A scrolling encoder encodes scrolling elements that are to be scrolled around all or a subset of the frames of a video stream or file with their movement in time and space controlled by a path to produce a video stream or file, without searching previous or subsequent frames of the video stream or file for reference blocks. The scrolling element can be an image, video, text or any combination thereof. The scrolling element is encoded using information about the contents of the scrolling element and information about a path the scrolling element is to take across a screen. The information about the contents of the scrolling element is obtained when the scrolling element is first introduced into a frame. The information about the path of the scrolling element is provided by an external component or is otherwise deduced. Optionally, the path information includes information about how the scrolling element is to change appearance. This information may be used to automatically generate error terms.
