Special Effects: Using Effect Controls 140 Changing effects over time Some Premiere effects change dynamically; some change over time. Effects that change dynami- cally use keyframes to tell them when to make changes. Effects that don't have settings associated with them, such as the Black & White effect, don't need or use keyframes, so they can't be changed in this way. For effects that don't use keyframes, you can often create change over time using transitions, al- though this technique is not as flexible nor as precise as using keyframes.
