title: Change Soundtrack properties in QT 7 pro - Batch with applescript
body: <p>I need to change the soundtrack properties (movie properties tool in QT 7 pro) for a whole bunch of video files. The process would be:
  in movie properties click on sound track
  and then change the assignment of each audio channel from Mono to "center"
  save the file(s)</p>
  
  <p>I am completely unexperienced with Applescript but would it be possible to have a script that would automate that process so I can apply it to all the files without having to do it manually on each QT file?</p>
