Using the Value graph to change a layer property value
The Timeline window 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 a layer
property is unchanged between keyframes. When the Value graph goes up or down, the
value of a layer property increases or decreases between keyframes.

A. A level value graph indicates unchanging values. B. A rising graph indicates
increasing values. C. A falling graph indicates decreasing values.
You can change layer property values by moving the points on the Value graph up or
down. For example, you can increase a Rotation keyframe's value by dragging a point on
the Rotation property's Value graph higher up the graph.
Note: Values for the Anchor Point, Mask Shape, Effect point controls, 3D Orientation, and
Position properties are spatial, so they are graphically represented in the Composition
window, not in the Value graph in the Timeline window.
To change the value of a layer property:
1 In the Timeline window, display the property for a layer.
2 To change the marker at the current time, do one of the following:
Click the underlined value and type a new value.
•
Position the pointer over the underlined value and drag to change the value; hold
•
down Shift to drag using greater increments (in multiples of 10).
Click the triangle next to the property name to display the Value graph, and then drag a
•
value marker up or down.
3 To change the value of a keyframe at any time, double-click the keyframe icon to type a
different value.
To see the new value displayed next to the property name, position the current-time
marker on the keyframe.
Adding keyframes to a Value graph
The pen tools provide the most flexible way to change temporal properties in the Value
graph or a motion path. Editing with the pen tool is similar to modifying a path in a
drawing application such as Adobe Illustrator. For more information on using the pen
tools, see "Drawing a Bezier mask with the pen tool" on page 152.
