Okay, if you buy Final Cut Express you're not buying the best video editing package available for the Mac: that, as the reviews say, is Final Cut Studio. But, then again, you're spending around £120 compared to the best part of £800 for the full show which, in anyone's books, is a massive difference in price. So, for 15% of the cost of its top-end brother what do you get and is it worth it?
Well... if all you want is a simple and, in it's latest configuration, deceptively powerful way of editing your videos then the latest version of "iMovie" will probably fit the bill. But, if you're into linear, time-line based editing then you'll probably find it difficult & frustrating to adapt to iMovie's "left-field" approach to it all. Professionals use time-line based editing - where you view and precisely control multiple video & audio tracks - for a very good reason: it's better. And, with Final Cut Express, what you're actually getting is an only marginally cut-down version of a highly complex and extremely powerful professional, time-line based editing package. Which means that it takes a considerable amount of time to learn how it works and it takes an equally considerable amount of time to make it work for you.
So, if you're not prepared to spend time fathoming all this out then the decision is simple: choose iMovie. Or, at the other end of the spectrum, if you're a professional, then ignore Final Cut Express and invest in Final Cut Studio's full, and necessary, range of professional tools. But... if you're a "top end" amateur who's prepared to go through the extensive learning curve that's involved here then rejoice, for Final Cut Express will deliver to you just about all of the features from its celebrated brother that you need (plus many, many more that you'll probably never use) at a price that's not only affordable but which must represent one of the best software deals out there.
