An information processing device generating video data representing a video of a moving object in response to an instruction by a user includes a decision unit, a determination unit, a generation unit, and a warning unit. The decision unit decides a movement path of the object, based on an instruction by the user. The determination unit determines whether an object video showing the object moving along the movement path decided by the decision unit is equivalent to a video for repeated playback or not, based on the movement path. The generation unit generates video data based on the object video when the object video is determined by the determination unit as equivalent to the video for repeated playback. The warning unit warns the user when the object video is determined by the determination unit as not equivalent to the video for repeated playback.
