Create a video soundtrack in GarageBand on Mac
Creating a new video soundtrack is similar to working with any other GarageBand project. You can use your own recordings, arrange them, add media files, and mix your music, dialogue and sound effects.
When working with a movie file, it’s often important to match (or synchronise) the soundtrack with what you see. To help match events in the soundtrack with those in the movie, you can switch the time format in the LCD to Time to align regions and other items with points on the ruler that may not fall on a bar or beat. You can also adjust the project tempo or add tempo changes using the Tempo track, so that key points in the video align with the bars and beats.
