Sergei from Ukramedia has created a Bounce and Drop AE preset that easily adds a bit of wiggle and wobble to your graphics. And it’s free!
The Bounce and Drop preset allows for keyframeable adjustments to position, scale, rotation and opacity. You can adjust them separately, or use the global inertial bounce to affect them all at once. You can also adjust the amplitude, frequency and decay of the bounce or drop effect.
While Sergei is offering the preset for free, he does ask that you show a little love by either liking him on Facebook or following him on Twitter to get it.
