+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 and animal 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.
+
+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.
+
+subject_definitions:
+<Picture 1> is the first frame of [Shot 1]: the opening frame of the target video, already rendered in the target art style of this take, showing a man in a mustard jacket walks down a wet suburban street accompanied by three ducks, 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 1 human proxy standing for <Subject 1> (the protagonist) and 3 object proxies standing for <Subject 3> (the small duck), <Subject 4> (the small duck), <Subject 5> (the small duck); nothing else in <Video 1> is a person or an interaction object.
+<Subject 1> is the protagonist: in <Picture 1> a man seen from behind, wearing a mustard jacket, grey shorts, white socks, and white sneakers. He has short black hair and is walking forward; in <Video 1> the human proxy tagged #366ef7, whose white face is its front.
+<Subject 2> is the environment and its fixed spatial arrangement: in <Picture 1> a residential street paved with dark, reflective asphalt that mirrors the figures and surroundings. The sky is overcast with grey clouds and rain is falling. On the left, there are houses with blue and purple siding, white window frames, and tall green hedges. On the right, a blue house with a front porch and steps sits behind a green lawn and trees. The scene is rendered with flat colors and clean lines; 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 small duck: in <Picture 1> a white duck with orange feet, walking on the right side of the street; in <Video 1> the object proxy tagged #a7f736, whose white face is its front.
+<Subject 4> is the small duck: in <Picture 1> a duck with grey and white feathers and a green head, walking in the middle of the street; in <Video 1> the object proxy tagged #f736df, whose white face is its front.
+<Subject 5> is the small duck: in <Picture 1> a duck with black and white feathers, walking on the left side of the street; in <Video 1> the object proxy tagged #36f7d6 that starts on the left of the frame, 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 shot in <Subject 2> of <Subject 1> walking along while ducks waddle nearby and turn together, 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 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> (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 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 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.
+
+detailed_description:
+Graphic non-photorealistic rendering, flat vector cartoon look: crisp geometric shapes, flat colour fills with no gradients, bold simplified figures and minimal outlines, drawn over the full 3D world so every recorded shape stays readable; 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 residential street paved with dark, reflective asphalt that mirrors the figures and surroundings. The sky is overcast with grey clouds and rain is falling. On the left, there are houses with blue and purple siding, white window frames, and tall green hedges. On the right, a blue house with a front porch and steps sits behind a green lawn and trees. The scene is rendered with flat colors and clean lines, keeping the spacing and sizes of <Video 1>. <Subject 1>, the protagonist, is a man seen from behind, wearing a mustard jacket, grey shorts, white socks, and white sneakers. He has short black hair and is walking forward, as seen in <Picture 1>. <Subject 3>, the small duck, is a white duck with orange feet, walking on the right side of the street, as seen in <Picture 1>. <Subject 4>, the small duck, is a duck with grey and white feathers and a green head, walking in the middle of the street, as seen in <Picture 1>. <Subject 5>, the small duck, is a duck with black and white feathers, walking on the left side of the street, as seen in <Picture 1>. The person keeps 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 00:04.567, the protagonist walks along the route while the ducks waddle alongside in a line; the protagonist moves about 3 metres along its route; <Subject 3> moves about 3 metres along its route; <Subject 4> moves about 3 metres along its route; <Subject 5> moves about 3 metres along its route. From 00:04.567 to 00:05.000, the protagonist slows down and watches the ducks as they turn together and waddle on. Recorded relations: the protagonist observes and accompanies <Subject 3> from 00:00.000 to 00:05.000; the protagonist observes and accompanies <Subject 4> from 00:00.000 to 00:05.000; the protagonist observes and accompanies <Subject 5> from 00:00.000 to 00:05.000; <Subject 4> and <Subject 5> follow <Subject 3> from 00:00.000 to 00:05.000. <Subject 3> is one continuous object throughout and comes to rest about 2 metres from the protagonist. <Subject 4> is one continuous object throughout and comes to rest about 3 metres from the protagonist. <Subject 5> is one continuous object throughout and comes to rest about 2 metres from the protagonist. Keep the reference's fixed 60-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. Ink and contour lines, flat fills and graphic shadow shapes belong to the drawn characters and objects of the target style; they never trace a proxy box, proxy edge or proxy silhouette and never reproduce the proxy's conditioning colours. No interface overlays, captions, watermarks, dialogue or music.
+
+overall_soundscape:
+The sound of steady rain falling and splashing on the wet pavement, accompanied by the soft squelching of footsteps and the quacking of ducks.

+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 and animal 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.
+
+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.
+
+subject_definitions:
+<Picture 1> is the first frame of [Shot 1]: the opening frame of the target video, already rendered in the target art style of this take, showing a man in a mustard jacket walks down a wet suburban street accompanied by three ducks, 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 1 blue mannequin proxy standing for <Subject 1> (the protagonist) and 3 object proxies standing for <Subject 3> (the small duck), <Subject 4> (the small duck), <Subject 5> (the small duck); nothing else in <Video 1> is a person or an interaction object.
+<Subject 1> is the protagonist: in <Picture 1> a man seen from behind, wearing a mustard jacket, grey shorts, white socks, and white sneakers. He has short black hair and is walking forward; in <Video 1> the blue mannequin proxy.
+<Subject 2> is the environment and its fixed spatial arrangement: in <Picture 1> a residential street paved with dark, reflective asphalt that mirrors the figures and surroundings. The sky is overcast with grey clouds and rain is falling. On the left, there are houses with blue and purple siding, white window frames, and tall green hedges. On the right, a blue house with a front porch and steps sits behind a green lawn and trees. The scene is rendered with flat colors and clean lines; 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 small duck: in <Picture 1> a white duck with orange feet, walking on the right side of the street; in <Video 1> the black solid duck proxy shape.
+<Subject 4> is the small duck: in <Picture 1> a duck with grey and white feathers and a green head, walking in the middle of the street; in <Video 1> the black solid duck proxy shape.
+<Subject 5> is the small duck: in <Picture 1> a duck with black and white feathers, walking on the left side of the street; in <Video 1> the black solid duck proxy shape that starts on the left of the frame.
+
+summary:
+[keyframe completion + reference generation] Starting exactly from <Picture 1> as the first frame of [Shot 1], generate a 5.00-second continuous shot in <Subject 2> of <Subject 1> walking along while ducks waddle nearby and turn together, 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 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> (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 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 position, scale, trajectory and interaction role from <Video 1>; realize the object as seen in <Picture 1>, one continuous object throughout.

+detailed_description:
+Graphic non-photorealistic rendering, flat vector cartoon look: crisp geometric shapes, flat colour fills with no gradients, bold simplified figures and minimal outlines, drawn over the full 3D world so every recorded shape stays readable; 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 residential street paved with dark, reflective asphalt that mirrors the figures and surroundings. The sky is overcast with grey clouds and rain is falling. On the left, there are houses with blue and purple siding, white window frames, and tall green hedges. On the right, a blue house with a front porch and steps sits behind a green lawn and trees. The scene is rendered with flat colors and clean lines, keeping the spacing and sizes of <Video 1>. <Subject 1>, the protagonist, is a man seen from behind, wearing a mustard jacket, grey shorts, white socks, and white sneakers. He has short black hair and is walking forward, as seen in <Picture 1>. <Subject 3>, the small duck, is a white duck with orange feet, walking on the right side of the street, as seen in <Picture 1>. <Subject 4>, the small duck, is a duck with grey and white feathers and a green head, walking in the middle of the street, as seen in <Picture 1>. <Subject 5>, the small duck, is a duck with black and white feathers, walking on the left side of the street, as seen in <Picture 1>. The person keeps 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 00:04.567, the protagonist walks along the route while the ducks waddle alongside in a line; the protagonist moves about 3 metres along its route; <Subject 3> moves about 3 metres along its route; <Subject 4> moves about 3 metres along its route; <Subject 5> moves about 3 metres along its route. From 00:04.567 to 00:05.000, the protagonist slows down and watches the ducks as they turn together and waddle on. Recorded relations: the protagonist observes and accompanies <Subject 3> from 00:00.000 to 00:05.000; the protagonist observes and accompanies <Subject 4> from 00:00.000 to 00:05.000; the protagonist observes and accompanies <Subject 5> from 00:00.000 to 00:05.000; <Subject 4> and <Subject 5> follow <Subject 3> from 00:00.000 to 00:05.000. <Subject 3> is one continuous object throughout and comes to rest about 2 metres from the protagonist. <Subject 4> is one continuous object throughout and comes to rest about 3 metres from the protagonist. <Subject 5> is one continuous object throughout and comes to rest about 2 metres from the protagonist. Keep the reference's fixed 60-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. Ink and contour lines, flat fills and graphic shadow shapes belong to the drawn characters and objects of the target style; they never trace a proxy box, proxy edge or proxy silhouette and never reproduce the proxy's conditioning colours. No interface overlays, captions, watermarks, dialogue or music.
+
+overall_soundscape:
+The sound of steady rain falling and splashing on the wet pavement, accompanied by the soft squelching of footsteps and the quacking of ducks.

+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 and animal 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.
+
+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.
+
+subject_definitions:
+<Picture 1> is the first frame of [Shot 1]: the opening frame of the target video, already rendered in the target art style of this take, showing a man in a mustard jacket walks down a wet suburban street accompanied by three ducks, 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 1 grey block-figure proxy standing for <Subject 1> (the protagonist) and 3 object proxies standing for <Subject 3> (the small duck), <Subject 4> (the small duck), <Subject 5> (the small duck); nothing else in <Video 1> is a person or an interaction object.
+<Subject 1> is the protagonist: in <Picture 1> a man seen from behind, wearing a mustard jacket, grey shorts, white socks, and white sneakers. He has short black hair and is walking forward; in <Video 1> the grey block-figure proxy.
+<Subject 2> is the environment and its fixed spatial arrangement: in <Picture 1> a residential street paved with dark, reflective asphalt that mirrors the figures and surroundings. The sky is overcast with grey clouds and rain is falling. On the left, there are houses with blue and purple siding, white window frames, and tall green hedges. On the right, a blue house with a front porch and steps sits behind a green lawn and trees. The scene is rendered with flat colors and clean lines; 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 small duck: in <Picture 1> a white duck with orange feet, walking on the right side of the street; in <Video 1> the plain grey proxy solid.
+<Subject 4> is the small duck: in <Picture 1> a duck with grey and white feathers and a green head, walking in the middle of the street; in <Video 1> the plain grey proxy solid.
+<Subject 5> is the small duck: in <Picture 1> a duck with black and white feathers, walking on the left side of the street; in <Video 1> the plain grey proxy solid that starts on the left of the frame.
+
+summary:
+[keyframe completion + reference generation] Starting exactly from <Picture 1> as the first frame of [Shot 1], generate a 5.00-second continuous shot in <Subject 2> of <Subject 1> walking along while ducks waddle nearby and turn together, 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 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> (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 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 position, scale, trajectory and interaction role from <Video 1>; realize the object as seen in <Picture 1>, one continuous object throughout.

+detailed_description:
+Graphic non-photorealistic rendering, flat vector cartoon look: crisp geometric shapes, flat colour fills with no gradients, bold simplified figures and minimal outlines, drawn over the full 3D world so every recorded shape stays readable; 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 residential street paved with dark, reflective asphalt that mirrors the figures and surroundings. The sky is overcast with grey clouds and rain is falling. On the left, there are houses with blue and purple siding, white window frames, and tall green hedges. On the right, a blue house with a front porch and steps sits behind a green lawn and trees. The scene is rendered with flat colors and clean lines, keeping the spacing and sizes of <Video 1>. <Subject 1>, the protagonist, is a man seen from behind, wearing a mustard jacket, grey shorts, white socks, and white sneakers. He has short black hair and is walking forward, as seen in <Picture 1>. <Subject 3>, the small duck, is a white duck with orange feet, walking on the right side of the street, as seen in <Picture 1>. <Subject 4>, the small duck, is a duck with grey and white feathers and a green head, walking in the middle of the street, as seen in <Picture 1>. <Subject 5>, the small duck, is a duck with black and white feathers, walking on the left side of the street, as seen in <Picture 1>. The person keeps 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 00:04.567, the protagonist walks along the route while the ducks waddle alongside in a line; the protagonist moves about 3 metres along its route; <Subject 3> moves about 3 metres along its route; <Subject 4> moves about 3 metres along its route; <Subject 5> moves about 3 metres along its route. From 00:04.567 to 00:05.000, the protagonist slows down and watches the ducks as they turn together and waddle on. Recorded relations: the protagonist observes and accompanies <Subject 3> from 00:00.000 to 00:05.000; the protagonist observes and accompanies <Subject 4> from 00:00.000 to 00:05.000; the protagonist observes and accompanies <Subject 5> from 00:00.000 to 00:05.000; <Subject 4> and <Subject 5> follow <Subject 3> from 00:00.000 to 00:05.000. <Subject 3> is one continuous object throughout and comes to rest about 2 metres from the protagonist. <Subject 4> is one continuous object throughout and comes to rest about 3 metres from the protagonist. <Subject 5> is one continuous object throughout and comes to rest about 2 metres from the protagonist. Keep the reference's fixed 60-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. Ink and contour lines, flat fills and graphic shadow shapes belong to the drawn characters and objects of the target style; they never trace a proxy box, proxy edge or proxy silhouette and never reproduce the proxy's conditioning colours. No interface overlays, captions, watermarks, dialogue or music.

+overall_soundscape:
+The sound of steady rain falling and splashing on the wet pavement, accompanied by the soft squelching of footsteps and the quacking of ducks.
