This is an easy one. And, yes, people still use QuickTime 7. In fact, pretty much anybody who has had anything to do with editing videos on the Mac for the last five or so years has been using QuickTime Pro for this purpose and they will continue to do so until QuickTime X actually gets updated like Apple “promised.” Rather than sit around and wait for it, though, we’ll just keep using QTP instead. Saves us a lot of time, grief, hassle, etc. Besides, other than recording your screen and a little bit of trimming capability, there isn’t much appeal for professional or even novice video editors with QTX. Thanks, but keep trying.
Keep trying, Mrs. Florick. You’ll hit on it. -The Good Wife
