inverted scale expression
I’m sure this is fairly elementary as far as expressions go but right now I just need the fish!
I need an expression that inverts the scale value. That is, starting with 100% = 100%, 99% would equal 101%, 90% would equal 110%, etc.
Thanks!

I’m no expression guru so I’m sure there is another solution out there, but why not have both of your scales driven by a seperate thing. Create a null object and apply a slider to it.
Then, on each one have it be their scale + the slider and on one of them add *-1 (put theslider *-1in parentheses).
Then when the slider goes to 1, one of the layers will be plus one and the other would be minus one.But, that’s just one solution, I’m sure there are several others.
Also, just for future reference, there’s actually a dedicated After Effects Expressions Forum here on the COW.

Michael, thanks for your response. I will try your solution, as well as wonder over to the expressions forum.
