Based on some tests I guess prefiltering is a gimmick lol, aside so many filtering conventions sticked to our brains for so long (like blocksize 16 for 1080p). Thanks for the tool it takes some of the voodoo-guessing out of the equation. I think implementing VMAF is worth here, after reading the Netflix VMAF article a few weeks ago it seemed that SSIM did some bad assumptions, in my case contrasharpening was defaulting to 0 or false which in my opinion wasn't making justice to what I observed. That or if your port it I might start using VapourSynth occasionally for VMAF and BM3D, I just don't like how it requires you to write more, and script readability. Also something for x264 like SSIM Plus would be cool if someone knows about a free open source alternative.
