If memory serves me right (always a gamble with me...). A  "Key Frame Rate"
is a method of creating variable animation speeds in an animation. For
example, lets you have 3 key frames (A, B, C) and 30 frames. From frame A to
B you have 20 frames and from B to C you have 10 frames. So when you play If
the "key frame rate" is 3 key frames a sec, then  animation will play faster
over A to B, than it will from B to C. Because A-B has more frames to play
in the same time as B-C...

I hope this is right because it has been a couple of years since I read
anything on the subject, let alone done anything with it....


I hope that helps
