In the video, a person is seen drawing on a blackboard using a piece of chalk. The person starts by drawing a single line, then continues to add more lines, creating a rough sketch of a tree. The person's hand is visible as they draw, and the chalk leaves a white mark on the blackboard. The person's movements are deliberate and precise, indicating that they are experienced in drawing. The blackboard is clean and unmarked except for the tree sketch. The lighting in the room is bright, and the focus is solely on the person's hand and the blackboard.
