ADOBE PREMIERE PRO CS3 283 User Guide • Like the Timeline panel, the Effect Controls panel also displays keyframes graphically. Once keyframing is activated for an effect property, you can display the Value and Velocity graphs. The Value graph displays keyframes with changes in an effect's property values. The Velocity graph displays keyframes with handles for adjusting the speed and smoothness of the value changes from keyframe to keyframe. • Keyframes for audio track effects can be edited only in the Timeline panel or in the Audio Mixer. Keyframes for audio clip effects are like keyframes for video clip effects; they can be edited in the Timeline panel or in the Effect Controls panel. You can modify the panel arrangement further and choose Window > Workspace > New Workspace to save the modified configuration as your own workspace. Be sure to give your workspace a name in the New Workspace dialog box before clicking the Save button. See also "Activate keyframing" on page 286 "About recording audio changes" on page 206 View keyframes and graphs Both the Effect Controls and the Timeline panels let you adjust the timing and values of keyframes, but each works in a different way. Whereas the Effect Controls panel displays all effect properties, keyframes, and interpolation methods at once, clips in the Timeline panel can show only one effect property at a time. In the Effect Controls panel, you have complete control over keyframe values. In the Timeline panel, you have limited control (for example, you can't change values that use x, y coordinates, such as Position), however, you can make keyframe adjustments while editing without moving to the Effect Controls panel. The graphs in the Timeline and Effect Controls panels display the values of each keyframe and the interpolated values between keyframes. When the graph of an effect property is level, the value of the property is unchanged between keyframes. When the graph goes up or down, the value of a property increases or decreases between keyframes. You can change the interpolation method and adjust Bezier curves in a graph to affect the speed and smoothness of the property changes from one keyframe to the next. See also "Working with keyframes" on page 282 "Edit keyframe graphs" on page 289 View keyframes in the Effect Controls panel If you've added keyframes to a sequence clip, you can view them in the Effect Controls panel. Any effect containing keyframed properties displays Summary Keyframe icons when the effect is collapsed. Summary keyframes appear across from the effect's heading and correspond to all the individual property keyframes contained in the effect. You cannot manipulate summary keyframes; they appear for reference only. 1 Select a clip in the Timeline panel. 2 If necessary, click the Show/Hide Timeline View button in the Effect Controls panel to show the effects timeline. You may need to widen the Effect Controls panel to make the Show/Hide Timeline View button visible. 3 In the Effect Controls panel, click the triangle to the left of the effect name to expand the effect you want to view. The keyframes display in the Effect Controls timeline. April 1, 2008
