Animation question: exposures on "eights" or "twelves"

[superboyac]

So I've been studying animation, and perhaps I missed something as I was going through this one book...but maybe someone here can clarify my question.  Here's the passage in question:
Animation question: exposures on "eights" or "twelves"

I just want to make sure I'm understanding this correctly.  The only reason why I'm particularly interested is because I also have noticed that I like the Tom and Jerry timing more so than other similar cartoons. 

So...when he says people are walking on "twelve exposures" or "eights", as far as actual time units go [seconds], does that mean (for the 8 example):
cartoons are 24 fps
so 8/24 = 0.3 seconds

is he saying each step takes 0.3 seconds?  Or every two steps (one cycle) takes 0.3 seconds?  I don't quite get it.  It seems like a brisk pace either way.

Well, i was right in that I did miss something (the page before)! 


So my assumption was also correct...it's just a division of the framerate.  Which also reveals a very fascinating nugget to me regarding these master animators.  They ARE quite anal!  his whole brain/body is finely tuned to this kind of specific timing, sheesh.  I love learning things like this because occasionally I'll be made to feel uncomfortable or awkward about my attention to detail.

And interestingly enough, when you translate this rhythm to musical notation (bpm), it is:
twelves = 120 bpm
eights = 180 bpm

Always good to know!  I've always said the natural rhythm I tend to prefer is about 75 bpm.  Cuz I'm all relaxed like that.  West Coast style, yo.

Be my guest. I'm bored with the stuff I already know.
