Abstract: To provide an information processing system that can improve the quality of a running commentary that uses a recorded video.

Abstract: A video generation system is disclosed including a processing device, a game device that outputs, to the processing device, game video and game data that comprises a position coordinate of an object in a game and information in accordance with progress of the game, a generation device, and a display. The processing device receives the game data and processes the game data into a predetermined format. The generation device acquires the processed game data from the processing device, and generates content to be composited with the game video using the processed game data. The display displays the content composited with the game video at a position synchronized position coordinate.
