Have you tried stepping through the footage frame by frame in a section with motion?  This can reveal footage that was converted from 23.976 to 29.97p, for example, by noting that the cadence is 12344, 12344... - every fourth frame repeated for one frame.  That can give it a jerky look.

I’ve encountered this several times.  I put it in an NLE, and manually remove every fourth frame.  The result is a shorter clip, but at least it smooths out the motion.

Obviously, this would present problems with audio.  But, you could take address that with some time-remapping.
