super_search = MSuper(hpad=16,vpad=16)
bv1 = super_search.MAnalyse(isb = true, delta = 1, overlap= 4, lsad=0)
MMask(last, bv1)
Fixed (in my desktop) by prechecking lsad- when it is zero then the resultin lambda is zero as well. Note: vs-mvtools is no different there, no guard. Some time ago they changed int64 calculation to 'double' arithmetic. But there division by zero with 'double' types does not crash, calculation goes on with a "NaN" value https://github.com/dubhater/vapoursynth-mvtools/blob/master/src/PlaneOfBlocks.cpp#L461 Result (in VS-mvtools) Instead of zero they put -2147483648 to lambda
