How to Adjust Keyframe Interpolation in Cinema 4D

Dazzle Ship - Drone Racing League

Have you noticed how, when you record an object going from A to B in Cinema 4D, the object speeds up at the start and slows down at the end? That's Cinema 4D's default keyframe interpolation at work. Cinema 4D eases the motion in at the start, and eases it out at the end, to avoid an abrupt transition.

That is all well and good, but what if you want an object come to a grinding halt? Or to travel at the same speed throughout?

This is when you need to dive into F-Curves (Function-Curves). These give you full control over how Cinema 4D interpolates (works out) the values between keyframes. In other words, you can adjust how the animation changes between keyframes by editing the F-Curve. This is quick and easy to do once you get the hang of it.

One definition of "interpolation" is 'the introduction of something between other things.' We tell Cinema 4D the "key" positions of the object by recording keyframes, and Cinema 4D takes care of the in-between positions (values) for us, referencing the F-Curve.

How to Adjust Keyframe Interpolation in Cinema 4D

In this tutorial, you'll learn how to adjust keyframe interpolation in Cinema 4D - i.e. how to control what happens to an object's animation between the keyframes. By default, Cinema 4D applies ease-in and ease-out to the motion of objects, meaning that they will speed up at the start and then slow down at the end. You can change this by adjusting an F-Curve (Function-Curve).

First, you'll have a quick run-through of how to record keyframes in Cinema 4D. Then you'll access the F-Curve, which controls the animation between the keyframes.

You'll adjust the F-Curve to radically alter away from the default ease-in and ease-out, such as to get an object to move at constant speed.
