I think it’s mainly because of the “Noise Reducer” effect that iMovie has that has helped me out immensely over and over again. I’ve tried “Hum Remover” in Final Cut Pro but it’s not the same.. Noise Reducer in iMovie really tones down the sounds and makes the important sounds pop without sounding too excessive. I agree that FCP sound editing would probably be the better choice but my fondness for the “Noise Reducer” effect in iMovie is pretty rock solid.. Thinking I might just bring every single sound and audio effect through iMovie and apply the “Noise Reducer” to each clip I feel that needs it, then export those sounds as individual .WAVs that I will then bring into FCP (or SoundtrackPro).. Would that work a little bit better? Thanks for your help. 🙂
