Keyframe line

After you add an effect to a clip, the effect appears under the clip in the keyframe line in the Timeline window. When you add more than one effect to a clip, the effect pop-up menu appears at the left edge of the clip. This menu displays each of the applied effects. If the effect has adjustable controls, you can set keyframes for it in the keyframe line. The keyframe line for any video clip on the Video 2 or above tracks can display either effect () or opacity handles (). The keyframe line for an audio file can display effect, volume, or pan () keyframes. To display effect keyframes for either type of clip, click the effect keyframe button ().

Note: When the Video 1 track is collapsed, displaying both the A and B track on one line, Premiere displays the keyframe line for the Video 1 A track, or for the selected clip.
