At its base, temporal keyframe interpolation seems like a tricky concept to grasp. There are some big words that may cause you to lose faith — but fear not, it’s actually quite simple. Taken out of context, “interpolation” is a wordy definition.

In the mathematical field of numerical analysis, interpolation is a method of constructing new data points within the range of a discrete set of known data points.

But in the context of motion in After Effects, it’s basically just how the data in your motion is understood and executed. You may have two points (keyframes) in a movement, but your computer is calculating many more points in between the two, like motion, speed, and blur.

There are several facets of working with keyframes and various interpolations in After Effects. It’s important to understand how the keyframes animate, how to ease the keyframes in and out, as well as explore different interpolation methods. The below tutorial by Dan Stevers is a great place to start.

Basics of Keyframe Interpolation

The science behind keyframe interpolation is a little trickier — especially if you’re looking into how it’s automated. If you’re interested in how to get the most out of temporal keyframe interpolation, the video below (from VideoFort) is a great resource.

The same concepts carry over into other programs as well. If you’re looking to smooth your keyframe animations in say, Adobe Premiere Pro, the same science and terminology carries over. You can use the “Ease In” and “Ease Out” tricks for temporal keyframe interpolation. Here’s a tutorial from Tony Lee Glenn for working in Premiere Pro.
