A computer-implemented method involves accessing a library of video segments, receiving a user instruction to assemble a movie related to an organizing element that includes a video segment from the library of video segments, relating the organizing element to a video segment in the library of video segments, determining, based on relating the organizing element to the video segment in the library of video segments, whether the video segment should be added to a list of selected segments used to assemble the movie, selectively adding the video segment to the list of selected segments in response to determining that the video segment should be added, and assembling the movie using the list of selected segments.
