Alright, I'm looking at the SW sample, and I don't see the crazy amount of temporal artifacts that the 720 mkv had, but it also looks less detailed than I remember the 480 mkv being (sorry, at work and can't compare). Anyway, the fine (good) grain seems to be gone and the big (some may argue ugly) grain seems to still be there. So, why bother?

I've tried to take into account what you said about the detail and the grain. When you have time would you look at this? If you don't think it's an improvement I think I will concede with you and just release a 480p anamorphic version with only adjusted levels and saturation alongside the 480p raw letterbox.

It's the same method in the script above but I've added some masks and a couple other things to try and keep detail. I might have cheated a bit, I'm not sure. I'll wait to see what you say.

It's a split down the middle of the frame comparison of the raw capture on the right and the filtered version on the left.
