It should move smoothly with the motion of all images. If it does not, the whole effect is dragged down. The sound should not overwhelm what is seen. The eye is not the only instrument that is slowed down when care is not used in programming. Computers tend to bog down and the motion can drag if attention is not paid to detail.
Presentations become jerky.
The motion is just like Max Headroom. It is all I can think of when I see them. The stops and starts usually distract me to the point that interest is lost in the initial wonder of the presentation itself. It doesn't overwhelm me with too much visual information too fast. It moves smoothly as if it were alive.
