The video shows a close-up of a person's hand as they work on a red engine. The person is using a tool to remove a bolt from the engine. The camera angle is from above, and the person's hand is visible in the frame. The engine appears to be in a vehicle, and the person is wearing a red shirt. The tool used is not clearly visible, but it seems to be a wrench or a similar type of tool. The person's hand is steady, and they seem to be experienced in working on engines. The video does not show the entire engine or the surrounding area, so it is unclear what type of vehicle it is or what the purpose of the repair is.
