Theora bypasses H.264 for quality
Over the past year, Xiph hackers have spent a lot of effort on improving the free Theora video codec, and succeeded - the latest version of Theora bypassed the H.264 codec according to the results of the PSNR objective quality tests (chart below).
This is a very important achievement, because the H.264 codec has recently become very widespread and has practically captured the market for the distribution of video content. At the same time, it is a closed commercial standard that is only temporarily free. Already in 2010, the owners of this format are planning to start charging millions of dollars for its use. Device manufacturers will deduct $ 0.20 per player. Website owners will take $ 0.02 per file, or 2% of the cost of the content, if the video’s duration exceeds 12 minutes.
Theora is the only free analogue of this commercial standard and the only free alternative that is not inferior in compression quality.
On the X axis, the stream is in kbps, on the Y axis, the PSNR level is in dB.
