In the video, a person is seen working on a wooden block that is clamped down to a workbench. The person is using blue tape to mark lines on the block. They carefully place the tape along the edges and then use a ruler to ensure that the lines are straight. The person's hands are steady as they work, and they take their time to ensure that the lines are precise. The wooden block appears to be light in color, and the blue tape stands out against it. The workbench is made of wood and has several holes in it, possibly for clamping purposes. The person's movements are deliberate and precise, indicating that they are experienced in this type of work.
