Chapter 7 Using Special Effects 55

Motion Effects

You can make a clip play backward, and you can make whole clips or parts of clips play

in slow motion or fast motion. If you reverse the direction of a clip, you can also slow it

down or speed it up in reverse.

Making a Clip Play in Reverse

You can apply the reverse-motion effect only to a whole clip. If you want to make only

a few frames play backwards, separate those frames into their own clip by splitting the

clip at the start and end of the desired frames.

To reverse clip direction:

1 Select the clip you want to reverse. You can select a clip in the clip viewer, the timeline

viewer, or in the Clips pane.

2 Click Effects.

3 In the Effects pane, choose the Fast/Slow/Reverse effect.

4 Click the Reverse Direction checkbox.

5 Click Apply.

An icon appears on the clip in the clip viewer to indicate that the clip has been altered.

When you play the clip, it plays backward.

You can choose Edit > Undo to cancel the effect, or select the clip and press the Delete

key.

Speeding Up or Slowing Down Your Video

You add slow- and fast-motion effects using the clip speed slider that appears in the

Effects pane.
