When making my (Pan and Scan) edit of DUNE, I had to do a great amount of sound editing and mixing. I spent as much time working in Cool Edit (Audio editing program) as I did video editing in Adobe Premiere. One trick I used was to make small background sounds and drop them in under edits. For Leto's office scene, we used a cue from the soundtrack CD mixed with some new sound effects that we made using a microphone. My edit is riddled with small audio changes. Some video was extended to fit the soundtrack playing, or soundtrack was changed to fit the video. The re-edit of "THE BOX" scene was very involved, and took a few days to make it passable. Still, I believe my version of this scene flows and makes much more sense than any other version. The arrival at DUNE, where the local people take a look at Leto and family was also a tricky sound edit.
