In the video, a person is seen holding a black wire with a red connector at one end and a yellow connector at the other end. The person then proceeds to plug the red connector into a black box with several other wires connected to it. The box appears to be a power source or a hub of some sort. The person then takes the yellow connector and plugs it into the same black box. The video seems to be demonstrating how to connect the wires to the box. The background is not visible, and the focus is solely on the person's hands and the wires.
