Hmm...I've never used it before, but I think I know what your problem is. When you create a video is it a 4:3 video or a 16:9 video? If it's a 4:3 video, anything that is widescreen will be crunched down so that it has black bars at the top and bottom. Because youtube players are widescreen that will cause black bars on the side of your videos to form as well (which is why there are black bars on the side of your alltp footage). Your best bet is to create a 16:9 video so that your outro isn't crunched like that! Best of luck!
