Thought you meant that, but wasn't sure.

I definitely wouldn't leave "high" on by default, except maybe for Anime content. But did you find "low" to eat away details, too? I would like to have a setting which is low enough to never harm, but to sometimes help. Is the current "low" setting still too agressive for that? I guess I could rename the current "low" setting to "medium" and add a "low" setting which is even more careful. Such a "low" setting probably wouldn't really remove ugly banding artifacts, but it could at least smooth the rough edges away from clean non-dithered 8bit encodes.

With some content it may eliminate a lot of the banding/macroblocking, but actually look worse, because what's left now stands out against an otherwise clean image, and is a distraction.

Yeah. We humans have such a big advantage because we know what a fingernail is supposed to look like. So we know which part of the image is real detail and which is an artifact. A simple debanding algorithm has no way of knowing that. So at least in "high" mode it's always a balance act between debanding and detail removal. I do think in "low" mode usually details are left well enough alive.

Hmmmm... Yes, that one is a bit surprising. I'll have a look at that later when I find some time.
