The first in-depth technical analysis of VP8

May 20, 2010, 14:32 (0 Talkback[s])

"Back in my original post about Internet video, I made some initial comments on the hope that VP8 would solve the problems of web video by providing a supposed patent-free video format with significantly better compression than the current options of Theora and Dirac. Fortunately, it seems I was able to acquire access to the VP8 spec, software, and source a good few days before the official release and so was able to perform a detailed technical analysis in time for the official release.

"The questions I will try to answer here are:

"1. How good is VP8? Is the file format actually better than H.264 in terms of compression, and could a good VP8 encoder beat x264? On2 claimed 50% better than H.264, but On2 has always made absurd claims that they were never able to back up with results, so such a number is almost surely wrong. VP7, for example, was claimed to be 15% better than H.264 while being much faster, but was in reality neither faster nor higher quality."
