- This has a very simple explanation. When you shoot traditional
- film (at 24 fps) or video (50/60 half-frames/s (PAL/NTSC)) you
- get pretty much motion-blur on the objects that move. This makes
- the motion look a whole lot smoother. Computer animations on the
- contrary often consist of distinc pictures, which make them look
- shakier. Unless you're raytracing your anim and use motionblur in
- it, it will look much less smooth - try pause a video and see how
- sharp the picture actually is. :-) It's thanks to the motion video
- still offers an experience of acceptable picture-quality.
- When it comes to how many fps the human eye can see, the rate is
- actually down at 10-12 fps (*), meaning that above that, the eye
- can no longer see the _individual_ pictures - the movement may still
- look bad as "%&%ñ&/, but you cannot correctly discriminate between
- consecutive frames.
-
- (*) according to several books on cartoon animation.
