In the video, a person is seen holding a circuit board in their hand. The board is green in color and has several components attached to it, including a yellow transformer. The person is using a tool to adjust the transformer, moving it back and forth. The board is held steady in the person's hand, and the tool is used with precision to make adjustments to the transformer. The person's fingers are visible, and they appear to be wearing a white shirt. The background is blurred, but it seems to be a workshop or lab setting.
