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 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: [reference generation] The target video is the second 10.8-second part of a single continuous locked-off shot inside <Subject 2>, the celestial palace white-jade corridor; it continues seamlessly from the previous part, with <Subject 1> still seen only from behind, walking slowly away from the camera on the left half of the corridor, deeper into the colonnade. retention_analysis: <Picture 1> (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 continues seamlessly from the final frame of the previous part, with the identical corridor, the identical framing, the identical golden light on the right and the identical colour grade: no cut, no jump, no reset. <Subject 1> is already in frame at middle distance on the left half of the corridor, still seen only from behind with her back squarely to the camera, caught mid-stride; she keeps walking forward away from the camera at exactly the same slow, even, unhurried pace with a graceful feminine gait: an upright calm carriage, a soft hip-led sway, the long pale celadon skirt and the wide sheer sleeves swaying gently with each step, the white bead tassel and flower ornaments swinging slightly, her long black hair moving a little, never turning toward the camera, never stopping, never running. She moves steadily deeper down the colonnade between the dragon-carved jade pillars, staying on the left half of the corridor and inside the same frame. At the same time every ambient motion continues exactly as before: thin mist keeps drifting in slowly 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 multi-eaved palaces stay half hidden in the clouds. The architecture stays perfectly still. overall_soundscape: The same soft steady high-altitude wind continues; the golden wind bells on the eaves chime faintly now and then; light cloth footfalls on jade and the soft rustle of silk sleeves keep time with her steps. non_diegetic_music: N/A
