How to quickly replace an audio track in a QuickTime movie

Sometimes you need to swap out an audio track if there's a problem or you need to provide multiple languages or different soundtracks.

Instead of compressing the video again, QT Edit makes it really easy to do this in just a few steps.

1. Open up the movie file in QT Edit.

2. Select the existing audio track and press the - button to delete it.

3. Click the + button and select Audio. Browse for the new audio, which can be an AIFF, WAV or another movie file.

Important: QT Edit inserts the track at the current playhead position so make sure the playhead is at the beginning. If you make a mistake, manually set the start point of the new track to 00:00:00:00.

4. Double-check sync in the preview window and then hit Save.

5. You will be asked if you want to flatten the movie. This makes the movie self-contained. In most cases you will want to flatten, but if you want to create a reference movie select Don't Flatten.

QT Edit is just one of many useful utilities in the Pro Media Tools suite. To find out more, check out the feature list, watch the overview video, read the user manual or download the 15-day trial.
