SCENE: Realistic TikTok Shop UGC selfie video, vertical 9:16. Preserve the influencer’s exact identity, face, hairstyle, body proportions, skin texture, clothing, colors, fabric, seams, logos, accessories, room, lighting, and original composition from the reference image. Do not redesign or replace any element. ACTION SEQUENCE: Natural approach: The influencer gently moves closer to the camera with a smooth, natural step, maintaining a friendly and confident expression. One arm remains extended in the same selfie-recording position, as if holding a phone outside the frame. The smartphone must never be visible. Product call to action: While remaining close to the camera, she raises her free hand and points downward with her index finger, making a clear, natural gesture toward the lower part of the screen, as if indicating the product purchase link. She repeats the downward-pointing gesture once, with a slight, friendly smile and a confident expression. Final pose: She briefly holds the pointing gesture, then relaxes her hand naturally while maintaining eye contact with the camera. Keep the clothing clearly visible and consistent throughout the movement. MOVEMENT STYLE: Natural human motion, smooth approach, realistic arm and finger movements, relaxed shoulders, friendly expression, and authentic influencer-style product promotion. The gesture should be easy to understand without appearing exaggerated or robotic. CAMERA: Selfie-style perspective with subtle natural handheld movement. The phone remains outside the frame at all times. Maintain the original perspective, background, lighting, and room geometry. No cuts, artificial zoom, or dramatic camera movement. VISUAL QUALITY: Photorealistic smartphone footage, natural indoor lighting, realistic skin texture, accurate shadows, smooth movement, and high temporal consistency. IDENTITY CONSISTENCY: Preserve all original facial features, hairstyle, body proportions, clothing details, accessories, and environmental elements throughout the video. AUDIO: Completely silent. No speech, narration, dialogue, lip movement, music, sound effects, or ambient audio. NEGATIVE PROMPT: Visible smartphone, phone appearing in frame, unnatural approach, exaggerated gestures, incorrect pointing direction, pointing upward, pointing sideways, multiple fingers pointing, deformed hands, extra fingers, missing fingers, fused fingers, duplicated limbs, robotic movements, facial changes, identity drift, hairstyle changes, clothing changes, altered logos, body deformation, unstable background, flickering light, excessive camera shake, sudden cuts, artificial zoom, motion artifacts, talking, lip-sync, voice, music, sound effects, subtitles, captions, or text overlays.
