Well, for one thing, gifs are NOT video files, they are image files with many frames to be animated, but they don't work well with the amount of frames you're asking for and I'm assuming the length, so that could be your problem. It would be best to use an external recorder and press tab in US2 before you start recording recording (The turn off UI button is still tab...right? I'm not sure) Then you can ue whatever format you want...that is an actual video file.
