This tip is directed at people who love the Ken Burns effect which essentially is the slow zoom into a photo. The effect at times induces flickers while moving (especially vertically) which is unacceptable if it is meant for broadcast. This usually tends to happen when the photo itself is not scanned but rather shot at -- something that happens in run-n-shoot documentaries all the time. Creative Mac has some really nice tips in how to eliminate those flickers. Even to those quite familiar with Final Cut can learn a thing or two from this article.
