The video appears to be taken from a boat or yacht in a harbor, likely in Monaco. The view is towards a Formula 1 racetrack that runs alongside the water. The distinctive Monaco flag, white and red, is visible in the foreground, obscuring the view at times. You can hear the sound of a Formula 1 car speeding by on the track. The background consists of tall buildings lining the harbor, indicating a densely populated urban area.
