Edit keyframe graphs



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 a Timeline panel while monitoring these changes in the Velocity and Value graphs in the Effect Controls panel.

Edit keyframe graphs in the Effect Controls panel

Once 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 property 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.

Effect property’s value and velocity graphs

A.
Keyframe marker

B.
Level graph indicating unchanged value

C.
Rising graph indicating increasing value

D.
Falling graph indicating decreasing value

E.
Keyframe

F.
Value graph

G.
Velocity graph

  1. In a Timeline panel, select a clip containing an effect containing keyframes you want to adjust.
  2. In the Effect Controls panel, click the triangle to expand the controls for the effect.
  3. Click the triangle next to a property’s name to display its Value and Velocity graphs.
    Note: If no keyframes have been added, the graphs appear as flat lines.
  4. (Optional) To better view a graph, hover the Selection or Pen tool over the boundary line below a graph until the pointer turns into a segment pointer  , and then drag to increase the height of the graph area.
  5. Use the Selection or Pen tool to drag a keyframe up or down on the Value graph, changing the effect property’s value.
    Note: In a Value or Velocity graph, you cannot move a keyframe left or right to change its current time. Instead, drag a keyframe marker above the graph using the Selection or Pen tool.

Edit keyframe graphs from a Timeline panel

  1. Make sure a Timeline panel has at least one clip containing one or more effects with keyframes. Select this clip and select the Effect Controls panel.
  2. Make sure that the keyframes for the clip or track are visible in a Timeline panel.
  3. In the Effect Controls panel, click the triangle next to the control you want to adjust to expose its Value and Velocity graphs.
  4. In the effect menu that appears after the name of the clip or track, select the property you want to adjust. If you can’t see the effect menu, try increasing the magnification of a Timeline panel.
  5. Use the Selection or Pen tool to do one of the following:

    • If you want to edit multiple or nonadjacent keyframes, select those keyframes.

    • Position the Selection or Pen tool over a keyframe or keyframe segment. The Selection or Pen tool changes to the keyframe pointer  or keyframe segment pointer  .

  6. Do any combination of the following:

    • Drag a keyframe or segment up or down to change the value. As you drag, a tool tip indicates the current value. If no keyframes are present, dragging adjusts the value for the entire clip or track.

    • Drag a keyframe left or right to change the time location of the keyframe. As you drag, a tool tip indicates the current time. If you move a keyframe onto another keyframe, the new keyframe replaces the old one.

    The Value and Velocity graphs in the Effect Controls panel will show changes made to keyframes in a Timeline panel.
