Have your keyframes ever found themselves bored with the drab, grey predictability of "Ease" and "Easy Ease"? Do they often complain about plain-jane temporal velocity adjustments? And do you select keyframes, apply an ease, then sigh as your layers move with the predicable monotony brought on by the After Effects defaults? Oh, sure, you might get brave and wander over to the Graph Editor now and again to alter the velocities of your items by hand, but really, how often do you just settle for an "Easy Ease In" and call it a day?
Is there a better way?
Thanks to Ian Haigh, there is. Ian was good enough to recently adapt some Flash-based easing equations originally designed by a fellow named Robert Penner, and he's brought them to After Effects. Check it out at his website.
I've tried the script and was very happy with how it all worked. I've now got a one-button solution to not only creating variations on 'eases', but also the opportunity for consistency. I pretty much always go to the graph editor to make my eases 'more extreme', but the trouble is when applied to multiple keyframes across many layers, they're all slightly different. Now I can use this script and all KF's that I apply it to will have the same 'movement personality'.
There are two drawbacks to the script*, both with workarounds. One, it only works on the first two KF's in an a given parameter. The workaround is to apply the script on multiple 'transform' EFFECTS instead of on to multiple keyframes on the 'transform' PARAMETER. And two, you can't view the resulting velocities in the Graph Editor (should you so choose) unless you select the KF's and go to Animation-> Keyframe Assistant-> Convert Expression to Keyframes. But I would surely recommend that you give it a try, I think you'll like it.
*Edit: take a gander at the comments to this post. Ian addresses both of these considerations.
