Video editing application for Mac I'm interested in starting to edit videos and I'm looking for a good video editing application. It shouldn't be too complicated but one should be able to do advanced stuff with it too. I currently got iMovie but it's too simple for me. 

Any tips?
I can recommend Final Cut Express and if you want it real pro - Final Cut Pro. Note that a major new Final Cut version is nearly out - probably with the MacOS X Lion. Also note that some price drop is expected for both products, probably you should wait a month.
