Not meaning to be nitpicky, but I believe your numbers may be a little off in your recent ask. While 2D western animation is shot at 24FPS, most Disney-level animation is animated on 2s, or 12FPS, with occasional 1s (24FPS) on fast motions. I don't think anyone except Richard Williams has ever made a serious attempt to animate all 24 frames in a second, since that's quite a bit more than the human eye can see! Unless I'm missing something....
Ah, no, you’re right. I mis-spoke (mis-typed?).
Shot at 24 FPS, animated at much lower. However, my point about in-betweens still stands.
Also, humans can actually recognize up to 60 fps. Anything past that is negligible. 24 fps was chosen for film because it had the best ratio between quality and cost. Video is 30 fps and some new films (Like the Hobbit) are being shot at even higher.
hi! what are the white flashes in pencil tests? looks as if there are blank sheets inserted between drawings... but why?
What you’re talking about is probably a placeholder for an inbetween drawing which wasn’t done yet at the time the test was made.
Animators usually only draw between 12 and 16 frames per second, depending on the needs of the shot. The final animation is shot at 24 frames per second. Those extra drawings are done by an assistant, and they’re called “inbetweens.”
For any of you computer animators out there, this is where the term “tween” comes from. That’s the program filling in those drawings for you.
