When the upgrade to Apple's Final Cut 4.0 arrived, I was pretty impressed with some of the latest feature additions... then I stumbled upon the included Soundtrack application and was completely blown away! This amazing tool allows musically challenged videographers (like myself) to create complex, lush, brilliant musical scores with very little effort. It's just a matter of selecting various instrument loops from the included (and impressive) library and putting it all together. Start with a funky drum beat, add a synthesizer or two and some strings, and you're done! Even more impressive is that Soundtrack handles all the timing, so you can lengthen or compress the tracks to match cues in your video effortlessly. I was able to create a complete musical score for a 5 minute video that contains 27 tracks in just under an hour, and it sounds amazing. Yet another coupe for Apple that makes me so very glad I own a Mac. If you create video content, and don't have the luxury of hiring a composer to arrange a score for your project, then you need this incredible app!
