In the video, a person is seen holding a cylindrical object wrapped in red and white wires. The person is using a soldering iron to connect the wires to the object. The object appears to be a coil of some sort, possibly a transformer or an inductor. The person is wearing a red sweater and is working on a wooden table. In the background, there is a piece of paper with a diagram of the coil and other electrical components. The person seems to be testing the connection by touching the wires to the coil. The soldering iron is emitting a small amount of smoke as the person works. The video ends with the person placing the soldering iron on the table and looking at the camera.
