Hëlt `video_url` an e `prompt` a generéiert eng Fortsetzung vun `num_frames` Frames (9 bis 481). Eng optional `end_image_url` bestëmmt, wou d'Verlängerung ophält. `match_input_fps` behält de Frame-Taux vun der Quell, `generate_audio` füügt Toun dobäi, an `video_size` ass standardméisseg auto. Den Output kann mp4, webm, mov oder GIF sinn.
