How do I remove Moire patterns from defishing?
#13
-- removed unnecessary full quote; by Selur ---
I'm taking about the Moire artifact in the blue sky. Looking at the pixel level, it has a comb pattern on the sides, about a quarter of the frame. when the player window is scaled, it's a very noticeable, blocky Moire pattern, not quite Fraunhoffer lines. When the defishing is applied, the pixels are distorted within Mercalli to make the frame look normal. Something Mercalli is doing makes this pattern.

After I applied my filter pipeline, is smooths it out pretty good, most of the time, along with the degrain that I need.

I scaled using Hybrid's viewer to 2x, to test before and after, with each filter, until getting the cleanest result. 
I just tried the 10 bit, and the filter is very clean, and seems to have worked in one pass, but do I need all of those 4 filters now? I hope to speed it up.

I can't find what you mean, LumaMask, which filter.
