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.

Media quality is not a major issue on the internet, as long as the gap is small (it's the case here). Licensing quality is one.

Remember the Unisys episode : GIF was certainly superior to JPEG in its time about compression ratio vs quality...

I think you should compare gif to png. That's more inline with the usage pattern.

Yes, but as far as I know PNG did not exist at that time. GIF was a superior format on the 256-color screens in term of compression vs image quality, but JPEG was safer.

(True, PNG beats them all, I use this format for just about everything which doesn't require layers or animation ^^ But at the time, there was a compromise about compression quality vs licensing quality)

PNG was created when patent fears about GIF began to seem reasonable. It is not reasonable to compare PNG and GIF therefore because for many years there was no such option; the choices were JPEG and GIF, or to take a chance that the client would support some other format and have the bandwidth to download it.

PNG is superior to GIF in almost every way. It does not animate and under certain very specific scenarios has inferior compression. Other than those it is superior.

PNG is superior to JPEG in image quality, being lossless, but for photographic imagery compresses much less well.

Today GIF is used almost exclusively for its animations, since no other means of animation is natively supported by all browsers.

You could't be more wrong. Comparing GIF to JPEG is slightly more meaningful than comparing MP3 to DivX, they are two different formats intended for different purposes.

Gif is a lossless 8-bit (usually) color indexed format that is great for simple computer graphics and illustrations. JPEG is a lossly (with exceptions) 24-bit format that is great for photographs but terrible for illustrations.

I know what GIF is. However, let's go back to those times. When you were making an average personal website (that looked horrible), if you wanted to put a little graphic as a button, you had two choices :
-> Gif (smaller file size in most cases, pretty close to the original file, supports animation)
-> JPEG (big or ugly, no animation)

So GIF was the superior format for most little images on the web. JPEG is good for photographs, but it can also be used for illustrations, even though it does a terrible job. And it became used so in the time where Unisys went amok.
