Edit a keyframe in the Graph Editor

A value graph in the Graph Editor displays the values for each keyframe and the interpolated values between keyframes. When the value graph of a layer property is level, the value of the property is unchanged between keyframes. When the value graph goes up or down, the value of a layer property increases or decreases between keyframes.

Value graph 

A.
Keyframe.

B.
A level value graph indicates unchanging values.

C.
A rising graph indicates increasing values.

D.
A falling graph indicates decreasing values.

You can change layer property values by moving the points (keyframes) on the value graph up or down. For example, you can increase the value of a Rotation keyframe by dragging the keyframe’s marker on the Rotation property’s value graph higher up on the graph.

Note: Values for the Anchor Point, Mask Path, effect control points, 3D Orientation, and Position properties are spatial, so they use speed graphs by default instead of value graphs.
  1. In the Timeline panel, show a temporal property for a layer.
  2. If necessary, click the Graph Editor button or press Shift+F3 to enter Graph Editor mode.
  3. If necessary, add a keyframe at the point in time you want the change to occur.
  4. Drag the keyframe up or down to set a new value for the layer property.
