Trimming audio clips

The Timeline audio tracks

The Movie Window’s Timeline view contains several audio tracks:

Original audio track: This contains the audio captured along with your video clips. It is sometimes called “synchronous” audio because it is recorded simultaneously with the video track.

Sound effect track: Sound effects and voice-overs are the typical content on this track. Sound effects are brought into your project from the Sound Effects section of the Album.

Background music track: Use this track to include mp3 or wav audio files and music (or other content). Audio files are imported via the Music section of the Album.

The Timeline audio tracks: original audio, sound effect and background music.

Switching audio tracks

Once a clip has been created, however, you can move it to a different audio track if it is convenient to do so: each track is actually able to accommodate any type of audio clip.

The only audio track with special status is original audio for the main video track. By default, audio clips on this track are edited in parallel with the contents of the video track at the same time index.
