Cinematic scene

Create a 30-second, 1080p ultra-realistic home video of the same young adult woman spending an unplanned afternoon in a quiet coastal neighborhood. Character: Natural expressive face, warm brown eyes, realistic skin, long dark-brown messy ponytail. Ivory oversized linen shirt, muted-blue camisole, sand-colored trousers, white sneakers, brown crossbody bag, silver hoops and watch. Maintain exact identity, outfit, hairstyle, proportions, and accessories throughout. Setting: Authentic seaside residential streets with weathered homes, narrow lanes, plants, bicycles, laundry, ocean glimpses, and a waterfront path. No brands, landmarks, advertisements, or staged crowds. Camera: Older handheld consumer camera operated by a friend. Imperfect framing, natural shake, autofocus hunting, exposure shifts, motion blur, digital noise, and compression. No gimbal, drone, slow motion, or polished commercial look. Sequence: 0–5s: She exits carrying a paper bag, checks her phone, and laughs when wind catches her shirt. 5–10s: She notices colorful kites, stops to watch, and the camera briefly loses focus. 10–15s: A child's kite catches on a fence; she gently frees it and returns it, creating a natural spontaneous moment. 15–20s: She walks toward the sea and quietly watches the water as wind moves her hair and clothing. 20–25s: Ocean spray surprises her; she laughs, looks toward the camera, and wipes water from her face. 25–30s: Warm sunlight breaks through clouds. She smiles subtly at the camera, then walks away beside the ocean. Hard cut to black at 29.5s. Realism: Accurate physics, natural walking, hair, fabric, paper, kite strings, seawater, lighting, shadows, hands, and facial expressions. No distortions, duplicated objects, disappearing props, wardrobe changes, or anatomy errors. Audio: Natural wind, ocean, birds, footsteps, bicycles, neighborhood ambience, paper rustling, and genuine laughter. No music, narration, subtitles, captions, logos, or watermarks. Final feel: A beautiful but ordinary moment accidentally captured by a friend—intimate, imperfect, spontaneous, and genuinely real.

Cinematic scene

SEEDANCE 2.5 | 30s | 16:9 | ULTRA-PHOTOREALISTIC SMARTPHONE VLOG A genuine personal smartphone travel vlog of a Korean woman in her early 20s experiencing Istanbul for the first time. Spontaneous, natural and slightly imperfect — never a tourism commercial. CHARACTER: Same Korean woman throughout. Petite oval face, expressive brown eyes, long black hair with loose strands, realistic fair skin and natural imperfections. Cream ribbed top, dark-brown wide-leg trousers, open beige trench coat, brown crossbody bag, white sneakers, delicate gold jewelry. No identity or wardrobe changes. She speaks only Turkish with a natural Korean accent, slightly imperfect and conversational. No subtitles, captions or translations. CAMERA: Handheld smartphone, 16:9 landscape. Natural arm movement, walking jolts, imperfect framing, autofocus delays, exposure shifts, realistic motion blur and phone-camera texture. No gimbal, drone, cinematic lens effects or commercial grading. STORY 0–4s — HAGIA SOPHIA: Selfie walk through Sultanahmet with Hagia Sophia behind her. She turns the camera toward it, then back to herself and says: “Vay… Ayasofya gerçekten çok güzel.” 4–7s — BLUE MOSQUE: Show the Blue Mosque, square, pigeons and pedestrians. She walks through frame, looking around with quiet curiosity. 7–11s — TOPKAPI: She explores Topkapı Palace courtyards and architecture, briefly showing the Bosphorus. She says: “Burası çok eski… çok güzel.” 11–14s — BREAKFAST: Local café table with simit, cheese, olives, eggs and Turkish tea. She takes a bite of simit and says: “Bu kahvaltı çok güzel!” 14–17s — COFFEE: Close handheld shot of Turkish coffee being prepared and poured. She sips, reacts naturally and says: “Kahve çok güçlü!” She laughs. 17–20s — GRAND BAZAAR: Busy authentic bazaar with lamps, ceramics, textiles and pedestrians. She films while walking and casually moves aside as someone passes. 20–23s — GALATA / İSTİKLAL: Galata Tower, historic streets and red tram. She looks up, turns to camera and says: “İstanbul çok güzel bir şehir.” 23–27s — BOSPHORUS: Golden-hour ferry selfie. Wind moves her hair and trench coat. She turns toward the Bosphorus, ferries, seagulls and bridges, then softly says: “Burası inanılmaz…” 27–30s — NIGHT: Warm Istanbul street lights, taxis, pedestrians and trams behind her. She smiles at the camera and says: “İstanbul, seni çok sevdim. Tekrar geleceğim!” She raises her hand and naturally covers the lens. AUDIO: Authentic Istanbul ambience — traffic, trams, ferries, seagulls, footsteps, vendors, cafés, wind and pedestrians — mixed with a subtle upbeat travel soundtrack. Natural Korean-accented Turkish dialogue. REALISM LOCK: Authentic Istanbul locations, realistic crowds, food, coffee, ferry movement, wind, shadows, reflections, skin, hair and fabric physics. Natural expressions and imperfect camera behavior. NEGATIVE: No face drift, duplicate people, distorted hands, floating objects, fake crowds, plastic skin, beauty filter, exaggerated reactions, impossible architecture, teleporting, subtitles, captions, text, logos, watermark, CGI or tourism-commercial aesthetic.

6 shots, total 30s 0.0-5.0s, 5.0-10.0s, 10.0-15.0s, 15.0-20.0s, 20.0-25.0s, 25.0-30.0s. Hard cuts, no dissolves. Normal speed throughout, no slow motion, no ramping. CAPTURE CADENCE CRITICAL: native 24fps, true 180-degree shutter, real 1/48s exposure every frame. Fluid, continuous motion blur. Never choppy, never juddering. No interpolation, no ghosting, no video look. NO ON-SCREEN TEXT CRITICAL: no text of any kind anywhere in frame. No captions, subtitles, titles, credits, watermarks, logos, timecode, UI overlays. NOBODY ELSE IN FRAME CRITICAL: no monks, villagers, or extras. Only the swordsman, the oni, and one crow are ever visible. THE FIRE CRITICAL: burning temple embers drift and flare through every frame, occasionally flaring bright enough to strobe-light a beat. The stepped quality of any lit moment comes entirely from ember-flare, never from broken footage camera motion stays smooth throughout. Falling ash rakes diagonally, screen-left to right. Subject Lock the swordsman: lean weathered build, closecropped greystreaked hair, hard jaw, sootstreaked skin, clean face, no tattoos. Charcoal hakama and a scorched indigo haori, one steel pauldron, straw sandals. Grips a curved katana two-handed. Advances through the burning temple courtyard toward the oni, stance low and controlled through every strike. Subject Lock the oni: towering horned demon, no visible pores cracked obsidian-red skin glowing along fault lines with molten orange light, tusked jaw, matted black mane. Carries a massive iron kanabo studded with spikes. Advances with heavy ground-shaking steps, never runs. World Plate: a burning temple courtyard at night a shattered stone torii gate, a collapsing pagoda roof shedding tile, a wide gravel yard scattered with broken lanterns, distant burning rooftops beyond the temple wall. No other structures stand whole. THE ATMOSPHERE CRITICAL, depth only: heavy smoke haze at high density swordsman sharp near, oni softened at mid-distance, burning rooftops near-erased far. Thickened smoke-air only, never a fog-machine look. SHOT 1 0.0-5.0s. THE ADVANCE. Low camera at gravel level, cant 15°, tracking the swordsman forward. Swordsman strides through drifting embers, katana raised, oni looming ahead. Swordsman screenleft advancing, oni screen-right filling the yard. Diegetic sound. SHOT 2 5.0-10.0s. THE CLASH. Camera orbits tight at chest height, cant swinging 15-35°, never square. Katana rings off the kanabo in a shower of sparks, swordsman thrown back a step. Both centered, gravel kicking up. Diegetic sound. SHOT 3 10.0-15.0s. THE OMEN. Cut to a crow bursting off the collapsing pagoda roof as tile showers down. It wheels hard away from the falling debris. Crow centered against the burning roofline. Diegetic sound. SHOT 4 15.0-20.0s. THE COLLAPSE. Low static camera in the courtyard, whip-panning up as the pagoda roof gives way. The roof section tears free and crashes into the yard; the swordsman rolls clear through gravel and ash. Roof beam diagonal across frame, swordsman emerging low center. Diegetic sound. SHOT 5 20.0-25.0s. THE SURGE. Camera drops to ground height, rockets forward through a corridor of drifting embers lit by a flare of firelight. Swordsman sprints low, katana trailing sparks, closing on the oni's flank. Swordsman screen-left driving right. Diegetic sound. SHOT 6 25.0-30.0s. THE AFTERMATH. Camera pulls back to a wide static courtyard frame, embers settling, wind dying. The swordsman stands alone, katana lowered, chest heaving, as the oni's glowing fault-lines dim to black and it topples out of frame. Swordsman small and centered, burning pagoda dark behind. Diegetic sound. Cross-Frame Rules: swordsman's haori, pauldron, and sandals never change. Oni's fault-line glow never fully fades until Shot 6. Only swordsman, oni, and crow ever visible. Ash direction stays constant. Pagoda keeps the same silhouette wherever it appears. Ember-flare applies only inside Shots 1, 2, and 5. No score enters at any point. Last Frame: the swordsman stands alone in the courtyard, katana lowered, embers drifting down around him, the oni's dark fallen shape at the frame's edge, the pagoda's broken silhouette burning low behind. No on-screen text, no logo, no watermark. Sound Bed: diegetic only — crackling fire, falling tile, katana ringing off iron, the oni's low guttural roar, gravel crunching underfoot, a crow's sharp cry. No score, no subtitles. Camera & Capture Realism: ~32mm/68° FOV, vintage 2x anamorphic with oval bokeh and streak flares off the firelight, shallow depth of field, color-negative rendition, fine grain. Violent handheld cant swinging 15-45°, punching in and ripping back, every frame mid-move but smooth in its own travel, never locked, never gimbalglide. No CGI look, no AI smoothness, no videogame HUD, no motion smoothing.

Cinematic scene

Cinematic fashion film of a young woman with long dark wavy hair walking through New York City. She wears oversized brown tortoiseshell sunglasses, gold hoop earrings, a cream sherpa fleece jacket with black leather trim and toggle buttons, a black mini skirt, black tights, and chunky black loafers, carrying a small black shoulder bag. Sequence: she exits a glass-door building, crosses a busy intersection with yellow taxis, glances into a café window, walks the sidewalk, buys a cold water bottle from a street cart, drinks it, sits on a green park bench, then walks away. Natural daylight, golden-hour highlights, smooth handheld and tracking shots, close-ups of her face, hair, and outfit details. Aesthetic street-style, 4K, filmic color grade, shallow depth of field.

Decision guide

Still deciding? Start with these key decision points.

When a controlled test makes sense

When you need to validate one specific path in Kyeo's current Fast interface and are willing to use non-critical media to confirm the request, callback, result, and credit charge, start with the smallest sample.

When to compare another model

Compare Lite for a lower local base charge. Sora 2 Pro is now a Legacy workflow and should not be a default delivery baseline.

Minimum verification path

Minimum verification path: Before delivery, verify the selected mode, duration, actual dimensions, audio, URL lifetime and billed credits with a non-sensitive sample.

Prompt tips

Select `generationType` before refining the prompt

Decide whether the brief begins from text, first/last frames, or reference images. A long prompt cannot compensate for choosing the wrong media workflow.

Assign each reference image a clear role

When using one to three reference images, label whether each image provides the subject, styling, or visual style, then check for roles that were mixed up or omitted.

Treat upscaling and extension as separate steps

They are separate actions on a successful task with additional charges. Higher resolution does not guarantee better content, motion, or detail.
