It works.

Why does iMovie need to fill the 60 gigs left on my internal drive in my trashcan powermac with temporary files when editing a 5 minute movie? I don’t know, but this program is easy to use, and can crop, trim, merge, and convert my videos reliably, without the headaches of imovie. Just take the time to tell it where to put the finshed file, and in what format.
