The Special menu lets you preview video files so that you can quickly browse and find movies on your computer. You can play QuickTime, MPEG 4, AVI, DV movies, and any other video file that can be previewed with Quick Look.
To preview a video file, simply select it in the Special menu. If the Special menu does not play it, you may have disabled previews. To re-enable them, select the “Show previews in the Special menu” checkbox in the Previews pane of Application Wizard Settings (macOS 13 or later) or Application Wizard Preferences (macOS 12 or 11) and make sure that the “Play movies” checkbox is also selected.
