subject_definitions: <Subject 1> is the young woman in <Picture 2>: fair skin, a small oval face, dark soft eyebrows and pale pink lips, long straight black hair with light airy bangs, the rest of her hair gathered into a half-up bun at the back of her head fixed with small white flower ornaments and one long strand of tiny white beads hanging beside her ear; she wears a pale celadon-green hanfu with a crossed white inner collar, a thin pale sash at the waist, extremely wide sheer layered sleeves, and a long flowing skirt that reaches the floor. <Picture 2> is a character turnaround sheet showing the SAME single person from three angles (front, side and back); the three figures are one character, never a group and never three different people. It is the identity and costume anchor for <Subject 1>, including her back view: long black hair falling straight down her back over the pale green hanfu, the half-up bun with the white flower ornaments, the wide sheer sleeves and the long trailing skirt. <Subject 2> is the celestial palace corridor in <Picture 1>: an ultra-realistic white-jade open colonnade whose regularly spaced round pillars are carved with coiling dragons picked out in gold, a polished white-jade floor with faint carved patterns, a white-jade balustrade of carved posts along the right side, dark beams and eaves with small golden wind bells hanging at the corners above, and beyond the balustrade a sea of clouds with distant multi-eaved palace roofs and a few cranes. <Picture 1> is the first frame of [Shot 1] and the fixed background anchor of the whole video: that medium shot of the corridor with warm golden sky light streaming in diagonally from the right. summary: [keyframe completion + reference generation] The target video is one continuous 10.8-second locked-off shot inside <Subject 2>, the celestial palace white-jade corridor whose opening frame is <Picture 1>; <Subject 1> is not yet in frame at the start, then she appears in the middle distance with her back to the camera and walks slowly away down the corridor. retention_analysis: <Picture 1> ([Shot 1] first frame; corridor background throughout [Shot 1]): fully_preserved - the jade pillars with their gold dragon carvings, the polished floor, the balustrade, the eaves and wind bells, the cloud sea and the warm golden light from the right stay exactly as in <Picture 1>. <Subject 1> (appears in [Shot 1]): fully_preserved - her long black hair, the white flower hair ornaments and bead tassel, the pale celadon hanfu with the white inner collar, the pale sash, the sheer wide sleeves and the long skirt. <Subject 2> (the corridor, throughout [Shot 1]): fully_preserved - the corridor is a fixed background that never moves, deforms, melts or changes. detailed_description: Photorealistic live-action wuxia-fantasy cinematography, ultra-realistic, mid-telephoto compressed perspective, shallow depth of field, Kodak Vision3 500T film texture with deep cyan shadows and warm gold highlights, fine organic film grain, soft-focus cinematic quality; the camera is locked off and never drifts, pans, tilts, zooms or cuts. [Shot 1] The shot begins exactly on <Picture 1>: the medium shot down the white-jade corridor, dragon-carved pillars receding in regular rhythm on both sides, the carved balustrade and the sea of clouds on the right, distant multi-eaved palaces half hidden in the clouds, warm golden sky light streaming in diagonally from the right. From 00:00.000 to 00:02.000 the corridor is empty: thin mist drifts slowly in from outside the colonnade; bright light spots keep flowing and shifting across the polished jade floor tiles as the warm golden light from the right moves gently; fine dust particles float and drift slowly in the air; the wind bells on the eaves sway very gently; far away a few cranes glide slowly across the sky, and once a crane is obscured by the architecture it does not reappear; beyond the balustrade the sea of clouds rolls and churns in slow heavy billows while the distant palaces stay half hidden. From 00:02.000 to 00:10.833 <Subject 1> appears from behind the nearer pillar on the left side of the corridor at middle distance, seen only from behind with her back squarely to the camera: long black hair down her back, the half-up bun with white flower ornaments, the wide pale celadon sleeves and the long skirt. She pauses for one breath, then walks forward away from the camera along the left half of the corridor with a graceful, feminine gait: small, even, unhurried steps, an upright calm carriage, a soft hip-led sway, the long skirt and wide sheer sleeves swaying gently with each step, the white bead tassel and flower ornaments swinging slightly, her hair moving a little; she never turns toward the camera, never stops, never runs. The mist, the flowing light spots, the floating dust, the gently swaying wind bells, the distant cranes and the rolling sea of clouds continue unchanged for the whole shot, and the architecture stays perfectly still. overall_soundscape: A soft steady high-altitude wind; the golden wind bells on the eaves give an occasional faint chime; a distant crane calls once; light cloth footfalls on jade and the soft rustle of silk sleeves are audible as she walks. non_diegetic_music: N/A
