Origami is very nice. However, detailed control is, in my case, very hard to live without. I am setting up a 10-minute slide show. I want to use several pieces of audio cued to different points in the show. I want to have some sections, and origama shuffles my pictures across the section boundaries. Even text slides don't clue it in that this might be a good place not to shuffle across. Some of my consumers find the plain 'Ken Burns' transition in imovie positively sea-sickness-inducing.
I can predict that the answer will be that, inside iphoto, I'm in the traditional 'Steve Jobs is the reincarnation of Henry Ford' situation, and I won't be finding any way to exercise detailed control. So, can anyone give me a running start on how to introduce other transition effects to imovie?
