2 has provided neither. It doesn't help my expectations that, in their entire history as a company, On2 has never come out with a format significantly better than those existing on the market (at least as far as I know). Right now, they seem to be rather desperate given that their only popular product, VP6, has been rendered obsolete by Adobe. Also, I find it rather insulting that you imply I always denigrate the work of others. If you look at my responses to things like CoreAVC, the DivX encoder and decoder, and other such products, I am fully receptive to them. What I do not receive well are products that make wildly false claims in order to promote themselves. Say "this format will be good," not "this format will be 25% better than H.264." The former makes sense, the latter is complete marketing nonsense and I reserve every right to mock it ruthlessly until sufficient proof is given.

If I say "there is a giant 5 mile high monster in the Australian desert," you would tell me I'm nuts. Am I allowed to then say that you're trolling, since you don't know, and therefore shouldn't speak on the topic? Quote:

On2 has a particularly hard challenge because, as a promoter of purely proprietary formats, they have to both make a good format and make a good implementation--they are on their own. Even if they can overcome the odds and make a format that is significantly superior to H.264, if they are as obsessed with PSNR as they make themselves out to be, they surely have no chance of competing with x264. |
