In the video, a person is seen working on a car engine. The person is holding a small black object in their hand, which they then insert into a hole on the engine. The person then takes a wire and connects it to the object. The engine is silver and there are various other components visible in the background. The person's hand movements are precise and deliberate, indicating that they are experienced in working with car engines. The video does not contain any audio, so it is unclear what the person is saying or doing. However, the visual cues suggest that the person is performing some sort of maintenance or repair on the engine.
