The video shows the shadow of a person cast on the bottom of a swimming pool. The person is standing, and their shadow is elongated and distorted by the ripples on the water's surface. The sunlight refracts through the water, creating shimmering patterns on the pool tiles. The water is a clear blue, and the tiles are a light blue with darker grout lines. The shadow suggests a person of average build with arms and legs. There is no other visible activity or objects in the frame.
