subject_definitions:
<Subject 1> is the young woman whose visual identity is defined by <Picture 1>: shoulder-length straight black hair, a slender build, natural fair skin, and a friendly neutral expression. Preserve her face, hairstyle, and body exactly as shown; only her outfit, pose, motion, and framing change in the target video.
<Picture 1> is the character reference frame for <Subject 1>, showing her face, hairstyle, and body in a neutral standing pose, wearing a plain grey t-shirt and black leggings that do not appear in the target video.
<Picture 2> is the garment reference image: a fitted red qipao-style dress with gold trim embroidery and a side slit, laid flat with no person wearing it. Only its garment attributes (silhouette, color, fabric, trim, cut) transfer onto <Subject 1>; no other content of this image appears in the target video.
<Video 1> is the reference choreography clip. It defines the dance structure, phrasing, and camera rhythm that the target video follows; it is not a visual identity source, and none of its performer, background, or imagery appears in the target video.
<Audio 1> is the background music track carried on <Video 1>, reused verbatim as the music bed of the target video. It contains no speech.

summary:
[reference generation + attribute transfer + audio reuse] The target video shows <Subject 1>, now wearing the outfit transferred from <Picture 2>, performing a lively hip-hop inspired routine with hip sways and raised-arm turns in a vertical studio setting, following the pacing and camera rhythm established in <Video 1>, with the music of <Audio 1> reused as its track.

retention_analysis:
<Subject 1> (appears in [Shot 1]): fully_preserved - her face, hairstyle, and body are retained unchanged throughout; her outfit changes to the garment shown in <Picture 2>.
<Picture 1>: fully_preserved - it supplies the face, hairstyle, and body of <Subject 1> and the opening framing of the shot.
<Picture 2>: attribute_transfer - only the garment's silhouette, color, fabric, and trim transfer onto <Subject 1>; the image itself does not appear.
<Video 1>: weak_reference - only the choreography phrasing and the camera rhythm are referenced; no performer, background, or imagery from it is retained.
<Audio 1>: fully_copy - the music track is reused verbatim as the non-diegetic music bed.

detailed_description:
A vibrant, mobile-first vertical dance video with warm, glossy studio lighting, saturated color, and a clean contemporary look sustained from the first frame to the last. [Shot 1] The shot begins from <Picture 1>, with <Subject 1> now wearing the outfit transferred from <Picture 2>. She stands centered in a medium-full vertical frame against a softly lit seamless backdrop that falls off into gentle shadow toward the edges. A warm key light sits slightly camera-left, a cooler rim light separates her shoulders and hair from the background, and a soft fill keeps her face evenly exposed. She begins in a relaxed neutral stance, weight settled on her back foot, hands loose at her sides, chin level with the lens. On the first musical accent she starts a lively hip-hop inspired routine with hip sways and raised-arm turns, and the routine unfolds continuously from there with no cut. Her weight transfers smoothly from foot to foot on the beat, hips leading each transfer and shoulders following a fraction behind, so the movement reads as one connected chain rather than a series of separate poses. Her arms trace clean, unhurried arcs that extend fully at the peak of each phrase and soften on the release, wrists relaxed and fingers naturally extended. Between phrases she adds small directional changes: a quarter turn away from the lens and back, a step that closes distance with the camera, a shift of gaze that returns to the lens on the downbeat. The camera holds a Static Shot through the opening beats, then performs a slow Push In with small amplitude at slow speed, tightening from medium-full to medium while keeping her head and hands inside the frame at every point of the routine. Her expression stays confident and playful, with a light smile and eyes that meet the lens at the end of each phrase. The fabric of the transferred outfit swings and settles naturally with each step, turn, and arm extension, and her hair carries the momentum of her head movement half a beat behind it. The pacing, phrasing, and camera rhythm follow the structure established in <Video 1>: the routine builds energy through the middle of the clip, reaches its widest and fastest movement around the two-thirds point, then settles back toward stillness. The closing beats return her to a stance, framing, and lighting that closely match her opening position, so the clip loops cleanly for repeated live playback. No text, graphics, watermarks, or overlays appear anywhere in the frame at any point.

overall_soundscape:
Soft ambient room tone of an enclosed studio sits under the music, with faint fabric rustle as <Subject 1> moves and light rhythmic footfall on the floor as her weight transfers. No speech, no crowd, and no off-screen sound events occur at any point.

non_diegetic_music:
An upbeat instrumental track drives the routine from the first frame to the last; its tempo, instrumentation, and dynamics are copied verbatim from <Audio 1>. Its accents align with the weight transfers and arm extensions of <Subject 1>, and its energy build through the middle of the clip matches the build in her movement.
