I am a very new user to Movie Studio and am having trouble fitting the videos we make in Platinum to fit our Virtual outdoor 5x7 LED Screen. The videos look good in the preview window in Platinum itself but when displayed on the LED there are black lines at the top and bottom. It looks like we should be able to make our display bigger to fill the entire screen but I can't figure out how in the world to fix this problem??? I have spent hours trying to learn what step / setting I need to take or change. If anyone can teach me what I seem to be missing I will be forever grateful!!!
