[Mp4-tech] a proprietary codec: VP6.2

[Boris Felts]

I don't think this means really anything...
1- we had taken the exact same input file from their previous
announcements, calculated the PSNR with H264 and obtained better
results, contrarily to what was published.
2- there is no indication of H264 profile used
3- it is only addressing progressive content (for which optimizations
are much easier)
4- VP6.2 has probably a lot of pre and post-processing. None is used
with the reference H264 implementation. 
5- the H264 reference codec is probably not as optimized as VP6.
Basically, they are comparing the results of (prefilter+ optimized
codec+postfilter) to (non-optimized codec) I don't think we can draw any
conclusion from that.
As an example, MPEG-2 started with bit rate around 5 to 6Mbps. We are
now down to 2 Mbps in some cases. The syntax and the technology has not
changed, but a lot of refinements (bit alllocation, pre and post
processing) has been introduced since the first codec release which
explains this overall reduction. You will also find a significant
difference between highly optimized MPEG-2 encoders and the MPEG-2
reference model.
I am not denying the visual quality of their implementation, but
comparing to H264 in these conditions to VP6.2 is not relevant.

As far as I follow the list, there was no discussion on the proprietary
codec of On2, VP6.2. They claim to have better performance with respect
to even H.264. The results they have posted on their webpages,
http://www.on2.com/vp6_psnr.php3?graph=Football_h264
http://www.on2.com/vp6_psnr.php3?graph=Salmon
indicate quite significant improvements. I wonder the core technology
they are using. Is it wavelet-based or another technoloy is used? Does
anyone in this list have an idea on this issue?
Best regards.
