Many older/commercial video codecs optimized for PSNR, which results in the output being blurry and textureless because that's the best way to minimize rate for the same PSNR.
Even with that, showing H.265 having lower PSNR than H.264 is odd --- it's the former which has often looked blurrier to me.

- kookamamie 3y agoAt equal bitrate H.265 typically is considered twice as efficient as H.264. The graphs look all wrong to me - they show "ours" at a lower PNSR compared to both H.264 and H.265.
