In the video, a person is seen painting a yellow object with a brush. The object appears to be a square-shaped container or box. The person is using a brush to apply a substance, possibly paint or a coating, onto the surface of the object. The brush strokes are smooth and even, covering the entire surface of the object. The person's hand is steady, and they seem to be experienced in handling the brush. The background is not visible, and the focus is solely on the painting process.
