The video depicts an indoor swimming pool

The video depicts an indoor swimming pool. The pool is rectangular with swimming lanes marked by ropes. The pool area is enclosed by large windows and a blue, translucent roof supported by a metal frame. The lighting is dim, with sunlight filtering through the roof. The pool deck is tiled in white and gray. A yellow hose runs along the edge of the pool. A white object, possibly a chair or part of a piece of equipment, is visible in the foreground. There is at least one person swimming laps in the pool. A yellow warning sign is visible near the edge of the pool. The water has gentle ripples.
