I have a video of a seminar presentation that I would like to add the powerpoint slides to so they are more easily seen. Does anyone know how I could get this done? I would still like the audio over the top of it, but just don't need the video of the person talking. I have the imovie hd, is it possible to do it there? does anyone know any "idiots guides" to getting it done? I would also like to highlight some points on the powerpoint slide if possible, so what the presenter says is underlined or highlighted in some way. Any help would be really appreciated.
