I have an iMovie that is basically a slide show (a bunch of photos of graduating seniors). I threw it together at the last minute because the parents got pictures to me late. One of the things that I didn't do was drop cross-dissolve transitions between the photos. I've already got the music timed to different sequences of pictures. When I drop a cross dissolve between two pictures, it actually makes the whole sequence shorter and I can't figure out how to compensate. I assume a 1:01 transition takes 1 second and 1 frame from each of the two clips and overlaps them. This would shorten the overall sequence by 1:01 because the second clip is effectively being moved forward by 1:01 to overlap with the last 1:01 of the first clip. Does that sound right? I tried lengthening each photo clip from 5 seconds to 5:15 so that a 1:01 transition would only shorten the sequence by 1 frame. It still seems to come up short. Does anyone know of a foolproof way to compensate for the time changes that a transition will introduce?
