Interpolation
Keyframes are specific frames in an animation where control points are set to exact values on a
given parameter. Interpolation is the method used to fill in the unknown values between two
keyframes. Fusion automatically interpolates between two keyframes. However, you may want
to modify the interpolation to achieve a specific style of animation. The Spline Editor includes
several interpolation methods you can choose from using the toolbar.
Interpolation buttons in the toolbar: Smooth, Linear,
Invert, Step In, and Step Out.
Smooth
A smoothed segment provides a gentle keyframe transition in and out of the keyframe by
slightly extending the direction handles on the curve. This slows down the animation as you
pass through the keyframe. To smooth the selected keyframe(s), press Shift-S or click the
toolbar’s Smooth button.
Smooth interpolation between keyframes.
Linear
A linear segment effectively takes the shortest route between two control points, which is a
straight line. To make the selected keyframe(s) linear, press the L key or click the Linear button
in the toolbar.
Linear interpolation between keyframes.
TIP: Invert is used only for non-animated LUT splines, which are currently only
available in the LUT Editor window.
