It improves the\ncompression efficiency. Tested in speed 1, the coding gains are\n\n            avg PSNR     ovr PSNR     SSIM\nlowres      -0.109   \t -0.099\t     -0.293\nugc360p     -0.106\t -0.203\t     -0.223\nmidres      -0.300\t -0.319\t     -0.418\nhdres       -0.317\t -0.344\t     -0.447\n\nThe encoding speed goes down temporarily.
