The video shows a large wave in the ocean, with a surfer riding it. The surfer is seen paddling on his surfboard and then standing up to ride the wave. The wave is quite large and powerful, with white foam forming at the top. The surfer manages to stay upright and ride the wave for a while before eventually falling off the board and disappearing under the water. The ocean is a deep blue color, and the sky is clear with no clouds visible.
