GreyScaleGorilla (GSG) has a video online showing the #1 rookie mistake in Adobe AfterEffects, and how to fix it.  What’s the problem? “Wobbly Keyframes”.

The actual problem is that, by default, AfterEffects uses Bezier interpolation for animation keyframes based on positions, so if you attempt to freeze something for a few frames by cloning a keyframe at 2 points, you wind up with an overshoot and bounce as it attempts to smoothly interpolate the motion.

Video included after the break.
