here with a lifetime's worth of accumulated frame rate wisdom. the reason wheels on car commercial TV ads seem like they are spinning in reverse is because the camera only records at a certain (slower) frame rate. and so, the wheels aren't captured moving as they would in real life. so they appear to be spinning backwards.



TVs and computer monitors get that awful glowy flickering effect on camera because a computer shoots out images in rapid fire frames. we can't see the frame rate change but our eyes can. and since they are being constantly bombarded by flickering images (alternating between light and dark), they ache. forcing us to rub our eyes in frustration.



this is also the same reason that when you watch movies at home in complete darkness, your eyes will get tired. without another light source, the same flickering effect from the TV will cause our eyes to become irritated. this doesn't happen in movie theatres because film has a consistent frame rate flow. enabling us to watch a whole movie in complete darkness. and not hurt our eyes. the moral of the story: turn on another light source when you watch movies at home. it ruins the mood but in the long run, it saves you from a big headache two hours later.



some of these "facts" could be wrong. sue me.
