In the Effect Controls panel, you can make adjustments to keyframes for any effect property by editing their graphs. Alternately, you can make adjustments to effect keyframes in the Timeline panel while monitoring these changes in the Velocity and Value graphs in the Effect Controls panel.
Edit keyframe graphs in the Effect Controls panelOnce you activate keyframing for an effect’s property, you can display the effect’s Value and Velocity graphs. Value graphs provide information about the value of nonspatial keyframes (such as the Scale parameter of the Motion effect) at any point in time. They also display and let you adjust the interpolation between keyframes. You can use the Velocity graph to fine‑tune the rate of change between keyframes.
