Hi, Bram
A couple of suggestions for you:
1) FCP has a function called Media Manager which is designed to track down all the media used in your project and consolidate in a single location of your choosing (such as an external hard drive). Not all of us use it, trust it or agree with the philosophy behind it, but it’s there. You might want to read about it in the manual and decide if it will work for you.
2) Shane Ross has a DVD in the Cow Master’s series entitled “Getting Organized in Final Cut Pro” which you might consider purchasing. It’s full of good advice.
3) You might consider posting your questions on the Cow’s “Final Cut Pro Basics” forum until you get a little more familiar with the program and how it works.
4) At the top of each forum page is a search box. If you try it, you may find that many of your questions have been asked and answered before.
Good luck and happy editing!
