High-five on the move, shot 2

subject_definitions:
<Subject 1> is the young woman in <Picture 2>, in her early twenties, with long thick copper-orange curly hair falling well past her shoulders, pale freckled skin, blue-grey eyes and a slim build, wearing a plain cream short-sleeved crew-neck t-shirt, a long dark iron cross pendant on a thin dark chain, blue denim jeans, a wide tan leather belt with a brass buckle, a small tan leather belt pouch on her right hip, dark braided rope bracelets on both wrists and thin silver rings. Only her face, hair, body and clothing are taken from <Picture 2>; the snow, cliffs, green aurora and wooden sailing ship behind her in that image are not part of the target video.
<Subject 2> is the block of Market Street in San Francisco photographed from directly overhead in <Picture 1>: a long straight run of the avenue with embedded steel streetcar rails and overhead trolley wires down its centre, a sheer dark glass tower filling the whole left side, a narrow grey stone building with a rounded corner and a taller cream-coloured tower behind it on the right, a low classical stone building with a columned portico at the far corner, young street trees in square planters along the brick-red sidewalks and white-striped crosswalks at the intersection. Only the street layout, building shapes, materials and colours are used; the overhead aerial viewpoint and map-like flattening of <Picture 1> are not retained, and the target video is filmed at street level.
<Subject 3> is the young woman in <Picture 3>, in her mid-twenties, with long dark-brown wavy hair, warm olive-tan skin, dark eyes and a wide open smile, wearing a white lace-trimmed cropped camisole with small buttons down the front and high-waisted khaki trousers.

summary:
[reference generation + keyframe completion] The target video opens on an exact replay of the closing 1.6 seconds of the preceding segment of the same unbroken take and carries straight on from it as <Subject 1> moves along the Market Street block defined by <Subject 2>, where <Subject 3> jogs in from the right, trades a line with her and high-fives her before peeling away, leaving <Subject 1> walking on alone.

retention_analysis:
<Subject 1> (appears in [Shot 1]): fully_preserved - her face, freckles, blue-grey eyes, long copper-orange curls, cream t-shirt, iron cross pendant, tan leather belt and belt pouch, denim jeans, braided rope bracelets and silver rings are retained exactly.
<Subject 2> (appears in [Shot 1]): partially_preserved - the streetcar rails and overhead wires, the sheer dark glass tower on the left, the grey stone building with its rounded corner, the cream tower behind it, the columned stone building at the corner, the young street trees in square planters and the brick-red paving are retained; the overhead aerial viewpoint is replaced by a street-level camera at chest height.
<Subject 3> (appears in [Shot 1]): fully_preserved - her long dark-brown wavy hair, olive-tan skin, dark eyes, open smile, white lace-trimmed cropped camisole and high-waisted khaki trousers are retained.

detailed_description:
The target video is photorealistic live-action in a naturalistic documentary-cinematic style, filmed on a stabilised gimbal with a 35mm-equivalent lens held at chest height, in clear late-afternoon San Francisco light, with no on-screen text and no subtitles anywhere.
[Shot 1] The segment opens on an exact replay of the closing moments of the preceding take and carries that motion straight through, so the join is invisible: the camera is already in front of <Subject 1>, facing back toward her and travelling backwards at exactly her walking speed, holding her centred and framed from mid-thigh up for the whole eight seconds with no cut. The camera holds its distance exactly for the entire segment and never pushes in, pulls out or zooms, so her height in the frame at the end is identical to her height in the frame at the start. She holds the exact body pose, head angle, gaze direction and facial expression carried in by the replayed opening frames, continuing them without any reset before moving into the actions below. <Subject 1>, the young woman with long copper-orange curls, the cream crew-neck t-shirt, the iron cross pendant, the tan leather belt with its small pouch and blue denim jeans, continues walking directly toward the lens on the same foot and at the same unhurried cadence she carries out of the replayed opening. She is now on the brick-red sidewalk of <Subject 2>, with the steel streetcar rails and overhead trolley wires running down the avenue behind her, the sheer dark glass tower rising the full height of frame on the left and the grey stone building with the rounded corner passing on the right. The low sun stays behind her up the avenue, rimming her curls in warm orange and laying her long shadow toward the camera. Just after the two-second mark, <Subject 3>, the young woman with long dark-brown wavy hair, olive-tan skin and a white lace-trimmed cropped camisole with high-waisted khaki trousers, comes jogging into frame from the right, cutting past a square tree planter to fall in alongside her. <Subject 1> (S1) registers her arrival with a flicker of recognition, then lets her face settle, her face turned square to the lens in clear three-quarter view with her mouth fully visible, her delight showing plainly in her eyes, raised brows and lifted cheeks rather than in her mouth, which stays free to work so her jaw and lips open and close distinctly on each syllable instead of settling into a fixed open smile or a laugh, and her hands staying down at her sides while she speaks, and calls in a bright, clear young female voice, <d>[English] Sofia!</d> <Subject 3> (S2), her face turned square to the lens in clear three-quarter view with her mouth fully visible, her delight showing plainly in her eyes, raised brows and lifted cheeks rather than in her mouth, which stays free to work so her jaw and lips open and close distinctly on each syllable instead of settling into a fixed open smile or a laugh, and her hands staying down at her sides while she speaks, answers immediately in a warm, delighted young female voice with an easy conversational pace, <d>[English] Up high, come on!</d> Only once her line is finished does <Subject 3> break into a grin and swing her right arm up above her head. Around the four-and-a-half-second mark <Subject 1> swings her right hand up to meet it and the two palms clap together high above their heads, both women still walking forward without breaking step. <Subject 3> laughs, spins once on her heel to the right and drops back out of frame past the right edge, leaving <Subject 1> alone in the centre again. She shakes her hand out, still smiling, drops her arm to her side and settles back into the same even stride. In the final second she is walking straight at the lens exactly as before, the framing unchanged, the shot ending mid-stride.

overall_soundscape:
The open-air street ambience carries straight on from the preceding segment without interruption: traffic on the avenue, the low rumble and warning bell of a streetcar on the rails, wind between the towers and the murmur of passing pedestrians. Two sets of footsteps join for several seconds when the second woman arrives, a sharp palm clap sounds as their hands meet, and her laugh trails off to the right before a single set of even footsteps continues alone.
