Benchmarks Now that Google has opened up VP8, the big question is obviously how it'll hold up to H264. Of course, VP8 already wins by default because it's open source and royalty free, but that doesn't mean we should neglect the quality issue. Jan Ozer from StreamingMedia.com has put up an article comparing the two codecs, and concludes that the differences are negligible - in fact, only in some high-motion videos did H264 win out. As always, this is just one comparison and most certainly anything but conclusive. Update: Another comparison. I can't spot the difference, but then again, I'm no expert.

They are different codecs

I just gave a quick look to the "Park Joy" videos (the videos themselves and not the still images) on the quavlive link. My conclusions:

- h.264 has a lot more artifacts than VP8;
- on still screenshots, h.264 wins in all cases;
- on (almost) all resolutions (in motion), both codecs seemed the same;
- the exception was SD video, which seemed strange in h.264 and more "natural" in VP8.

At least it is my opinion, but who cares? Here is my opinion about the much more interesting topic of the codecs themselves:

- The visual output of each one is incredibly different on low framerates;
- Yet, both are able to reproduce the intended image!
- So, they are not comparable;
- This happens because for us to compare them, we would need an objective way of deciding which are good and bad losses.
- We don't have that.
- So, opinions on how close to reality it gets will vary from person to person.

At least it is my opinion... on something much more interesting than a boring comparison of different moving images.

Exactly. People actually see motion as blur. There is no real point in precise sharp definition for parts of the video which are in high motion ... people are going to see it as blur anyway.

These observations also highlight that there are major differences in approach between h.264 and VP8. The codecs use distinctly different methods to achieve the same end (compression of digital video data). Ergo, one would surmise that these codecs do not infringe on one another's patents.
