In the video, a person is seen using a tool to measure a piece of wood. The tool appears to be a combination square, which is a tool used for measuring and marking straight lines on a surface. The person is holding the tool against the wood and using a pencil to mark a line on the wood. The wood is a light brown color and appears to be a piece of lumber or a similar type of wood. The tool is metallic and has a ruler attached to it, which the person is using to measure the length of the wood. The person's hands are visible in the video, and they are wearing a blue shirt. The background is not clearly visible, but it appears to be an outdoor setting.
