Also, remember that film is recorded at 24 images per second (24fps).
Motion blur is noticeable. With typical 180 degree shutter setting,
exposed image movement and blur is recorded for 1/48th of a second. You
can simulate this (mostly in post) with digital, and it is sometimes
done when multiple medias are joined in a feature piece.
Just another reference point. I would say that this tends to line up
with some of what Steve is pointing to in the temporal domain. By
nature, less blur...
But, yes, there are LOTS of other factors...
