Nearby vehicles still use the original skill's near-plane wireframe fallback. The pale white patches behind doors are consistent with the white front-face overlay.",

+AWM_PROXY_CONTROL. Two visual references accompany 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. <Picture 1> is the global RGB anchor image: it defines identity and appearance, never motion. <Picture 1> is the ABSOLUTE standard for the worldview, art direction and overall style of the entire take, and on worldview, art direction and style it outranks even the description below. It provides NOTHING about any later frame's camera, composition, motion or interactions. Each subject's position and motion come from <Video 1>. A subject's appearance follows <Picture 1> when that subject is visible in it; subjects not visible in <Picture 1> take their appearance from the text, rendered consistently in <Picture 1>'s worldview and art direction.
+
+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 <Picture 1> and 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 <Picture 1> and 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 follow <Picture 1> absolutely - above the description below; identity, appearance and materials follow <Picture 1> for subjects visible in it, and follow the text for subjects not visible in it; (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. <Picture 1> is the global appearance anchor for the whole take, and the first frame of the target is locked to this exact image: the clip begins at precisely this visual state - identities, appearance, materials, art direction, lighting, camera framing and layout - and continues directly from it while performing the timestamped actions. Do not restart, redesign or re-interpret any identity.
+
+Camera: this is a first-person take seen through the protagonist's own eyes. The camera path of <Video 1> is the protagonist's head motion; no proxy of the protagonist is drawn in <Video 1> and the protagonist is never shown as a figure. Only the protagonist's own hands, forearms or a hand-held item may enter the lower edge of the frame when the timestamped text says they reach, hold, push or hand over something.
+
+subject_definitions:
+<Picture 1> is the first frame of [Shot 1]: the photoreal opening frame of the target video, showing a view from the back of a wooden cart looking down a wet cobblestone street in a misty old town, where a man in an apron walks on the left, a woman pushes a cart in the center, and a man in a hat walks away on the right, exactly as they must appear at 00:00.000.
+<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 3 human proxies standing for <Subject 5> (independently moving adult participant 1), <Subject 6> (independently moving adult participant 2), <Subject 7> (independently moving adult participant 3) 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, the camera wearer: this is a first-person shot seen through this person's own eyes, so the camera path of <Video 1> is this person's head motion; no box or figure of this person is drawn in <Video 1> (the legend colour #366ef7 of this person therefore never appears) and none is visible in <Picture 1>. Never draw this person as a figure in front of the camera; only this person's own hands, forearms or a hand-held item may enter the lower edge of the frame when the timeline says they reach, hold, push or hand over something.
+<Subject 2> is the environment and its fixed spatial arrangement: in <Picture 1> a narrow cobblestone street glistening with rain and puddles, flanked by grassy verges and large leafy trees. On the left, a wooden market stall with a flat roof stands near a stone wall. On the right, a black iron streetlamp stands near a large tree trunk. In the background, ochre and beige stone buildings with tiled roofs fade into a thick, cool-toned mist. The sky is a pale, overcast grey-blue; 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 <Picture 1> a wooden handcart with a slatted box bed and four spoked wheels, positioned in the immediate foreground, viewed from behind; in <Video 1> the object proxy tagged #a7f736, whose white face is its front.
+<Subject 4> is the wheeled handcart: in <Picture 1> a wooden handcart with a slatted box bed and spoked wheels, being pushed by the woman in the center of the street; in <Video 1> the object proxy tagged #6636f7, whose white face is its front.
+<Subject 5> is independently moving adult participant 1: in <Picture 1> a man with dark hair and a beard, wearing a sage green t-shirt, a tan apron, and tan trousers, walking forward on the left side of the street; in <Video 1> the human proxy tagged #f736df that starts on the left of the frame, whose white face is its front.
+<Subject 6> is independently moving adult participant 2: in <Picture 1> a man wearing a straw hat, a salmon pink patterned short-sleeved shirt, and beige shorts, walking away from the camera on the right side of the street; in <Video 1> the human proxy tagged #36f7d6, whose white face is its front.
+<Subject 7> is independently moving adult participant 3: in <Picture 1> a woman with dark hair, wearing a navy long-sleeved top and white trousers, pushing a wooden handcart in the center of the street; in <Video 1> the human proxy tagged #f79e36, whose white face is its front.
+
+summary:
+[keyframe completion + reference generation] Starting exactly from <Picture 1> as the first frame of [Shot 1], generate a 5.00-second continuous first-person shot in <Subject 2>, seen through the eyes of <Subject 1>, who is 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 keep the appearance, materials and lighting established in <Picture 1>.
+
+retention_analysis:
+<Picture 1> ([Shot 1] first frame): fully_preserved - the first frame of the target video reproduces this image exactly, including every person's appearance, the objects, the scene layout, materials, lighting and framing; later frames evolve continuously from it.
+<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> (camera wearer, never in frame): partially_preserved - retain the camera path of <Video 1> as this person's own head motion and the interaction timing of the timeline; the body stays outside the frame for the whole shot.
+<Subject 2> (appears in [Shot 1]): partially_preserved - retain terrain, object layout and architectural forms from <Video 1>; surfaces, materials and lighting come from <Picture 1>.
+<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 <Picture 1>, 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 <Picture 1>, one continuous object throughout.
+<Subject 5> (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 <Picture 1> and its articulated motion from the timeline below.
+<Subject 6> (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 <Picture 1> and its articulated motion from the timeline below.
+<Subject 7> (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 <Picture 1> and its articulated motion from the timeline below.
+
+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] The shot opens exactly on <Picture 1> and evolves continuously from that frame. <Subject 2>, the setting, is a narrow cobblestone street glistening with rain and puddles, flanked by grassy verges and large leafy trees. On the left, a wooden market stall with a flat roof stands near a stone wall. On the right, a black iron streetlamp stands near a large tree trunk. In the background, ochre and beige stone buildings with tiled roofs fade into a thick, cool-toned mist. The sky is a pale, overcast grey-blue, keeping the spacing and sizes of <Video 1>. <Subject 1>, the protagonist, is the camera wearer and stays outside the frame: the whole shot is seen through this person's eyes, and whatever the timeline says this person does is experienced as camera motion, never shown as a figure. <Subject 3>, the wheeled handcart, is a wooden handcart with a slatted box bed and four spoked wheels, positioned in the immediate foreground, viewed from behind, as seen in <Picture 1>. <Subject 4>, the wheeled handcart, is a wooden handcart with a slatted box bed and spoked wheels, being pushed by the woman in the center of the street, as seen in <Picture 1>. <Subject 5>, independently moving adult participant 1, is a man with dark hair and a beard, wearing a sage green t-shirt, a tan apron, and tan trousers, walking forward on the left side of the street, as seen in <Picture 1>. <Subject 6>, independently moving adult participant 2, is a man wearing a straw hat, a salmon pink patterned short-sleeved shirt, and beige shorts, walking away from the camera on the right side of the street, as seen in <Picture 1>. <Subject 7>, independently moving adult participant 3, is a woman with dark hair, wearing a navy long-sleeved top and white trousers, pushing a wooden handcart in the center of the street, as seen in <Picture 1>. 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 half a metre along its route; independently moving adult participant 3 moves about a metre along its route; <Subject 4> 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; <Subject 3> moves about 5 metres along its route; independently moving adult participant 1 moves about 2 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; <Subject 4> 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 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; <Subject 4> 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. Keep the reference's fixed 75-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. No interface overlays, captions, watermarks, dialogue or music.

+AWM_PROXY_CONTROL. Two visual references accompany 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. <Picture 1> is the global RGB anchor image: it defines identity and appearance, never motion. <Picture 1> is the ABSOLUTE standard for the worldview, art direction and overall style of the entire take, and on worldview, art direction and style it outranks even the description below. It provides NOTHING about any later frame's camera, composition, motion or interactions. Each subject's position and motion come from <Video 1>. A subject's appearance follows <Picture 1> when that subject is visible in it; subjects not visible in <Picture 1> take their appearance from the text, rendered consistently in <Picture 1>'s worldview and art direction.
+
+Human proxies in <Video 1> provide only framewise root position, coarse occupied scale, and whole-body root orientation, which should be followed closely. The proxy figure keeps ONE fixed upright pose for the whole clip: that pose is not an action and carries no information about sitting, crouching, riding, reaching or any limb articulation. 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 <Picture 1> and 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.
+
+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 <Picture 1> and 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 follow <Picture 1> absolutely - above the description below; identity, appearance and materials follow <Picture 1> for subjects visible in it, and follow the text for subjects not visible in it; (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. <Picture 1> is the global appearance anchor for the whole take, and the first frame of the target is locked to this exact image: the clip begins at precisely this visual state - identities, appearance, materials, art direction, lighting, camera framing and layout - and continues directly from it while performing the timestamped actions. Do not restart, redesign or re-interpret any identity.
+
+Camera: this is a first-person take seen through the protagonist's own eyes. The camera path of <Video 1> is the protagonist's head motion; no proxy of the protagonist is drawn in <Video 1> and the protagonist is never shown as a figure. Only the protagonist's own hands, forearms or a hand-held item may enter the lower edge of the frame when the timestamped text says they reach, hold, push or hand over something.
+
+subject_definitions:
+<Picture 1> is the first frame of [Shot 1]: the photoreal opening frame of the target video, showing a view from the back of a wooden cart looking down a wet cobblestone street in a misty old town, where a man in an apron walks on the left, a woman pushes a cart in the center, and a man in a hat walks away on the right, exactly as they must appear at 00:00.000.
+<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 3 blue mannequin proxies standing for <Subject 5> (independently moving adult participant 1), <Subject 6> (independently moving adult participant 2), <Subject 7> (independently moving adult participant 3) 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, the camera wearer: this is a first-person shot seen through this person's own eyes, so the camera path of <Video 1> is this person's head motion; no box or figure of this person is drawn in <Video 1> and none is visible in <Picture 1>. Never draw this person as a figure in front of the camera; only this person's own hands, forearms or a hand-held item may enter the lower edge of the frame when the timeline says they reach, hold, push or hand over something.
+<Subject 2> is the environment and its fixed spatial arrangement: in <Picture 1> a narrow cobblestone street glistening with rain and puddles, flanked by grassy verges and large leafy trees. On the left, a wooden market stall with a flat roof stands near a stone wall. On the right, a black iron streetlamp stands near a large tree trunk. In the background, ochre and beige stone buildings with tiled roofs fade into a thick, cool-toned mist. The sky is a pale, overcast grey-blue; 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.

+
+summary:
+[keyframe completion + reference generation] Starting exactly from <Picture 1> as the first frame of [Shot 1], generate a 5.00-second continuous first-person shot in <Subject 2>, seen through the eyes of <Subject 1>, who is 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 keep the appearance, materials and lighting established in <Picture 1>.
+
+retention_analysis:
+<Picture 1> ([Shot 1] first frame): fully_preserved - the first frame of the target video reproduces this image exactly, including every person's appearance, the objects, the scene layout, materials, lighting and framing; later frames evolve continuously from it.
+<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> (camera wearer, never in frame): partially_preserved - retain the camera path of <Video 1> as this person's own head motion and the interaction timing of the timeline; the body stays outside the frame for the whole shot.
+<Subject 2> (appears in [Shot 1]): partially_preserved - retain terrain, object layout and architectural forms from <Video 1>; surfaces, materials and lighting come from <Picture 1>.
+<Subject 3> (appears in [Shot 1]): partially_preserved - retain position, scale, trajectory and interaction role from <Video 1>; realize the object as seen in <Picture 1>, one continuous object throughout.
+<Subject 4> (appears in [Shot 1]): partially_preserved - retain position, scale, trajectory and interaction role from <Video 1>; realize the object as seen in <Picture 1>, one continuous object throughout.
+<Subject 5> (appears in [Shot 1]): partially_preserved - retain the proxy's framewise root position, occupied scale, root orientation, identity continuity and interaction timing from <Video 1>; reconstruct its appearance from <Picture 1> and its articulated motion from the timeline below.
+<Subject 6> (appears in [Shot 1]): partially_preserved - retain the proxy's framewise root position, occupied scale, root orientation, identity continuity and interaction timing from <Video 1>; reconstruct its appearance from <Picture 1> and its articulated motion from the timeline below.
+<Subject 7> (appears in [Shot 1]): partially_preserved - retain the proxy's framewise root position, occupied scale, root orientation, identity continuity and interaction timing from <Video 1>; reconstruct its appearance from <Picture 1> and its articulated motion from the timeline below.
+
+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] The shot opens exactly on <Picture 1> and evolves continuously from that frame. <Subject 2>, the setting, is a narrow cobblestone street glistening with rain and puddles, flanked by grassy verges and large leafy trees. On the left, a wooden market stall with a flat roof stands near a stone wall. On the right, a black iron streetlamp stands near a large tree trunk. In the background, ochre and beige stone buildings with tiled roofs fade into a thick, cool-toned mist. The sky is a pale, overcast grey-blue, keeping the spacing and sizes of <Video 1>. <Subject 1>, the protagonist, is the camera wearer and stays outside the frame: the whole shot is seen through this person's eyes, and whatever the timeline says this person does is experienced as camera motion, never shown as a figure. <Subject 3>, the wheeled handcart, is a wooden handcart with a slatted box bed and four spoked wheels, positioned in the immediate foreground, viewed from behind, as seen in <Picture 1>. <Subject 4>, the wheeled handcart, is a wooden handcart with a slatted box bed and spoked wheels, being pushed by the woman in the center of the street, as seen in <Picture 1>. <Subject 5>, independently moving adult participant 1, is a man with dark hair and a beard, wearing a sage green t-shirt, a tan apron, and tan trousers, walking forward on the left side of the street, as seen in <Picture 1>. <Subject 6>, independently moving adult participant 2, is a man wearing a straw hat, a salmon pink patterned short-sleeved shirt, and beige shorts, walking away from the camera on the right side of the street, as seen in <Picture 1>. <Subject 7>, independently moving adult participant 3, is a woman with dark hair, wearing a navy long-sleeved top and white trousers, pushing a wooden handcart in the center of the street, as seen in <Picture 1>. 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 half a metre along its route; independently moving adult participant 3 moves about a metre along its route; <Subject 4> 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; <Subject 3> moves about 5 metres along its route; independently moving adult participant 1 moves about 2 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; <Subject 4> 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 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; <Subject 4> 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. Keep the reference's fixed 75-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. No interface overlays, captions, watermarks, dialogue or music.
+
+overall_soundscape:
+The rhythmic clatter of wooden wheels on wet cobblestones and the soft squelch of footsteps in puddles, accompanied by the distant, muffled murmur of a waking town.

+AWM_PROXY_CONTROL. Two visual references accompany 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. <Picture 1> is the global RGB anchor image: it defines identity and appearance, never motion. <Picture 1> is the ABSOLUTE standard for the worldview, art direction and overall style of the entire take, and on worldview, art direction and style it outranks even the description below. It provides NOTHING about any later frame's camera, composition, motion or interactions. Each subject's position and motion come from <Video 1>. A subject's appearance follows <Picture 1> when that subject is visible in it; subjects not visible in <Picture 1> take their appearance from the text, rendered consistently in <Picture 1>'s worldview and art direction.
+
+Human proxies in <Video 1> provide framewise root position, occupied scale, whole-body root orientation and COARSE limb articulation: the proxy figure's limbs move with the recorded joints, so follow the timing and direction of its limb motion closely, and take everything finer - hand pose, facial expression, grip and physical contact - from the timestamped text. They carry no information about character appearance and do not represent identity, face, hairstyle, clothing, materials, colors or visual effects. Reconstruct each character's appearance from <Picture 1> and the text. Never reproduce a human proxy as a block figure, 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.
+
+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 <Picture 1> and 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 follow <Picture 1> absolutely - above the description below; identity, appearance and materials follow <Picture 1> for subjects visible in it, and follow the text for subjects not visible in it; (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. <Picture 1> is the global appearance anchor for the whole take, and the first frame of the target is locked to this exact image: the clip begins at precisely this visual state - identities, appearance, materials, art direction, lighting, camera framing and layout - and continues directly from it while performing the timestamped actions. Do not restart, redesign or re-interpret any identity.
+
+Camera: this is a first-person take seen through the protagonist's own eyes. The camera path of <Video 1> is the protagonist's head motion; no proxy of the protagonist is drawn in <Video 1> and the protagonist is never shown as a figure. Only the protagonist's own hands, forearms or a hand-held item may enter the lower edge of the frame when the timestamped text says they reach, hold, push or hand over something.
+
+subject_definitions:
+<Picture 1> is the first frame of [Shot 1]: the photoreal opening frame of the target video, showing a view from the back of a wooden cart looking down a wet cobblestone street in a misty old town, where a man in an apron walks on the left, a woman pushes a cart in the center, and a man in a hat walks away on the right, exactly as they must appear at 00:00.000.
+<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 3 grey block-figure proxies standing for <Subject 5> (independently moving adult participant 1), <Subject 6> (independently moving adult participant 2), <Subject 7> (independently moving adult participant 3) 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, the camera wearer: this is a first-person shot seen through this person's own eyes, so the camera path of <Video 1> is this person's head motion; no box or figure of this person is drawn in <Video 1> and none is visible in <Picture 1>. Never draw this person as a figure in front of the camera; only this person's own hands, forearms or a hand-held item may enter the lower edge of the frame when the timeline says they reach, hold, push or hand over something.
+<Subject 2> is the environment and its fixed spatial arrangement: in <Picture 1> a narrow cobblestone street glistening with rain and puddles, flanked by grassy verges and large leafy trees. On the left, a wooden market stall with a flat roof stands near a stone wall. On the right, a black iron streetlamp stands near a large tree trunk. In the background, ochre and beige stone buildings with tiled roofs fade into a thick, cool-toned mist. The sky is a pale, overcast grey-blue; in <Video 1> the same environment layout is represented by untextured grey proxy geometry: approximate structural cues for layout, relative depth and rough scale, never target materials.
+<Subject 3> is the wheeled handcart: in <Picture 1> a wooden handcart with a slatted box bed and four spoked wheels, positioned in the immediate foreground, viewed from behind; in <Video 1> the plain grey proxy solid.
+<Subject 4> is the wheeled handcart: in <Picture 1> a wooden handcart with a slatted box bed and spoked wheels, being pushed by the woman in the center of the street; in <Video 1> the plain grey proxy solid.
+<Subject 5> is independently moving adult participant 1: in <Picture 1> a man with dark hair and a beard, wearing a sage green t-shirt, a tan apron, and tan trousers, walking forward on the left side of the street; in <Video 1> the grey block-figure proxy that starts on the left of the frame.
+<Subject 6> is independently moving adult participant 2: in <Picture 1> a man wearing a straw hat, a salmon pink patterned short-sleeved shirt, and beige shorts, walking away from the camera on the right side of the street; in <Video 1> the grey block-figure proxy.
+<Subject 7> is independently moving adult participant 3: in <Picture 1> a woman with dark hair, wearing a navy long-sleeved top and white trousers, pushing a wooden handcart in the center of the street; in <Video 1> the grey block-figure proxy.
+
+summary:
+[keyframe completion + reference generation] Starting exactly from <Picture 1> as the first frame of [Shot 1], generate a 5.00-second continuous first-person shot in <Subject 2>, seen through the eyes of <Subject 1>, who is 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, limb motion, object trajectories, action timing and the camera path, and keep the appearance, materials and lighting established in <Picture 1>.
+
+retention_analysis:
+<Picture 1> ([Shot 1] first frame): fully_preserved - the first frame of the target video reproduces this image exactly, including every person's appearance, the objects, the scene layout, materials, lighting and framing; later frames evolve continuously from it.
+<Video 1> (whole-shot spatial and temporal structure): fully_preserved - geometry, camera, placement, root motion, recorded limb motion and object trajectories follow <Video 1> as a coarse spatiotemporal reference; appearance, materials and surface detail are not encoded in the proxy.
+<Subject 1> (camera wearer, never in frame): partially_preserved - retain the camera path of <Video 1> as this person's own head motion and the interaction timing of the timeline; the body stays outside the frame for the whole shot.
+<Subject 2> (appears in [Shot 1]): partially_preserved - retain terrain, object layout and architectural forms from <Video 1>; surfaces, materials and lighting come from <Picture 1>.
+<Subject 3> (appears in [Shot 1]): partially_preserved - retain position, scale, trajectory and interaction role from <Video 1>; realize the object as seen in <Picture 1>, one continuous object throughout.
+<Subject 4> (appears in [Shot 1]): partially_preserved - retain position, scale, trajectory and interaction role from <Video 1>; realize the object as seen in <Picture 1>, one continuous object throughout.
+<Subject 5> (appears in [Shot 1]): partially_preserved - retain the proxy's framewise root position, occupied scale, root orientation, recorded limb motion, identity continuity and interaction timing from <Video 1>; reconstruct its appearance from <Picture 1> and render natural human articulation over the recorded block-figure motion.
+<Subject 6> (appears in [Shot 1]): partially_preserved - retain the proxy's framewise root position, occupied scale, root orientation, recorded limb motion, identity continuity and interaction timing from <Video 1>; reconstruct its appearance from <Picture 1> and render natural human articulation over the recorded block-figure motion.
+<Subject 7> (appears in [Shot 1]): partially_preserved - retain the proxy's framewise root position, occupied scale, root orientation, recorded limb motion, identity continuity and interaction timing from <Video 1>; reconstruct its appearance from <Picture 1> and render natural human articulation over the recorded block-figure motion.
+
+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] The shot opens exactly on <Picture 1> and evolves continuously from that frame. <Subject 2>, the setting, is a narrow cobblestone street glistening with rain and puddles, flanked by grassy verges and large leafy trees. On the left, a wooden market stall with a flat roof stands near a stone wall. On the right, a black iron streetlamp stands near a large tree trunk. In the background, ochre and beige stone buildings with tiled roofs fade into a thick, cool-toned mist. The sky is a pale, overcast grey-blue, keeping the spacing and sizes of <Video 1>. <Subject 1>, the protagonist, is the camera wearer and stays outside the frame: the whole shot is seen through this person's eyes, and whatever the timeline says this person does is experienced as camera motion, never shown as a figure. <Subject 3>, the wheeled handcart, is a wooden handcart with a slatted box bed and four spoked wheels, positioned in the immediate foreground, viewed from behind, as seen in <Picture 1>. <Subject 4>, the wheeled handcart, is a wooden handcart with a slatted box bed and spoked wheels, being pushed by the woman in the center of the street, as seen in <Picture 1>. <Subject 5>, independently moving adult participant 1, is a man with dark hair and a beard, wearing a sage green t-shirt, a tan apron, and tan trousers, walking forward on the left side of the street, as seen in <Picture 1>. <Subject 6>, independently moving adult participant 2, is a man wearing a straw hat, a salmon pink patterned short-sleeved shirt, and beige shorts, walking away from the camera on the right side of the street, as seen in <Picture 1>. <Subject 7>, independently moving adult participant 3, is a woman with dark hair, wearing a navy long-sleeved top and white trousers, pushing a wooden handcart in the center of the street, as seen in <Picture 1>. 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 half a metre along its route; independently moving adult participant 3 moves about a metre along its route; <Subject 4> 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; <Subject 3> moves about 5 metres along its route; independently moving adult participant 1 moves about 2 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; <Subject 4> 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 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; <Subject 4> 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. Keep the reference's fixed 75-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. No interface overlays, captions, watermarks, dialogue or music.
+
+overall_soundscape:
+The rhythmic clatter of wooden wheels on wet cobblestones and the soft squelch of footsteps in puddles, accompanied by the distant, muffled murmur of a waking town.
