Deband

Sapphire’s Deband filter removes banding artifacts from a clip by diffusing pixels across the banded areas, while keeping the original edges intact. To use this effect, first select Show:Edges and adjust the edge threshold until the banding edges just disappear, leaving only the desired real edges. Then select Show:Result to see the result. If you still see some banding, increase Diffuse Threshold and/or Diffuse Radius.
