persistance of vision
so, if you're cat-type curious, you can go to the wikipedia page and read up on persistance of vision.
it's basically when there is such a small change and it happens quick enough that you're eye has trouble catching the space in between, said picture appears to be moving. let's see... examples:
1. film. it's thousands of images one after another in such a rapid susession, it appears to be constantly moving.
2. zoetrope (if done properly, unlike mine).
3. flip books (which is our new class project).
4. OH! the whole, pull the cloth off the table trick? it's done so quickly (so that nothing moves) and just appears to be there one second and not there the next (maybe?).
okay, so i thought this was pretty nifty and figured i'd share. the frames per second (fps) is just that, the amount of frames that are shown each second.
-if it's below 16fps, the eye doesn't view it as steady movement
- film at movie theaters run at 24fps
- video in usa&japan records at 60fps (50fps in "eurasia")
this part's long... but it's the best part:
"In drawn animation, moving characters are often shot "on twos", that is to say, one drawing is shown for every two frames of film (which usually runs at 24 frames per second), meaning there are only 12 drawings per second. Even though the image update rate is low, the fluidity is satisfactory for most subjects. However, when a character is required to perform a quick movement, it is usually necessary to revert to animating "on ones", as "twos" are too slow to convey the motion adequately. A blend of the two techniques keeps the eye fooled without unnecessary production cost.
Animation for most "Saturday morning cartoons" is produced as cheaply as possible, and is most often shot on "threes", or even "fours", i.e. three or four frames per drawing. This translates to only 8 or 6 drawings per second."
