Parameter Changes at Keyframes
How an effect parameter changes at a keyframe is governed by which keyframe interpolation option you select. Interpolation refers to the method the Avid editing application uses to calculate the rate of change and the relative smoothness of change.
To select an interpolation option:
  Right-click (Windows) or Ctrl+Shift+click (Macintosh) the keyframe graph or keyframe track for the parameter with which you are working, and select one of the following:
–   Shelf
–   Linear
–   Spline
–   BΘzier
Each option is described in Options for Controlling Parameter Changes at Keyframes.
