When you're the creator of the animation, you can directly simulate motion blur instead of using temporal downsampling. The smoothness of video depends on the angular distance objects move in your field of view between frames. You can see this in the demos: the lower framerates are relatively smooth at the ends of the animation where the motion is slowest, and all framerates (even the highest) become considerably smoother when you decrease your browser zoom.
