Changing a Clip s Volume


Changing a Clip's Volume

When you import footage, the video and audio are combined in the Timeline Viewer's video track (Figure 10.1). So, as you're editing video clips, you're also editing the audiosplitting, trimming, and cropping it with the visuals. You can control how loud an individual clip plays, or change the volume level within the clip.

Figure 10.1. Although the top track is usually referred to as the video track, it also contains the clip's audio.


To set a clip's volume evenly:

1.

In the Timeline Viewer, select one or more clips you want to edit.

2.

Use the volume control slider, or enter a percent value in the field, to set the clip's volume (Figure 10.2).

Figure 10.2. With a clip selected, drag the volume control slider to adjust the clip's volume uniformly. The volume level bars appear while you drag.


To change volume within a clip:

1.

In the Timeline Viewer, select the clip you want to edit.

2.

Choose Show Clip Volume Levels from the View menu (Figure 10.3), or press Command-Shift-L; a purple volume level bar appears within the clip.

Figure 10.3. When you're editing the audio for multiple clips, you may want to keep this option on.


3.

In the Timeline Viewer, click on the volume level bar to set a marker where you want the volume change to occur (Figure 10.4). iMovie creates the marker (a yellow circle) and a beginning point for the marker (a small square).

Figure 10.4. iMovie can edit volume levels within a clip. The audio between the beginning point and the volume marker is automatically incremented smoothly to a louder or softer level.


4.

Drag the marker up or down to increase or decrease the volume. All audio following the marker in that clip is affected.

5.

Drag the marker's beginning point to the right or left to determine how quickly the volume change occurs.

To remove a volume marker:

1.

Click a marker to select it.

2.

Press the Delete key.
