The video shows a person using a level to ensure that a picture frame is hung straight on a wall. The individual is carefully adjusting the frame while holding the level against it, making sure it is perfectly aligned. The setting appears to be indoors, with a window and some greenery visible in the background. The person is wearing glasses and a brown sweater, and there is another framed picture already hanging on the wall nearby.
A man stands in a room with a window showing greenery outside and a bed with a wooden headboard and metal rail. He uses a level tool to ensure a bracket is straight on the wall. He then removes his glasses and uses the glasses to mark a point on the bracket. After marking, he adjusts the level tool slightly to confirm its position. Finally, he uses the glasses to make a more precise mark on the bracket.
