This is a vertical video clip of a man-made wave pool in Rotterdam, Netherlands. The pool's water is a vibrant, murky green. In the foreground, a person in a red shirt paddles a surfboard. Further back, several other individuals in red shirts are also on surfboards or swimming in the choppy water. In the mid-ground, a distinct wave is breaking, and a person in a red shirt is actively surfing it on a white surfboard. Behind the wave, a group of people in blue and yellow shirts are gathered on a concrete platform, possibly instructors or onlookers. The background reveals a multi-story building with many windows, suggesting an urban environment. Overhanging trees frame the top of the scene. The sun is bright, indicating a clear day. The overall mood appears to be recreational, with people enjoying water sports. Visible text includes "RIVERSURF" on a black and white sign on a white structure to the left of the wave.
