The video shows a person swimming in a pool. The swimmer is wearing a black swim cap and goggles, and is performing the freestyle stroke. The water is a clear blue color, and the swimmer's movements create ripples and splashes on the surface. The swimmer's arms are moving in a coordinated manner, alternating between the front and back of the body, while the legs are kicking in a frog-like motion. The swimmer's head is visible above the water, and they appear to be breathing to the side.
