2. There's some halos around the edges; try YAHR() to reduce them. If you find YAHR's strength a bit too high (losing details), try increase sharpening first and stop right before the halos appear again. If you don't like to result, you may want to use supersampling. Anyway, you'll see what YAHR() does and if it improves your video or not. Probably yes.

Already tried most of what you have proposed. The problem with YAHR (and to some extent even better de-haloers) is that they kill corners and small lines, and leave the video with a soapy, artificial look. One of Didee's poorest products IMHO. I'd be interested in looking at some specific examples if you want to actually try them on the GOUT and post what configuration works for you.

Well, now I've tried EVERYTHING you suggested. Yahr by itself rounds all corners. If you run it on the opening scroll, it becomes almost unreadable. It also kills a lot of stars. Anything that ruins the image this much is not useable.

Tried (apprehensively) with pre-sharpening. Pre-sharpening is usually a bad idea, better to post contra sharpen. Tried both, but neither improved the result enough.

There was one method using YAHR that had some promise.

source = last
med = MT_luts(source,source,mode="med",pixels="0 1 0 0 0 -1",expr="y")
Median1(source,med,source.YAHR(),chroma="copy first")

Killed the halos, with much less artifacting. BUT, the crawl was still too aweful. If it kills the crawl, it'll kill something else that I care about too. No go.

Tried using supersampling. Doubled the image size and it still destroyed some detail, but it also didn't remove halos at all.
