iMovie, like all of Apple's iLife (and iWork) apps, received a substantial makeover to coincide with iOS 7 and OS X Mavericks. Whether you've been using iMovie for a while, or are just coming to it now, Serenity Caldwell has put together a fantastic list of tips to help you ramp up on the new version. Macworld:
Apple’s new version of iMovie is sleek and sophisticated both on the Mac and on iOS devices. It retains a lot of advanced features from prior versions, but keeps its interface clutter- and confusion-free for newer users. And it’s added a new avenue for easily sharing movies to your computer and Apple TV. I could go on like this for awhile, but instead of writing a whole review here, I’m going to cut to the juicy parts and focus on twenty new and improved features in iMovie for the Mac and on iOS.
They're all great. Check them out and then let me know - how are you liking the new all new iMovie?
