My render is corrupted

Make sure that when you are rendering your movie, that you do not obscure the picture that is being rendered.

You may need to set Moviestorm to use fullscreen mode - if the Moviestorm window is not at least as large as the video resolution you are rendering to, then the edges or top and bottom may be not rendered correctly.

You may need to disable your screensaver while rendering, so that it doesnt interupt the render.
