What is the relation between spatial resolution, temporal resolution and velocity, for the perception of movement in time sampled displays like cinema or television?

Spatio-temporal Aliasing (Motion Lecture)
with frame rates low compared to velocity, sampling artifacts become visible.
This means that given a certain spatial resolution, if the patterns move very fast relative to the temporal resolution, the patterns will appear to jitter as they move. This is why they use blurring in direction of motion (e.g., leaving shutter open) can reduce the sampling artifacts.
