Those effects are known, and mostly resolved.

Malcom: The detail loss is because too much structure may get lost during the 1st (not MC'ed) gaussian stage. (BTW, it wasn't only the pole ... also much of those little waves on the water were smeared away.)
=> Solved, by giving a bit more bias towards the original.

LaTo/2BDecided: What you're seeing there is MVTools when it actually misses scenechanges. (Light flashes can be considered as such, in this context).
=> Probably solved, by lowering SAD thresholds in some MVTools-filters.

(I hope it'll work out reliably enough ... generally, SAD is only a rough (and relatively poor) measurement: in high detail/high contrast areas, even related blocks can have a rather big SAD, whereas in low detail/low contrast areas, even unrelated blocks may have a rather low SAD. Well, what to do. SAD really is not a versatile measure, still in MVTools it is *THE* decisive element. TempGaussMC actually has to play one or two severe tricks to sail around the darn SAD cliffs...)
