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.

Are SI units used, or standard computing units? 15000 Kib would be 15360000 bits, giving x264 a 2.4% advantage. OTOH rounding might trump that, I'm didn't download the videos to check the actual bitrates.

AFAIK, bits are always counted in base 10. It's bytes that use powers of 2. Are there any situations where a kilobit is 1024 bits?

Video encoding ALWAYS uses base 10 values. So it's 1000 or 1000000, not 1024 or 1048576.
