I couldn't find any x264 tune ssim encodes, but I did find some x265 tune PSNR that show basically the same pattern. Tuning for PSNR at the expense of Fast SSIM, while other metrics don't really change.
The major difference is that the PSNR tuning seems to help with CB and Cr for x265, not just the Y channel. Fascinating. So it appears x264 and x265 have their own version of VMAF which is just the combination of PSNR and FastSSIM metrics. |
