For those in the know, what is the right way to test FPS and motion bars? Check that all bars in each clip pan across smoothly vs. jumpy? Or, is it supposed to be judged in a different way?

You're looking for "smooth" consistent even motion. If the bar's movement has intermittent glitches / pauses / hesitations in the motion something isn't working correctly. Obviously though a 24FPS clip won't be as smooth as a 60FPS one.
