Video prompt: The tree is adorned with twinkling lights and a variety of colorful ornaments. With a look of concentration, the toddler carefully places a glittering gold star on the very top of the tree, reaching up with both hands. Once the star is secure, the toddler giggles with delight and claps their hands. Nearby, a crackling fireplace casts a warm glow across the room, and the scent of pine fills the air. The toddler then eagerly picks up more ornaments from a nearby box, selecting a shiny red bauble and a silver bell, and hangs them on the lower branches, occasionally glancing back at a smiling parent who watches proudly from the couch.
Defect: Blurring (abnormal blur, e.g. one bird of a group blurs)
Explanation: There is a subtle, but abnormal blurring that occurs on the baby's chin for a moment. This makes the video look very unnatural
