Initial evaluation of naive implementation of AniMaxx’s algorithm suggests it’s oversharpening in my case. I like the overall output otherwise. Going to adjust some variables, then toss in the rest and see what it looks like.

I am happy to see that a few pointers from my approach worked, but I was actually afraid it would oversharpen in your case. My initial NTSC sharpening approach was enough for that medium, but PAL is softer, so I had to adjust - in your case you will have to reduce.
