+AWM_PROXY_CONTROL. One visual reference accompanies this text. <Video 1> is the conditioning proxy video: treat it as the exact spatiotemporal reference for where every subject is, how large it is and how it moves, but never as an appearance template or literal target geometry. Each subject's position and motion come from <Video 1>. Every subject's appearance comes from the text below, rendered consistently in the worldview and art direction it describes. The whole take is rendered in this style, from the first frame to the last: Photorealistic rendering with real-camera optics: shallow depth of field that separates the sharp near subject from a softly blurred background, diffuse low-contrast light with soft glowing specular highlights and lifted shadows, cool desaturated blue-grey grading with muted warm amber accents, misty atmospheric perspective softening the distance, wet or glossy reflective surfaces where the setting allows and finely textured matte materials elsewhere, natural human anatomy; no proxy colours, wireframes, block figures or game UI.
+
+Human proxies in <Video 1> provide only framewise root position, occupied scale (in this representation the box is the entity's exact extent), and whole-body root orientation, which are exact and must be followed precisely. They carry no information about character appearance and do not represent identity, face, hairstyle, clothing, materials, colors, visual effects, anatomy, bones, joints, limb articulation, detailed posture, torso or head pose, hand pose, action phase, or physical contact. Reconstruct each character's appearance from the text, and reconstruct articulated motion from the timestamped text. Never reproduce a human proxy as a skeleton, stick figure, mannequin, node-connected body, or exposed rig. Left and right refer to each person's own body unless explicitly stated as screen direction. On every human, vehicle and animal proxy in <Video 1> the white face is the front of that entity's body: white there is a direction code, never an object, a material or a light, and it must not be painted. The hex colour tags used below only say which proxy stands for which subject: they are identity codes, never colours or materials of the result. Wherever <Video 1> shows a subject only as a flat single-colour shape, that shape is likewise only a placeholder for position, size and motion: draw the complete real person, animal or object the text names in its place.
+
+Vehicle proxies in <Video 1> provide only framewise position, trajectory, body heading, rotation, and accurate overall length, width, height, and occupied scale; these anchors should be followed closely. They carry no information about vehicle appearance. Never reproduce a vehicle proxy as a wireframe vehicle, cage frame, tubular skeleton, exposed chassis, or low-poly proxy car. Vehicle identity, type, design details, materials, colors, and visual effects are defined by the text.
+
+Roads, terrain, buildings, relative depth, rough scale, and layout in <Video 1> provide denser but still approximate structural cues. Conditioning colors, proxy geometry, node markers, rigging structures, and other visualization artifacts must never appear in the final video.
+
+When sources conflict, resolve in this order: (1) geometry, camera, position and motion follow <Video 1>; (2) the worldview, art direction and overall style, and every subject's identity, appearance and materials, follow the text; (3) the timestamped text defines the concrete events, actions and rewrite targets within those constraints.
+
+Clip contract: this clip is the very beginning of the take - nothing precedes it. The first frame of the target reproduces frame 0 of <Video 1> in the appearance the text describes, and the clip continues directly from it while performing the timestamped actions.
+
+subject_definitions:
+<Video 1> is the conditioning proxy video of the same 5-second shot (its role is fixed by the control block above). The clip contains exactly 4 human proxies standing for <Subject 1> (the protagonist), <Subject 5> (independently moving adult participant 1), <Subject 6> (independently moving adult participant 2), <Subject 7> (the person pushing the wheeled handcart) and 2 object proxies standing for <Subject 3> (the wheeled handcart), <Subject 4> (the wheeled handcart); nothing else in <Video 1> is a person or an interaction object.
+<Subject 1> is the protagonist; in <Video 1> the human proxy tagged #366ef7; use the target appearance described below.
+<Subject 2> is the environment and its fixed spatial arrangement: A narrow old-town market with stone facades, stalls, awnings and handcarts. Realize every recorded structure, terrain feature, body of water, vehicle and interaction object with plausible materials appropriate to this setting. Vehicles and animals in this shot: A second wheeled handcart, similar in design to the first, located in the middle right of the frame, slightly further away - at the start of the clip its front toward the camera. A wheeled handcart with a wooden frame and metal wheels, positioned in the lower centre of the frame, appearing sturdy and utilitarian - at the start of the clip its front away from the camera. In <Video 1> the same environment layout is represented by flat semantic-colour proxy geometry: approximate structural cues for layout, relative depth and rough scale, never target materials or conditioning colours.
+<Subject 3> is the wheeled handcart; in <Video 1> the object proxy tagged #a7f736; use the target appearance described below.
+<Subject 4> is the wheeled handcart; in <Video 1> the object proxy tagged #6636f7; use the target appearance described below.
+<Subject 5> is independently moving adult participant 1; in <Video 1> the human proxy tagged #f736df that starts on the right of the frame; use the target appearance described below.
+<Subject 6> is independently moving adult participant 2; in <Video 1> the human proxy tagged #36f7d6 that starts on the right of the frame; use the target appearance described below.
+<Subject 7> is the person pushing the wheeled handcart; in <Video 1> the human proxy tagged #f79e36 that starts on the right of the frame; use the target appearance described below.
+
+summary:
+[reference generation] Generate a 5.00-second continuous shot in <Subject 2> of <Subject 1> pushing a handcart forward around a gentle bend and releasing the handle, involving <Subject 3> and <Subject 4> and <Subject 5> and <Subject 6> and <Subject 7>. Use <Video 1> for layout, root motion, object trajectories, action timing and the camera path, and realize the scene with the detailed target materials below.
+
+retention_analysis:
+<Video 1> (whole-shot spatial and temporal structure): fully_preserved - geometry, camera, placement, root motion and object trajectories follow <Video 1> as a coarse spatiotemporal reference; appearance, limb articulation, detailed posture and physical contact are not encoded in the proxy.
+<Subject 1> (appears in [Shot 1]): partially_preserved - retain the proxy's framewise root position, occupied scale, root orientation (the white face of the box is the front of the body), identity continuity and interaction timing from <Video 1>; reconstruct its appearance from the target materials below and its articulated motion from the timeline below.
+<Subject 2> (appears in [Shot 1]): partially_preserved - retain terrain, object layout and architectural forms from <Video 1>; surfaces, materials and lighting come from the target materials below.
+<Subject 3> (appears in [Shot 1]): partially_preserved - retain position, scale, trajectory, facing (the white face of its box is its front) and interaction role from <Video 1>; realize the object as seen in the target materials below, one continuous object throughout.
+<Subject 4> (appears in [Shot 1]): partially_preserved - retain position, scale, trajectory, facing (the white face of its box is its front) and interaction role from <Video 1>; realize the object as seen in the target materials below, one continuous object throughout.

+detailed_description:
+Photorealistic rendering with real-camera optics: shallow depth of field that separates the sharp near subject from a softly blurred background, diffuse low-contrast light with soft glowing specular highlights and lifted shadows, cool desaturated blue-grey grading with muted warm amber accents, misty atmospheric perspective softening the distance, wet or glossy reflective surfaces where the setting allows and finely textured matte materials elsewhere, natural human anatomy; no proxy colours, wireframes, block figures or game UI.
+[Shot 1] <Subject 2>, the setting: A narrow old-town market with stone facades, stalls, awnings and handcarts. Realize every recorded structure, terrain feature, body of water, vehicle and interaction object with plausible materials appropriate to this setting. Vehicles and animals in this shot: A second wheeled handcart, similar in design to the first, located in the middle right of the frame, slightly further away - at the start of the clip its front toward the camera. A wheeled handcart with a wooden frame and metal wheels, positioned in the lower centre of the frame, appearing sturdy and utilitarian - at the start of the clip its front away from the camera. <Subject 1>, the protagonist, has the following target appearance: A tourist with curly copper hair, wearing a coral floral shirt, beige shorts, and sandals, standing in the middle centre of the frame, seen only from behind - at the start of the clip facing away from the camera; keep this identity and outfit consistent throughout the shot. <Subject 3> is the wheeled handcart, realized with the materials above. <Subject 4> is the wheeled handcart, pushed by <Subject 7> who walks directly behind it with both hands on its handle - the cart never moves on its own and the two move together as one unit, realized with the materials above. <Subject 5> (independently moving adult participant 1) is a street vendor with grey-streaked black hair, wearing a khaki apron over a sage tee, tan chinos, and rubber clogs, standing in the middle right of the frame - at the start of the clip facing toward the camera, and keeps exactly this appearance. <Subject 6> (independently moving adult participant 2) is a student with shoulder-length ash-brown hair, wearing a maroon hoodie, indigo denim jeans, and ivory canvas sneakers, standing in the middle far right of the frame, seen only from behind - at the start of the clip facing away from the camera, and keeps exactly this appearance. <Subject 7> (the person pushing the wheeled handcart) is a bicycle courier with cropped black hair, wearing a mustard windbreaker, slate cargo shorts, and ivory sneakers, standing in the middle right of the frame, slightly behind the street vendor - at the start of the clip facing toward the camera, and keeps exactly this appearance. All people keep the same face, build and clothing throughout, with clothing folds responding naturally to movement. The action follows <Video 1> according to this timeline: From 00:00.000 to 00:00.967, the protagonist steps up to the handcart and takes hold of its handle; independently moving adult participant 1 moves about half a metre along its route; independently moving adult participant 2 moves about a metre along its route; independently moving adult participant 3 moves about a metre along its route; the cart moves about a metre along its route. From 00:00.967 to 00:04.067, the protagonist pushes the handcart forward around the gentle bend; the protagonist moves about 5 metres along its route; the cart moves about 5 metres along its route; independently moving adult participant 1 moves about one and a half metres along its route; independently moving adult participant 2 moves about 3 metres along its route; independently moving adult participant 3 moves about 3 metres along its route; the cart moves about 3 metres along its route. From 00:04.067 to 00:05.000, the protagonist lets go of the handle and the handcart stays where it stopped; independently moving adult participant 2 moves about a metre along its route; independently moving adult participant 3 moves about a metre along its route; the cart moves about a metre along its route. Recorded relations: the protagonist pushes <Subject 3> from 00:00.967 to 00:04.067. <Subject 3> is one continuous object throughout and comes to rest about a metre from the protagonist. <Subject 4> is one continuous object throughout and ends the clip about 3 metres from the protagonist. The protagonist in the foreground covers independently moving adult participant 1 from about 3.1 s to 5.0 s; the wheeled handcart in the foreground covers independently moving adult participant 1 from about 3.1 s to 3.4 s; the protagonist in the foreground covers independently moving adult participant 3 from about 2.7 s to 3.0 s. Keep the reference's fixed 53-degree vertical field of view. Preserve the single take and its pacing, without cuts or a new camera path. Keep world geometry, object identities and materials stable throughout the camera movement; reveal newly visible surfaces with the same layout and appearance; introduce no extra people or foreground obstacles. Rendering style, stated again because it governs every frame: Photorealistic rendering with real-camera optics: shallow depth of field that separates the sharp near subject from a softly blurred background, diffuse low-contrast light with soft glowing specular highlights and lifted shadows, cool desaturated blue-grey grading with muted warm amber accents, misty atmospheric perspective softening the distance, wet or glossy reflective surfaces where the setting allows and finely textured matte materials elsewhere, natural human anatomy; no proxy colours, wireframes, block figures or game UI. No interface overlays, captions, watermarks, dialogue or music.
