I need to somehow highlight a portion of a video. For example, think of a video of someone changing a tire on a car. I need to be able to draw a circle around the tire, or point an arrow to the tire, or something like that. I have iMovie 08, 09 and just got Final Cut Express. (My how-to book is still on its way from Amazon.) Thanks a bunch. I've been using advice from you Mac gurus for years.
