To launch Stitch from the finder, select a compatible video and audio file. With both files selected, right-click on one of the files and select 'Open with' -> 'Stitch'. Stitch will replace the audio in the video with the selected audio file, and create a new file on the same location as the original video file.

You can open Stitch by double-clicking it in the Apps folder. To add a video and audio file, do one of the following:

• Select 'Open...' from the File menu, and select a video and audio file
• Drag and drop a video and audio file from the finder on the Stitch window
• Click the 'Add video...' and 'Add audio...' button

When a compatible video and audio file is loaded, you can press the 'Stitch' button, to replace the video audio with the selected audio file. A new video file will be created on the same location as the original video file, and Stitch will show it in the Finder.

Install stitch by unpacking the downloaded .zip file. Then double-click the installer and run it. Stitch will be installed in your Apps folder.

To uninstall Stitch, move the following files to the trash:

• 'Stitch' in the Apps folder
• the file ~/Library/Preferences/com.speakerfood.Stitch (if present)

Not all video and audio formats are compatible. Stitch will show a warning when this is the case. Try converting the video or audio file first, to make them compatible with each other. The .mov video format is compatible with all supported audio formats.
