Modelo de prompt para vídeo com IA: Prompt de AI Laughing Face efeito vídeo

Transform the person in the uploaded image into a natural, warm laughing expression while preserving their identity, facial structure, age, hairstyle, outfit, pose, background, lighting, camera angle, and overall image style. Create a believable laughing effect: gently lift the cheeks, slightly narrow the eyes, add a relaxed open-mouth smile or visible teeth only if anatomically natural, and adjust the lips and jaw subtly to match a real laugh. The expression should feel candid, joyful, and realistic, not exaggerated or cartoonish. If generating video, add subtle natural motion: a small head movement, slight shoulder or body movement, soft cheek motion, natural eye squint, and gentle mouth movement as if the person is laughing briefly. Keep the motion smooth, stable, and consistent with the original photo. Do not change the person's identity, face shape, skin tone, hairstyle, clothing, body proportions, background, or composition. Avoid distorted teeth, warped lips, asymmetrical facial features, unnatural mouth opening, excessive wrinkles, fake-looking expressions, or dramatic changes to the scene. Final result should look like the same person naturally laughing in the original photo, with realistic facial anatomy, clean details, stable features, and a polished social-media-ready appearance.
