Make Audio and Video Adjustments to iMovie Video Clips in iLife '11

3 of 12 in Series: The Essentials of Editing Video with iMovie in iLife '11

In iMovie for iLife, you can adjust the audio in video clips, especially ones that are louder or softer than others, so that they sound better when included in a project. You can also adjust the video image itself, to increase or decrease exposure, brightness, contrast, and saturation, and adjust the colors of the entire image according to a white point in the image.

To make adjustments, follow these steps:

  1. Select a clip in the Event Browser.

  2. Click the Gear icon that appears when you move the pointer over the lower left corner of the selected filmstrip, as shown in this figure.

    Choose Audio Adjustments from the Clip Adjustments menu.
    Choose Audio Adjustments from the Clip Adjustments menu.
  3. To adjust audio settings, choose Audio Adjustments from the Clip Adjustments pop-up menu, and make your adjustments.

    The Audio pane offers a slew of controls to help make clips sound more in harmony with each other. (Forgive the pun.)

    If you prefer, you can double-click the selected clip in the Event Browser to show the Inspector window, and then click the Audio pane.

    You can make adjustments to the clip’s audio, including overall volume.

    Or, choose Video Adjustments from the Clip Adjustments pop-up menu. The Video pane appears.

  5. When you’re satisfied with your changes, click Done in the lower right corner of the Inspector window.

You can also edit the audio portion of the video clip directly in the Event Browser. Click the audio waveform button in the lower right corner of the Event Browser window to show the audio waveform underneath each video clip. You can then drag the volume line in the waveform up (to raise the volume) or down (to lower the volume), and the waveform representing the audio moves up or down with it.

Click the audio waveform button and drag the volume line to adjust the audio part of a clip.

You can even edit only a portion of the audio — click the audio waveform once for a clip and a yellow rectangle appears, defining the area to make your adjustment. Drag the edges of the rectangle to cover the area of the waveform to adjust, and then drag the volume line to adjust the volume. Two yellow fade points appear at either end of the volume line, showing where the volume adjustment begins and ends — the volume is set to automatically fade down or ramp up to accommodate the adjustment. You can adjust the fade points to shorten or lengthen each fade.
