After you’ve assembled a movie (arranging, deleting, and trimming clips), you can add polish to it by applying effects to clips. For example, an effect can alter the exposure or color of footage, manipulate sound, distort images, or add an artistic feel. All effects are preset to default settings so you can see the results of the effect as soon as you apply it. You can change these settings when you apply an effect to suit your needs.
You can also use effects to rotate and animate a clip, or adjust its size and position within the frame. Premiere Elements also includes several preset effects that you can use to quickly alter your footage. Most effects have adjustable properties. However, some effects, such as Black & White, do not have adjustable properties.
When you apply themes or create an instant movie project, Adobe Premiere Elements automatically applies effects to your clips.
