Basically a debander with as many of the perks of a bilateral filter that it can afford, and to me Dither_bilateral16 fits the bill very well.

In this case, you want a controlled smoothing of the flat areas with a wide enough distribution to reconstruct gradients, without taking higher detail into account. Plugins for old AviSynth versions and some depreciated plugins can be found here. VS Bilateral works fine for light banding (probably better), but not if it's a source where say, it was post-processed in 8 bit, high depth was rounded rather than dithered, or it's just plain bitstarved. All the more so when the banding is moving It being a good bilateral works to its disadvantage when you need to actually reconstruct most of the gradients. It just sorta softens them, without distributing the color to a wider area, which doesn't seem to change much with stronger sigmaR settings. It doesn't smooth as much along more pronounced banding edges.
