In the video, a person is using a metal tool to measure the depth of a large metal object. The tool has a yellow level on it, which the person is using to ensure that the object is level. The person is holding the tool with their left hand and using their right hand to steady the object. The metal object appears to be a large circular piece, possibly a part of a machine or a vehicle. The person is carefully measuring the depth of the object, possibly to ensure that it is within specifications. The background is not clearly visible, but it appears to be an industrial setting.
