724 Part IX Effects
To add more keyframes:
1 Move the playhead to another point in the clip where you want to set a keyframe.
2 Do one of the following:
 Adjust the appropriate setting control.
 Type a number in the appropriate number field.
 Hold down the Option key and click a clip’s overlay in the Timeline where you want
to add the keyframe.
This doesn’t change the parameter’s current value; it simply adds a keyframe with the
same value. You can add as many keyframes as you want by clicking repeatedly with
the Option key held down.
Adjusting and Deleting Keyframes
After you add keyframes to a parameter, you can adjust keyframes to produce the desired
effect. You can modify individual keyframes, interpolated values between keyframes, or all
keyframes at one time. You can also move and delete keyframes at any time.
To adjust the value of a single keyframe, do one of the following:
m Move the playhead to the keyframe you want to adjust, then drag the appropriate
setting control to a new value.
m Move the playhead to the keyframe you want to adjust, type a new value in the
appropriate parameter’s number field, then press Return.
m Move the pointer over the keyframe you want to modify (it becomes a crosshair), then
drag the keyframe up or down.
 To raise the keyframe’s value, drag the keyframe up.
 To lower the keyframe’s value, drag the keyframe down.
To adjust a parameter value between two keyframes:
m Move the pointer over the section of the parameter’s keyframe graph line (the pointer
turns into the Adjust Line Segment pointer), then drag that area up or down to modify it.
Note: The keyframes on either side of the adjusted section are changed simultaneously.
