i did quite extensive tests after the last discussion, and
found that cubic is a rather poor filter for my kind of work
(scanned film stock) and my taste.
i personally really, *really* miss the "sinc" filter in
shake, specially for downscaling - i found no way i could
get the same results as easy in nuke (even after different
sharpening methods).
also lanczos was very nice, and so was mitchell (btw, beware
that mitchell is softer in nuke, and destructive even on
integer numbers!)
personally i defaulted to "keys" as my standard filter in
nuke, since it gave me the best tradeoff, but maybe we can
add a feature request for sinc? or is this a protected
algorithm?
i understand that for other type of footage (GCI?) cubic
might be nice, but for grainy stuff i really dislike the
pattern... adding a blur is not an option because it will
loose detail that cant be recovered (compared to sinc or
even lanczos).

This has been discussed before and it's apparently correct -
however Shake used to hide it from you.
Try a 1 pixel blur before the transform might fix it but give
you a slightly softer shake style transform
If memory serves me right...
