Selecting Interpolation Types

The Graph contains controls allowing you to specify interpolation methods, which can be specified on both the element and frame range levels. The Interpolation controls appear as follows:

Interpolation Controls.

To choose an interpolation method, select the elements and frame range to modify, then click your desired Interpolation button. The Animation palette uses color codes to depict varying interpolation methods.

Spline: Green

Splines can sometimes go beyond and exceed the maximum keyframed values depending on the slope created by tightly-spaced keyframes. Adding additional keyframes can constrain the slope into more pleasing levels.

When using Spline Interpolation, be aware that adding frames will affect the previous frames, due to the way the keys are interpolated. Be sure to check your animation graphs for unexpected movements before you render the animation.

Linear: Red. If you are new to animation, we recommend that you start out with Linear Interpolation as it is the easiest to understand.

Constant: Grayed out

Break Spline: A hash mark appears where Break Spline has been applied.
