I am creating a slide show for a banquet and want to include some video. I planned to import photos into iMovie and create a video of both the video piece and the photos. I need to project it so that over 100 people can view it. I want the quality to be as good as possible since it will be projected onto a screen. Will the quality of the photos be degraded by bringing them into a movie? Am I better off showing the photos on an iPhoto slideshow since I will be projecting it? Thank you....
