This is very strange. I render a movie as a MP4 and I get these strange lines that seem to be scrolling from top to bottom almost like a transition but begins about half way into the movie until the end. I'm not sure if I may have caused it but cannot seem to find a solution. I even deleted the movie and remade it and its still there. When I am editing in the Video Preview it does not appear. Only during/after the rendering.
I have VEGAS Movie Studio 15
