sora 2 Prompt: Ultra-realistic cinematic 5-second video, vertical 9:16. A cute 8-month-old baby sits safely on a soft play mat in a bright cozy living room, facing a tiny adorable fluffy kitten. The baby looks seriously at the kitten and clearly says in a cute baby voice: “No miau miau!” The kitten immediately looks at the baby and answers with a clear, adorable: “Miaou!” The baby starts laughing, surprised by the kitten's response. The kitten's mouth movement is naturally synchronized with the meow. Photorealistic, natural facial expressions, realistic baby and kitten movements, warm daylight, cinematic close-up, authentic funny viral home-video style. Audio: clear baby voice saying exactly “No, miau miau!”, followed immediately by one distinct realistic kitten “Miaou!” and the baby's happy giggle. Natural room ambience. The dialogue and meow must be loud, clear and perfectly synchronized with the characters' actions. No music, no voiceover, no subtitles, no text.
