The video shows a person using a sewing machine to stitch a piece of leather. The person is using their left hand to hold the leather in place while the machine stitches it. The leather appears to be a piece of a bag or a wallet, and the stitching is being done in a straight line. The person's hand is steady, and they seem to be experienced in using the sewing machine. The background is not visible, so it is unclear where the person is sewing.
