I have a video clip that is 1:08 in length. When I play it, the slideshow pauses for a long time on the photo preceeding it, then it only plays 30 seconds of the clip before moving on. I tried splitting the clip in two 30 second pieces, but then it started up the second clip right on top of the first one! I really need help with timing in this slideshow. Does anyone know what I have to do to tweak timing?
