Continuous Bezier interpolation

Like Auto Bezier interpolation, Continuous Bezier interpolation creates a smooth rate of change through a keyframe. However, you set the positions of Continuous Bezier direction handles manually. Adjustments you make change the shape of the Value graph or motion path segments on either side of the keyframe.

If you apply Continuous Bezier spatial interpolation to all keyframes of a motion path, After Effects adjusts the motion path at each keyframe to create a smooth transition at each keyframe. As with temporal properties, After Effects maintains these smooth transitions as you move a Continuous Bezier keyframe on the motion path. The speed of motion along the path is controlled by the temporal interpolation applied at each keyframe.
