How to Add Music and Fade-in and Fade-out Effects in iMovie 11

How to Fade-In and Fade-Out Music

Turn on the advanced tools by going to Menu > Preferences > Show Advanced Tools. This will give you access to the Waveform Editor, which appears at the bottom of the Project Browser window as a button with a squiggly waveform image on it.

Click the Waveform Editor button to display the music and audio in your video clip.

In the Waveform Editor timeline, position the pointer over the audio clip. This will bring up the fade handles. 

Drag the fade handle to the points in the timeline where you want the music fade to start, and then drag the handle to the point you want the music fade to stop.

If you drag the handle to the beginning of the clip, you will get a fade-in, while dragging to the end will create a fade-out.

In iMovie, you can access music and sound effects by clicking on the music note in the center-right part of the screen. This will open up the iMovie music and sound effects library, where you can access your iTunes library, Garage Band songs, as well as music and sound effects from iMovie and other iLife applications.

You can sort music by song title, artist, and song length. You can also use the search bar to find particular songs.

When you've selected a song, drag it from the music library to the timeline. If you want the song as background music for the entire video, drop not on a clip but on the gray background of the project editor window.

How to Add Music to Part of a Project in iMovie 11

If you only want the song included for part of the video, drag it to the spot in the sequence where you want it to begin. The musical track will appear underneath the video clips.

Once it is placed in a project, you can still move the song by clicking and dragging it elsewhere in the timeline.​
