have no motion blur subsampling when opened in sequencer and rendered through movie queue. If I were too set temporal samples to 32 in the antialiasing settings, the is no gradual movement, then a pop when rendered, it just pops, which results in a frame blended look in the ended frame. If I create a sequence from scrath, I do nto have this problem. Even if all elements form the imported data smith sequence are deleted, and replaced with new geo, the same problem persists.
