To adjust a portion of the soundtrack you selected to a specific part of your project, you can follow these steps:
- Select and add one soundtrack from the Audio section, by tapping on the Music icon (a music note)
- The selected song will appear as a red bar in the Audio section, right under the project preview
- Tap on the white side handles of the red bar, hold your finger, and move it to the left or to the right: this way you can set the length of the soundtrack and its starting point
- Then, by pressing your finger on the red bar (not on the side handles) and moving it to the left or to the right, you can make sure that the soundtrack matches the clips you thought it for.
If you are interested in adding more than one song, it will be enough to repeat the process with all the soundtracks involved.
