On current project, I consistently want for nearly every type of motion to create a sense of anticipation for the motion which always relates to simple two keyframe motion in the same way. 24 frames before the motion starts, I want to move in the opposite direction by 5% of the total motion, then launch from that point on the first keyframe. Doing so by adding a third keyframe 24 frames before the first, then offsetting the first by 5% works, but it’s a lot of extra keyframes across the entire project, and if I decide later to make some small adjustment across the board like make it 4% instead of 5%, I’d need to change hundreds of keyframes.
Is there any way to just use the basic 2 keyframes, and dial this behavior in automatically through some sort of keyframe interpolation or other means.
