If you're only planning to buy one Final Cut Express (FCE) book, buy Tom Wolsky's "Final Cut Express Editing Worship." If your planning to buy TWO FCE books, buy TWO copies of Mr. Wolsky's book.
Okay, you probably don't need to buy two copies, but once you've read this book and worked your way through the tutorials, you will have mastered FCE and won't need of any other guides for working with this powerful program. If you ARE intent on buying a second book, buy something that deals with the art of film making instead.
I give this book 5 stars for two reasons: First, it covers everything about FCE and is packed full of hints and tricks that will greatly improve your productivity and the quality of your work. Second, Mr. Wolsky covers all of FCE's facets from beginning to end in a manner that's logical, easy to follow, and he writes in a casual prose that gives you the feeling that your best friend (who also happens to be a genius) is sitting next to you, gently guiding you through the entire process.
My only regret is that this book wasn't available BEFORE I worked on my first couple of projects. Take my advice, buy this book and work through it before you take on your first project. You'll be glad you did.
