How to do Easing with Expressions?!?

[Darby Edelen]

AE has a few options for easing values in expressions, you can find them in the Interpolation section of the expressions drop down:

ease(i, low, high, x, y);
easeIn(i, low, high, x, y);
easeOut(i, low, high, x, y);

All of these take a first value ‘i’ and vary the return value from ‘x’ to ‘y’ based on the value of ‘i’ relative to ‘low’ and ‘high.’

Here’s an example:

ease(time, 0, 1, 100, 200);

This will return 100 when time is equal to 0, and 200 when time is equal to 1 (one second). The interpolation will not be linear (there is a linear() function for that) but instead will ease in and ease out.

I don’t believe there are any preset functions for more customizable easing of values, however you can create your own functions within AE’s expressions. However, the function has to exist in every expression you want to use it in.

Thanks Darby! I will play around with it and try these out.
