In the video, a man is seen walking on a tennis court while holding a flag. He is wearing a blue shirt and black pants. The man is holding a flag in his hand and appears to be signaling something. The court is surrounded by a fence, and there are trees visible in the background. The man seems to be focused on his task, and his movements are deliberate and precise. The flag he is holding is brightly colored, making it stand out against the blue of his shirt. The court itself is well-maintained, with clear lines marking the boundaries. The man's actions suggest that he is likely a referee or official of some sort, responsible for making decisions during a tennis match.
