The video shows a person using a machine to sand down a piece of wood. The person is holding the wood in their hand and moving it back and forth over the machine to smooth out the surface. The machine appears to be a belt sander, which is commonly used in woodworking to shape and smooth out wood pieces. The person's hand is steady, and they seem to be experienced in using the machine. The wood piece is circular and appears to be a part of a larger project. The background is blurred, but it seems to be a workshop or garage setting.
