Keyframe Interpolation

The interpolation method that a keyframe is set to determines how settings are animated from one keyframe to the next. There are three possible types of interpolation:

By default, all new keyframes that you create are smooth, although you can change a keyframe's interpolation at any time. Changing a keyframe's interpolation affects only the way values are animated between it and the next keyframe to the right.

To change a keyframe's interpolation
  1. Move the playhead to the keyframe you want to change.

  2. Choose Timeline > Change Keyframe (or press Control-8).
