SCENE CONTEXT
SROK episode 4, scene 5, OPTICS REVISION V2. Same story and continuous-take timing, with a narrower perspective and tighter subject framing. Fifteen seconds, ONE CONTINUOUS SHOT, ZERO CUTS. The father is already crouching in an embrace with preschool Misha. He already wears his blue jacket; the single travel bag beside him is zipped shut, rabbit inside. Dressing and packing happened between scenes.
THE DEVICE — RISE WITH THE FATHER, REMAIN WITH THE FAMILY. A modest camera rise accompanies him standing; the camera then stays inside with mother and son while he leaves.
Misha wants more time with Dad and a simple answer about tomorrow. Father receives the embrace without making a promise. Mother answers honestly and offers physical reassurance. Restrained ordinary behaviour, active attention, no tears or invented farewell words.

ACTIVE REFERENCES
@image1 — FATHER IN JACKET. Preserve his tall lean build, sandy swept forelock, grey-blue eyes, long nose, freckles and light stubble. Open navy zip jacket over grey crewneck sweater, dark jeans, white sneakers, wedding ring. Use identity and clothes, not the fixed smile, card pose, grey field or panels.
@image2 — MISHA. Same small preschool boy, tousled sandy-brown felted hair, brown eyes, freckles, pink nose and round cheeks. Butter-yellow long-sleeve pajamas, grey-blue trousers, white socks. Keep child-sized body and hands.
@image3 — MOTHER. Same narrow oval face, hooded hazel-olive eyes, freckles and left-cheek beauty mark, brown hair in charcoal claw clip, temple strands and gold studs. Camel ribbed top and matching wide trousers, white socks, FULL 28-WEEK PREGNANCY BELLY.
@image4 — HALL. Preserve pale timber floor, sage runner, left interior doorway/shoe bench, right pale-wood console, warm pendant and cream front door. From inside: handle LEFT, hinges RIGHT. One starting-state change: the door is already open inward toward the right wall.
@image5 — ONE BAG. Use only the CLOSED UPPER VIEW: slate-blue canvas, two charcoal handles, brass zipper fully shut. Rabbit and clothes are packed inside and invisible; the lower open view never appears.
All figures share the established tactile stylized 3D finish: flocked matte skin, felted hair, knit, woven canvas, wood and dimensional light falloff. Reference sheets supply designs only, never panels or studio backgrounds.

LOCATION MAP
Camera stays inside, slightly left of the hall centreline, looking toward the front door. Mother stands beside the left interior doorway; Misha stands a small step to her right on the runner. Father crouches just beyond him, centre-right, three-quarter to camera so both embracing faces read. Bag is beside father's anatomical LEFT foot, clear of the boy.
Door starts about 60 degrees open, hinged at screen-right and held toward the right wall. Mother and child stay LEFT of its swing. Father crosses the clear central doorway with bag in LEFT hand; RIGHT hand controls the door.
Crop the mirror's reflective surface out of the composition. Door hardware, console and furniture stay fixed.

FIRST FRAME
A TIGHT MEDIUM of father and Misha in their embrace, composed around their heads, shoulders and the child's torso. Camera at about 85 centimetres, standing farther away with a 29-degree field of view. The mother is only partly visible at the left edge initially. The father's feet, whole bag, full door and ceiling are NOT simultaneous framing requirements: they remain in their established positions outside the crop or at its edges. No large empty room around the figures. Child and adult faces retain natural proportions, without enlargement from proximity to the lens.

FORMAT MODE
Native vertical 9:16, one full-frame image, no split screen, captions or borders.

OPTICS
Fixed FOV 29 degrees, approximately f/4, with the camera farther from the family, roughly 3.0-3.6 metres from the initial embrace. Set distance to obtain a tight medium grouping, never move the lens close to the nearest face to fill the frame. Foreground hands and heads have restrained size; background perspective feels calmer and the corridor falls softly out of focus.
The opening prioritizes the embrace. The ending prioritizes the mother's face and Misha's face together in a compact two-person medium, the top of frame just above her head and the lower boundary around his upper thighs. Full feet, complete bag, entire door leaf, console and mirror may stay outside the crop. Keep continuity offscreen instead of widening to prove every object exists. There is no full-room establishing shot. No zoom, lens swap or wide-angle distortion.

CAMERA
0.0-3.0: hold the tight embrace from child height and the farther camera position. Mother may be partly cropped at the side; the faces participating in the hug are the subject.
3.0-5.0: one gentle physical rise of about 30 centimetres, from 85 to 115 centimetres, as father stands. A slight continuous compensating tilt allows his rise, then settles on mother and son. Do not rise to adult eye height, pull back, or widen the lens. The same 29-degree perspective remains throughout.
5.0-15.0: hold a compact mother-and-child composition at the inner end of the hallway. Father moves through the background doorway or the right edge and exits once; his bag pickup may occur partly below the framing, and the door closure can finish at the rear edge. We hear the latch and see father absent, without reframing to demonstrate the entire leaf. Mother's face, Misha's face and the final handhold remain readable. No hidden cut, zoom, orbit or further camera move.

ACTION SEQUENCE
0.0–1.6: the embrace is already happening. Misha holds both arms around Dad's shoulders. Father supports his upper back without lifting him. Mother waits nearby.
1.6–3.0: Misha slowly loosens his arms. Father releases in response, briefly settles his hands at the boy's upper arms, then withdraws. Their hands separate before he stands.
3.0–5.0: father rises naturally; camera makes its single small rise. Misha stays on both feet and follows him with his eyes.
5.0–6.0: father bends enough to grip BOTH short bag handles together in his LEFT hand and lifts the CLOSED bag once. It hangs with weight at his left thigh.
6.0–9.0: two ordinary steps through the already-open doorway. Bag stays left, right hand free. While crossing the threshold he takes the door's free latch edge from the landing side with his RIGHT hand. His body and bag clear the threshold before the leaf swings across it. This is his only exit.
9.0–10.0: from outside he gently pulls the SAME door shut. Right hand withdraws behind the leaf before the gap closes; the fixed right-side hinges remain unchanged. Soft latch. Father and bag stay outside and out of view. Misha watches.
10.0–10.2: Misha turns his head slightly up toward mother, showing his mouth in readable three-quarter profile.
10.2–12.0: MISHA says quietly and simply in Russian: "Папа завтра придёт?" Natural preschool voice, asking a real question. Mother listens with closed mouth.
12.0–12.3: natural pause. Mother looks down toward him; her mouth stays visible.
12.3–13.5: MOTHER says quietly and evenly in Russian: "Не знаю." Plain honest uncertainty. Misha listens with closed mouth.
13.5–15.0: mother's LEFT hand takes Misha's RIGHT hand. They begin a small turn toward the interior doorway at frame-left. Their continued walk happens after this clip. Hold joined hands and readable faces; no further speech.

ANIMATION STYLE
Restrained tactile stylized 3D character animation on twos within a 24 fps output, with a smoothly weighted physical camera rise. Natural child-sized balance, measured release of the embrace, believable standing and two walking steps. Small cloth settling follows body motion. Quiet listening stays alive through breath and an occasional blink; no idle swaying or broad pantomime.

PHYSICS
Exactly three people initially, each with two arms, two hands and ten fingers. Misha stays on the floor during the hug. One closed bag, lifted once and carried continuously in father's LEFT hand; RIGHT hand closes the door. Father and bag clear the threshold before its single right-hinged closing swing. Mother and son remain clear of the leaf. Rabbit stays invisible inside the bag. At the end exactly two people remain visible, mother's LEFT hand holding child's RIGHT. All contacts are physical, without intersecting bodies, door or fabric.

LIGHTING
Match the hallway's ordinary warm evening light: soft pendant around 3000K, gentle warm spill from the left interior room and weaker neutral landing light through the open doorway. Closing the door removes only that small landing contribution. Mother's face, the boy's mouth and the pregnancy remain readable under the existing hall light; no dramatic exposure change. Soft dimensional face modelling, grounded contact shadows and matte tactile surfaces.

AUDIO
NO BACKGROUND MUSIC, NO SCORE, NO MUSICAL STING.
Exactly TWO non-overlapping Russian passages, once each: MISHA, "Папа завтра придёт?"; then MOTHER, "Не знаю." Accurate visible lip-sync only on the current speaker. Father never speaks. Otherwise only quiet room tone, soft jacket/pajama rustle, two sneaker steps, canvas handles taking weight and a gentle door latch. No invented goodbye, crying, gasp, ringtone or dramatic impact.

QUALITY
Stable faces, small-child scale and full maternal pregnancy throughout the continuous move. Preserve navy jacket, yellow-grey pajamas, camel knit and closed slate-blue bag. Legible mouth shapes during both lines, coherent hand release and handholding, natural door geometry. Fine natural film grain, tactile matte materials. No text, logos, numbers, subtitles, UI or reflected duplicate people.

TECHNICAL PARAMETERS
Seedance 2.5, direct BytePlus/ByteDance, 480p, vertical 9:16, 24 fps output. Exactly 15.0 seconds, fixed 29-degree perspective, ONE continuous shot and ZERO cuts. One small camera rise during 3.0–5.0 seconds, then a settled camera. Real time, no slow motion or speed ramp. Generate synchronized Russian dialogue and quiet diegetic sound.
