 "prompt": "subject_definitions\n<Subject 1> is the young woman in <Picture 1>: long straight black hair with a centre part, dark navy school blazer with a gold crest, white shirt, navy-and-white striped tie. She is the only person in frame.\n<Picture 1> is the first frame of [Shot 1]; it defines the identity, the framing, the lighting and the whole background.\n\nsummary\n[reference generation] A single continuous 5-second take of <Subject 1> speaking to camera in a sweet, bright, youthful Chinese female voice.\n\nretention_analysis\n<Subject 1>: identity_fully_preserved - face, hairstyle, blazer, shirt, tie and crest stay identical to <Picture 1>.\n<Picture 1>: fully_preserved - the background, the framing, the lighting and the subject's position and scale come entirely from this image.\n\ndetailed_description\n[Shot 1] Vertical 9:16 close-up, chest up. She sits at the table holding a dark-red phone in her right hand and looks down at its screen, reading a fan's comment aloud; her eyes stay on the phone screen the whole time and she never looks up. She speaks slowly and carefully with a clear short pause.  One continuous take, no cut. The camera holds a static shot from a fixed tripod position and the lens does not move. No push in, no pull out, no truck, no pan, no tilt, no zoom, no tracking shot, no arc, no shake. THE BACKGROUND IS ENTIRELY DEFINED BY <Picture 1>: it is not described in this prompt, it must not be replaced, extended, re-framed, re-lit or explored, and no other part of the room may ever be shown. The subject's position and scale in the frame stay identical from the first frame to the last, and the background stays identical to <Picture 1>. A soft warm smile stays on her face. She says: <d>[Chinese] 我的资产就稳定在 A2 这个层级。</d>\n\noverall_soundscape\nQuiet indoor room tone, no extra layers.\n\nnon_diegetic_music\nN/A",
