Newsmeldung von slashCAM:Hier geht es zur Newsmeldung: Comparison VP8 vs. H.264
Antwort von freezer:
The test is not very accurate, it is not even the exact codec settings mentioned. In the image comparison would be synonymous interesting to know whether it is an I, P or B frame.
The Sorenson Squeeze 6 MainConcept h.264 implementation is quite ok, but my experience is not enough s.die quality of x.264 up.
Much more interesting I find the analysis of the VP8 source code through one of the x.264 Developer:
http://x264dev.multimedia.cx/?p=377 Fits to synonymous frame comparisons of different codecs:
VP8 (On2 VP8 rc8)H.264 (x264 Recent) H.264 Baseline Profile (Recent x264)Theora (Recent ptalabvorm nightly) Dirac (Schroedinger 1.0.9)VC-1 (Microsoft VC-1 SDK) MPEG-4 ASP (Xvid 1.2.2)Hier sieht man deutlich,
far ahead of other codecs like x264 is over.

There is no longer the classic GOP structure in these codecs. An IDR, which is the I-frame still s.nähesten may appear ALLLE few frames dogs. That which is called B-frame in the codecs are in fact only slices, consisting of different (classes) and compositions of macro blocks, ie not what you described previously as a B-frame. Therefore, these (new) B-frames a very different weight than those from MPEG2 times.
The extent that such information is not comparable with the MPEG2 GOP.
