+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: Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; 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. There is no box, frame, glass panel, outline or coloured slab around or in front of any person, animal or object in the output; every figure stands directly in the scene.
+
+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, participant A), <Subject 3> (participant B), <Subject 4> (participant C), <Subject 5> (participant D); nothing else in <Video 1> is a person or an interaction object.
+<Subject 1> is the protagonist (participant A); in <Video 1> the human proxy tagged #366ef7; use the target appearance described below.
+<Subject 2> is the environment and its fixed spatial arrangement: Open, level grassland with fenced paddocks: long wooden rail fences run across the pasture, a large barn stands to one side, scattered trees dot the rolling ground and the grass stretches away to the horizon under an open sky. The people walk on the open grass between the fences. Preserve the reference spacing, fence lines, barn and tree positions and open walking routes. Use short green grass, weathered wooden rails, painted barn boards and leafy trees. In <Video 1> the same layout where purple blocks are buildings (walls, roofs and railings included), green low-poly shapes are trees, the sky is blue and the ground is dark grey; these solid colours are semantic class codes shared by every entity of a class, not materials; these shapes and colours are approximate structural cues for layout, relative depth and rough scale, never target materials.
+<Subject 3> is participant B; in <Video 1> the human proxy tagged #a7f736; use the target appearance described below.
+<Subject 4> is participant C; in <Video 1> the human proxy tagged #f736df; use the target appearance described below.
+<Subject 5> is participant D; in <Video 1> the human proxy tagged #36f7d6 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> walking across open grassland where the participants' routes cross from four directions, involving <Subject 3> and <Subject 4> and <Subject 5>. 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 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 4> (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 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 the target materials below and its articulated motion from the timeline below.

+detailed_description:
+Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; no proxy colours, wireframes, block figures or game UI.
+[Shot 1] <Subject 2>, the setting: Open, level grassland with fenced paddocks: long wooden rail fences run across the pasture, a large barn stands to one side, scattered trees dot the rolling ground and the grass stretches away to the horizon under an open sky. The people walk on the open grass between the fences. Preserve the reference spacing, fence lines, barn and tree positions and open walking routes. Use short green grass, weathered wooden rails, painted barn boards and leafy trees. <Subject 1>, the protagonist, has the following target appearance: The protagonist is participant A, a stocky adult with short sandy hair, wearing a plaid flannel shirt in royal blue and white, faded grey jeans and brown work boots. The other participants of the same recording are participant B, a slim adult with a long dark braid, wearing a knitted cardigan in bright lime green, a white T-shirt, beige trousers and tan ankle boots; participant C, a tall adult with short wavy auburn hair, wearing a quilted gilet in vivid magenta pink over a grey shirt, black trousers and dark rubber boots and participant D, an adult of medium build with closely cropped grey hair, wearing a cotton work shirt in bright turquoise, khaki trousers and brown leather boots; only those listed as subjects above appear in this view. Each person keeps one consistent face, build and outfit for the whole clip, no two people share the same outfit and nobody carries anything. <Subject 3> (participant B) is a slim adult with a long dark braid, wearing a knitted cardigan in bright lime green, a white T-shirt, beige trousers and tan ankle boots, and keeps exactly this appearance. <Subject 4> (participant C) is a tall adult with short wavy auburn hair, wearing a quilted gilet in vivid magenta pink over a grey shirt, black trousers and dark rubber boots, and keeps exactly this appearance. <Subject 5> (participant D) is an adult of medium build with closely cropped grey hair, wearing a cotton work shirt in bright turquoise, khaki trousers and brown leather boots, and keeps exactly this appearance. All people keep the same face, build and clothing throughout, with clothing folds responding naturally to movement. At the start of the clip <Subject 1> (the protagonist) stands in the centre of the middle part of the frame, about a third to half of the frame height, nearest to the camera, seen from behind, facing away from the camera; <Subject 3> (participant B) stands on the screen-right of the upper part of the frame, a small figure, in the far background, to the screen-right of <Subject 1>, seen from the front, facing toward the camera; <Subject 4> (participant C) stands on the screen-left of the upper part of the frame, a small figure, behind <Subject 5>, directly behind <Subject 1>, seen from the side, facing the screen-right; <Subject 5> (participant D) stands at the far screen-right edge of the middle part of the frame, about a third to half of the frame height, behind <Subject 1>, to the screen-right of <Subject 1>, partly cut off by the frame edge, seen from the side, facing the screen-left. The action follows <Video 1> according to this timeline: From 00:00.000 to 00:02.500, the participants walk toward an open patch of pasture along offset straight routes from different directions - participant A heading north, B south, C east and D west - so their routes converge on the crossing; the protagonist (participant A) moves about 3 metres along its route; participant B moves about 3 metres along its route; participant C moves about 3 metres along its route; participant D moves about 3 metres along its route. From 00:02.500 to 00:05.000, they cross through the middle with clearance, A passing closest to D and B passing closest to C, and each keeps walking straight on along their own direction, moving apart; the protagonist (participant A) moves about 3 metres along its route; participant B moves about 3 metres along its route; participant C moves about 3 metres along its route; participant D moves about 3 metres along its route. Participant D in the foreground covers the protagonist from about 3.9 s to 4.2 s; participant D in the foreground covers participant B from about 2.7 s to 3.6 s; the protagonist (participant A) in the foreground covers participant C from about 0.9 s to 2.3 s; participant D in the foreground covers participant C from about 3.3 s to 3.8 s. Keep the reference's recorded vertical field of view at every frame. 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: Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; no proxy colours, wireframes, block figures or game UI. No interface overlays, captions, watermarks, dialogue or music.

+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: Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; no proxy colours, wireframes, block figures or game UI.
+
+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 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. There is no box, frame, glass panel, outline or coloured slab around or in front of any person, animal or object in the output; every figure stands directly in the scene.
+
+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 blue mannequin proxies standing for <Subject 1> (the protagonist, participant A), <Subject 3> (participant B), <Subject 4> (participant C), <Subject 5> (participant D); nothing else in <Video 1> is a person or an interaction object.
+<Subject 1> is the protagonist (participant A); in <Video 1> the blue mannequin proxy; use the target appearance described below.
+<Subject 2> is the environment and its fixed spatial arrangement: Open, level grassland with fenced paddocks: long wooden rail fences run across the pasture, a large barn stands to one side, scattered trees dot the rolling ground and the grass stretches away to the horizon under an open sky. The people walk on the open grass between the fences. Preserve the reference spacing, fence lines, barn and tree positions and open walking routes. Use short green grass, weathered wooden rails, painted barn boards and leafy trees. In <Video 1> the same layout as green low-poly trees and black blocks on a dark grey ground under a blue sky; these shapes and colours are approximate structural cues for layout, relative depth and rough scale, never target materials.
+<Subject 3> is participant B; in <Video 1> the blue mannequin proxy; use the target appearance described below.
+<Subject 4> is participant C; in <Video 1> the blue mannequin proxy; use the target appearance described below.
+<Subject 5> is participant D; in <Video 1> the blue mannequin proxy 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> walking across open grassland where the participants' routes cross from four directions, involving <Subject 3> and <Subject 4> and <Subject 5>. 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, 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 the proxy's framewise root position, occupied scale, root orientation, 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 4> (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 the target materials below and its articulated motion from the timeline below.

+detailed_description:
+Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; no proxy colours, wireframes, block figures or game UI.
+[Shot 1] <Subject 2>, the setting: Open, level grassland with fenced paddocks: long wooden rail fences run across the pasture, a large barn stands to one side, scattered trees dot the rolling ground and the grass stretches away to the horizon under an open sky. The people walk on the open grass between the fences. Preserve the reference spacing, fence lines, barn and tree positions and open walking routes. Use short green grass, weathered wooden rails, painted barn boards and leafy trees. <Subject 1>, the protagonist, has the following target appearance: The protagonist is participant A, a stocky adult with short sandy hair, wearing a plaid flannel shirt in royal blue and white, faded grey jeans and brown work boots. The other participants of the same recording are participant B, a slim adult with a long dark braid, wearing a knitted cardigan in bright lime green, a white T-shirt, beige trousers and tan ankle boots; participant C, a tall adult with short wavy auburn hair, wearing a quilted gilet in vivid magenta pink over a grey shirt, black trousers and dark rubber boots and participant D, an adult of medium build with closely cropped grey hair, wearing a cotton work shirt in bright turquoise, khaki trousers and brown leather boots; only those listed as subjects above appear in this view. Each person keeps one consistent face, build and outfit for the whole clip, no two people share the same outfit and nobody carries anything. <Subject 3> (participant B) is a slim adult with a long dark braid, wearing a knitted cardigan in bright lime green, a white T-shirt, beige trousers and tan ankle boots, and keeps exactly this appearance. <Subject 4> (participant C) is a tall adult with short wavy auburn hair, wearing a quilted gilet in vivid magenta pink over a grey shirt, black trousers and dark rubber boots, and keeps exactly this appearance. <Subject 5> (participant D) is an adult of medium build with closely cropped grey hair, wearing a cotton work shirt in bright turquoise, khaki trousers and brown leather boots, and keeps exactly this appearance. All people keep the same face, build and clothing throughout, with clothing folds responding naturally to movement. At the start of the clip <Subject 1> (the protagonist) stands in the centre of the middle part of the frame, about a third to half of the frame height, nearest to the camera, seen from behind, facing away from the camera; <Subject 3> (participant B) stands on the screen-right of the upper part of the frame, a small figure, in the far background, to the screen-right of <Subject 1>, seen from the front, facing toward the camera; <Subject 4> (participant C) stands on the screen-left of the upper part of the frame, a small figure, behind <Subject 5>, directly behind <Subject 1>, seen from the side, facing the screen-right; <Subject 5> (participant D) stands at the far screen-right edge of the middle part of the frame, about a third to half of the frame height, behind <Subject 1>, to the screen-right of <Subject 1>, partly cut off by the frame edge, seen from the side, facing the screen-left. The action follows <Video 1> according to this timeline: From 00:00.000 to 00:02.500, the participants walk toward an open patch of pasture along offset straight routes from different directions - participant A heading north, B south, C east and D west - so their routes converge on the crossing; the protagonist (participant A) moves about 3 metres along its route; participant B moves about 3 metres along its route; participant C moves about 3 metres along its route; participant D moves about 3 metres along its route. From 00:02.500 to 00:05.000, they cross through the middle with clearance, A passing closest to D and B passing closest to C, and each keeps walking straight on along their own direction, moving apart; the protagonist (participant A) moves about 3 metres along its route; participant B moves about 3 metres along its route; participant C moves about 3 metres along its route; participant D moves about 3 metres along its route. Participant D in the foreground covers the protagonist from about 3.9 s to 4.2 s; participant D in the foreground covers participant B from about 2.7 s to 3.6 s; the protagonist (participant A) in the foreground covers participant C from about 0.9 s to 2.3 s; participant D in the foreground covers participant C from about 3.3 s to 3.8 s. Keep the reference's recorded vertical field of view at every frame. 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: Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; no proxy colours, wireframes, block figures or game UI. No interface overlays, captions, watermarks, dialogue or music.

+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: Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; no proxy colours, wireframes, block figures or game UI.
+
+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 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. There is no box, frame, glass panel, outline or coloured slab around or in front of any person, animal or object in the output; every figure stands directly in the scene.
+
+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 grey block-figure proxies standing for <Subject 1> (the protagonist, participant A), <Subject 3> (participant B), <Subject 4> (participant C), <Subject 5> (participant D); nothing else in <Video 1> is a person or an interaction object.
+<Subject 1> is the protagonist (participant A); in <Video 1> the grey block-figure proxy; use the target appearance described below.
+<Subject 2> is the environment and its fixed spatial arrangement: Open, level grassland with fenced paddocks: long wooden rail fences run across the pasture, a large barn stands to one side, scattered trees dot the rolling ground and the grass stretches away to the horizon under an open sky. The people walk on the open grass between the fences. Preserve the reference spacing, fence lines, barn and tree positions and open walking routes. Use short green grass, weathered wooden rails, painted barn boards and leafy trees. In <Video 1> the same layout as grey low-poly trees and blocks on a dark grey ground; these shapes and colours are approximate structural cues for layout, relative depth and rough scale, never target materials.
+<Subject 3> is participant B; in <Video 1> the grey block-figure proxy; use the target appearance described below.
+<Subject 4> is participant C; in <Video 1> the grey block-figure proxy; use the target appearance described below.
+<Subject 5> is participant D; in <Video 1> the grey block-figure proxy 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> walking across open grassland where the participants' routes cross from four directions, involving <Subject 3> and <Subject 4> and <Subject 5>. Use <Video 1> for layout, root motion, limb 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, 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> (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 the target materials below and render natural human articulation over the recorded block-figure motion.
+<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 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 the target materials below and render natural human articulation over the recorded block-figure motion.
+<Subject 4> (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 the target materials below and render natural human articulation over the recorded block-figure motion.
+<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 the target materials below and render natural human articulation over the recorded block-figure motion.
+
+detailed_description:
+Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; no proxy colours, wireframes, block figures or game UI.
+[Shot 1] <Subject 2>, the setting: Open, level grassland with fenced paddocks: long wooden rail fences run across the pasture, a large barn stands to one side, scattered trees dot the rolling ground and the grass stretches away to the horizon under an open sky. The people walk on the open grass between the fences. Preserve the reference spacing, fence lines, barn and tree positions and open walking routes. Use short green grass, weathered wooden rails, painted barn boards and leafy trees. <Subject 1>, the protagonist, has the following target appearance: The protagonist is participant A, a stocky adult with short sandy hair, wearing a plaid flannel shirt in royal blue and white, faded grey jeans and brown work boots. The other participants of the same recording are participant B, a slim adult with a long dark braid, wearing a knitted cardigan in bright lime green, a white T-shirt, beige trousers and tan ankle boots; participant C, a tall adult with short wavy auburn hair, wearing a quilted gilet in vivid magenta pink over a grey shirt, black trousers and dark rubber boots and participant D, an adult of medium build with closely cropped grey hair, wearing a cotton work shirt in bright turquoise, khaki trousers and brown leather boots; only those listed as subjects above appear in this view. Each person keeps one consistent face, build and outfit for the whole clip, no two people share the same outfit and nobody carries anything. <Subject 3> (participant B) is a slim adult with a long dark braid, wearing a knitted cardigan in bright lime green, a white T-shirt, beige trousers and tan ankle boots, and keeps exactly this appearance. <Subject 4> (participant C) is a tall adult with short wavy auburn hair, wearing a quilted gilet in vivid magenta pink over a grey shirt, black trousers and dark rubber boots, and keeps exactly this appearance. <Subject 5> (participant D) is an adult of medium build with closely cropped grey hair, wearing a cotton work shirt in bright turquoise, khaki trousers and brown leather boots, and keeps exactly this appearance. All people keep the same face, build and clothing throughout, with clothing folds responding naturally to movement. At the start of the clip <Subject 1> (the protagonist) stands in the centre of the middle part of the frame, about a third to half of the frame height, nearest to the camera, seen from behind, facing away from the camera; <Subject 3> (participant B) stands on the screen-right of the upper part of the frame, a small figure, in the far background, to the screen-right of <Subject 1>, seen from the front, facing toward the camera; <Subject 4> (participant C) stands on the screen-left of the upper part of the frame, a small figure, behind <Subject 5>, directly behind <Subject 1>, seen from the side, facing the screen-right; <Subject 5> (participant D) stands at the far screen-right edge of the middle part of the frame, about a third to half of the frame height, behind <Subject 1>, to the screen-right of <Subject 1>, partly cut off by the frame edge, seen from the side, facing the screen-left. The action follows <Video 1> according to this timeline: From 00:00.000 to 00:02.500, the participants walk toward an open patch of pasture along offset straight routes from different directions - participant A heading north, B south, C east and D west - so their routes converge on the crossing; the protagonist (participant A) moves about 3 metres along its route; participant B moves about 3 metres along its route; participant C moves about 3 metres along its route; participant D moves about 3 metres along its route. From 00:02.500 to 00:05.000, they cross through the middle with clearance, A passing closest to D and B passing closest to C, and each keeps walking straight on along their own direction, moving apart; the protagonist (participant A) moves about 3 metres along its route; participant B moves about 3 metres along its route; participant C moves about 3 metres along its route; participant D moves about 3 metres along its route. Participant D in the foreground covers the protagonist from about 3.9 s to 4.2 s; participant D in the foreground covers participant B from about 2.7 s to 3.6 s; the protagonist (participant A) in the foreground covers participant C from about 0.9 s to 2.3 s; participant D in the foreground covers participant C from about 3.3 s to 3.8 s. Keep the reference's recorded vertical field of view at every frame. 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: Realistic live-action footage of the place described below in natural light suited to it, with natural human anatomy and motion, believable scale, detailed physical materials and consistent shadows; no proxy colours, wireframes, block figures or game UI. No interface overlays, captions, watermarks, dialogue or music.
