In the video, a person is holding a small black object in their hand. The object appears to be a lens or a filter of some sort. The person then proceeds to unscrew the top of the object, revealing a red light inside. The light is turned on, and the person holds the object up to the camera, allowing the viewer to see the red light clearly. The object is then turned off, and the person screws the top back on. The video ends with the person holding the object up to the camera once more.
