HOW TO Detach audio from a video clip

1 Detach audio

Select the clip in the timeline from which you want to detach audio by clicking it. Click the Modify menu and choose Detach Audio, or press Cmd+Opt+B. You will then see a separate audio track appear.

2 Adjust audio

Select the audio clip — the green rectangle with the waveform in it — and click the loudspeaker icon above the viewer. Choose Auto to automatically set the volume, or use the slider to adjust it manually.

3 Edit the audio clip

By default, the audio starts mid– transition. You can change that by clicking it and dragging it to where you want it on the timeline. And you can trim or split the audio clip in the same way as we did for video in step 8 on p71.
