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.

The http://www.quavlive.com/video_codec_comparison has been updated, and VP8 is as good (or, maybe, as bad) as h264 encoded with the libx264 (is it x264?) on a visually complex video. The bitrate of the output is different from the one entered in command line (rounding?), and is always lower with VP8. Also, the size of the video file is always smaller with VP8. Both are beneficial for streaming.

Notice that the x264 video done by quAVlive, on the same video "park joy", is noticeably worse than the ones done by the x264 dev Dark Shiraki:
