Yachtsman1, Any editing done to a video file (whether to the image or the sound) has to work to whole frames. Therefore, there is always going to be the possibility that the final result will not be EXACTLY equal to the length that you specified. One solution is to always have a little bit more video length than the slide duration that you specify, so that any slight mis-match will be lost in the outgoing transition. That doesn't work if you are using "Quick" transitions, of course. regards, Peter
