I have read several places that I should be able to use Ken Burns on video clips in iMovie '09. I purchased my Macbook Pro with iLife 09 about one month ago, but I don't seem to have this effect. When I click on a clip, I only have the option to Fit or Crop or rotate. In every tutorial I've seen, the Ken Burns button is directly next to the crop button. What am I missing? Thank you!!
