The video shows a close-up of a person's hand wearing a blue glove, holding a paintbrush and applying a dark brown stain to a wooden surface. The person is using a back-and-forth motion to evenly distribute the stain across the wood. The wooden surface appears to be a wall or a fence, and the stain is being applied to a specific area, possibly to cover up a crack or imperfection. The brush is made of wood with a metal ferrule and a black handle. The stain is being applied in a controlled manner, suggesting that the person is experienced in this task.
