there is nothing in the movie maker script (it is surprisingly
simple at its core) that would interfere with the smoothing
settings that you have done for your representation.

also from how trajectory smoothing is implemented, it is
extremely difficult to imagine how that should not work.
there has to be some inconsistency on your side
that results in VMD not doing what you expect because
you actually didn't do it, but thought it was done or
something similar.
