Do you really think you see and visualize motion constantly. Perhaps you
should spend a little more time around and airport yourself. Many
propellers, especially the large diameter props found on radial engines,
will appear at times to be rotating slower, or backwards. It's a fainter
image than recorded on film, but the partnership of the human eye and brain
does not realize fluid motion.

This is completely incorrect. Human vision produces no such artifact.
Anything moving beyond a certain speed is simply a blur; it never appears to
move backwards.

Motion pictures captured on film greatly exaggerates the phenomenon.

No, motion pictures PRODUCE the phenomenon. It's an artifact of the motion
picture, not human vision.

Some of the new video equipment will seem to even stop a prop to the
extent it's distracting to the quality of the recording.

That is a function of shutter speed.

But the human visual system well do so as well, just to a much lesser extent.

No, the human visual system will not do it at all.
