How to make expressions only work within certain parameters?
on Sep 2, 2010 at 12:05:21 pm

I hope my subject line makes sense to people, I can only think how to explain by example. I want to use some keyframes generated by some audio to drive an after effects comp, but I only want to use the keyframes within a certain value range. In this case not the quietest and not the loudest. But, I have NO idea how to tell an expression to ignore a value below or above a particular level. Any ideas?

Any comments appreciated :o)
