After you activate the keyframing process, keyframing involves nothing more than repeating the same two steps: setting the current frame of the clip and then setting the effect’s property values for that frame. (Remember: Set values only for the “key” frames; let Premiere figure out the in-betweens.) The specific steps are outlined in the following tasks.
To prepare to animate an effect:
In the Timeline window, expand the track containing the clip with the effect you want to animate by clicking the triangle next to the track’s name (Figure 11.39).
