I’m beginning to work more with movie files, especially 15-30 second snippets captured from a still camera. If you’ve collected a large number of these, it can be a tedious task to concatenate these into one QuickTime file for editing. I found this AppleScript code at MacOSXHints, and created an applet, which does just that. Select a number of QuickTime snippets and drag and drop over this applet to have them concatenated into one larger QuickTime file.
