    Chapter 7. Advanced Effects > Exploring on your own

    Exploring on your own

    1.
    Experiment with the various effects presets located in the Effects and Transitions panels, specifically, the Horizontal and Vertical image pans.

    2.
    Using the effects_soundtrack.wav clip in your Audio 2 track, add 2 new keyframes at the beginning of the clip. Change the volume levels so that the beginning of the clip is louder and then decreases when the man starts talking.

    3.
    Create two new Gaussian Blur keyframes on the Effects2.avi clip to create an effect which blurs out.

    Review questions

    1: What is a keyframe and what does it contain?
    2: How would you change the volume of a clip over time using keyframes?
    3: How do you modify keyframes once they have been added to a clip?

    Review answers

    A1: A keyframe contains the values for all the controls in the effect and applies those values to the clip at the specific time.
    A2: Each Premiere Elements clip in the Timeline has an orange connector line which controls the keyframes of the clip. To add keyframes, you Ctrl+click on the line. You must have at least two keyframes with different values to automatically change the level of the volume of an audio clip.
    A3: Once keyframes have been added to a clip, they can be adjusted by clicking and dragging them along the connector line. If there are two keyframes, moving one keyframe farther away from the other extends the duration of the effect; moving a keyframe closer to another keyframe shortens the effect.
