Apple’s iMovie and Final Cut give Mac users intuitive tools for editing their home movies from dry, amateurish “Wave to the camera, kids” productions into something that’s actually worth watching. But if you start with cruddy footage, there’s only so much you can do in post-production to improve it. Two of the biggest problems that can’t really be fixed later on are poor sound quality and a jittery camera. So when you’re ready to take your backyard epics to the next level, we offer the following improvements to your movie-making setup. They won’t break the bank, but they’ll definitely improve your work. Next stop, Sundance?
