The video shows a computer-generated animation of a large brown dinosaur with sharp teeth and claws. The dinosaur is standing in a lush green forest with trees and bushes. There are two small human characters, one wearing a beige outfit and the other wearing a pink outfit, standing near the dinosaur. The dinosaur opens its mouth and roars, and the two human characters run away in fear. The video is set in a bright, sunny environment, and the animation is smooth and realistic.
