In the video, a person is seen holding a small rock in their hand. The rock is being painted with a red color using a paintbrush. The person's hand is steady as they carefully apply the paint to the rock, ensuring that the color is evenly distributed. The rock appears to be smooth and has a rounded shape. The background is blurred, but it seems to be a plain surface. The person's nails are painted with a dark color, possibly black or deep blue. The paintbrush used is small with a black handle and green bristles. The red paint is bright and vibrant, and the person seems to be taking care to avoid any drips or smudges.
