Cinematic scene

Blue Hour Chemistry Jessica: Face locked from uploaded reference image. Sleek straight black hair, elegant black satin mini slip dress with tasteful thigh-high slit, black strappy heels, gold jewelry, deep red lips. Marco: Handsome Western man with deep blue eyes, dark swept-back hair, light stubble, athletic build, fitted navy shirt, tailored trousers. CUT 1 (0:00–0:04) · Luxury Penthouse Low-angle tracking shot follows Jessica walking confidently across the penthouse. The camera tilts up as she reaches the floor-to-ceiling windows overlooking the glowing skyline. She slowly turns over her shoulder. Marco enters and instantly stops, captivated. Slow Motion (40%) Close-up of Jessica's face as she locks eyes with Marco, gives a subtle smile, gently bites her lower lip for a brief moment, then turns and walks away with quiet confidence. CUT 2 (0:04–0:08) · Penthouse Lounge Jessica walks toward the suite corridor. Marco follows beside her. They exchange lingering eye contact. Their shoulders lightly brush. Their hands naturally meet before their fingers slowly intertwine. The camera smoothly circles around them. CUT 3 (0:08–0:12) · Outside the Suite Marco gently tucks a strand of Jessica's hair behind her ear. She steps closer. They hold eye contact. Slow Motion (40%) Marco leans in until only inches separate them. Jessica smiles softly. Marco (whispering): "Come with me." Jessica smiles, takes his hand, and nods. CUT 4 (0:12–0:15) · Luxury Bedroom Marco opens the suite door and gently lifts Jessica into his arms. She smiles, wrapping one arm around his shoulder. He carries her into the softly lit bedroom and carefully places her on the edge of the bed. They share one final lingering smile as the camera slowly pushes in. Fade to black.

Cinematic scene

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 pedestrians, no other rooftop figures, no extras. Only the runner, the enforcer, and one drone are ever visible. THE NEON FLARE — CRITICAL: neon signage below strobes the rooftops in hard magenta and cyan flashes throughout. The stepped quality of any lit moment comes entirely from this signage-flicker, never from broken footage — camera motion stays smooth throughout. Falling rain streaks diagonally, screen-right to left. Subject Lock — the runner: lean wiry build, shaved head, sharp cheekbones, rain-slicked dark skin, clean face, no visible tattoos. Matte black tactical jacket over a compression base layer, fingerless gloves, worn parkour shoes. Carries nothing but bare hands. Sprints rooftop to rooftop toward the city's edge, never breaking stride mid-leap. Subject Lock — the enforcer: bulky armored build, a featureless matte-grey full-face helmet with a single red visor slit, reinforced shoulder plating, heavy boots. Carries a stun baton crackling with blue arcs. Pursues in a steady mechanical stride, never sprinting, always closing distance. World Plate: a dense cyberpunk rooftop skyline at night in rain — sheet-metal water tanks, tangled cable runs, a gap between towers spanned by a rusted service bridge, neon signage glowing far below through the haze. No other structures present. THE ATMOSPHERE — CRITICAL, depth only: heavy rain-haze at high density — runner sharp near, enforcer softened mid-distance, distant towers near-erased far. Reads as thickened wet air only, never a fog-machine look. SHOT 1 — 0.0-5.0s. THE SPRINT. Low camera at rooftop level, cant 15°, tracking the runner forward. Runner sprints across gravel rooftop, enforcer's baton-glow closing from behind. Runner screen-left sprinting, enforcer screen-right pursuing. Diegetic sound. SHOT 2 — 5.0-10.0s. THE STRIKE. Camera orbits tight at chest height, cant swinging 15-35°, never square. Baton arcs crackle past the runner's shoulder, runner ducks and shoulder-checks the enforcer's plating. Both centered, rain scattering. Diegetic sound. SHOT 3 — 10.0-15.0s. THE WATCHER. Cut to a small surveillance drone hovering between towers, its red scan-light sweeping as wind gusts rock it sideways. It corrects and holds position. Drone centered against the neon-lit haze. Diegetic sound. SHOT 4 — 15.0-20.0s. THE COLLAPSE. Low static camera at the service bridge, whip-panning up as a rusted support strut gives way. The bridge section buckles and drops; the runner leaps clear across the widening gap. Bridge diagonal across frame, runner emerging low center. Diegetic sound. SHOT 5 — 20.0-25.0s. THE SURGE. Camera drops to rooftop height, rockets forward through a rain corridor lit by a fresh neon flare. Runner sprints hard, jacket soaked, closing the last stretch toward the city's edge. Runner screen-left driving right. Diegetic sound. SHOT 6 — 25.0-30.0s. THE AFTERMATH. Camera pulls back to a wide static rooftop frame, rain falling straight now, wind dying. The runner stands alone at the tower's edge, chest heaving, as the enforcer's red visor dims below the ledge and it stops advancing. Runner small and centered, collapsed bridge dark behind. Diegetic sound. Cross-Frame Rules: runner's jacket and gloves never change. Enforcer's visor-glow never fully fades until Shot 6. Only runner, enforcer, and drone ever visible. Rain direction stays constant. Bridge keeps the same collapsed shape wherever it appears. Neon-flare applies only inside Shots 1, 2, and 5. No score enters at any point. Last Frame: the runner stands alone at the rooftop's edge, rain falling straight down, the enforcer's dimmed red visor faint at the frame's edge below, the collapsed bridge looming behind under neon haze. No on-screen text, no logo, no watermark. Sound Bed: diegetic only — heavy rain, the baton's electric crackle, boots pounding gravel, metal groaning and snapping, a drone's faint rotor whine. No score, no subtitles. Camera & Capture Realism: ~32mm/68° FOV, vintage 2x anamorphic with oval bokeh and streak flares off the neon, 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 gimbal-glide. No CGI look, no AI smoothness, no video-game HUD, no motion smoothing.

Cinematic scene

Character: A beautiful young woman with voluminous curly hair, warm brown skin tone, minimal natural makeup, wearing a soft solid pink hoodie. Expressive, friendly face, animated natural hand gestures like a content creator recording a casual video for her audience. She speaks at a relaxed, natural conversational pace, not rushed, with brief natural pauses between thoughts, like talking to a friend rather than reading a script. Style: Realistic cinematic UGC-style content creator video, shot like a home podcast studio setup, warm and cozy mood, shallow depth of field, soft pink and purple neon bokeh lighting in the background, warm key light on her face and soft natural shadows, slightly grainy handheld realism, not overly polished or corporate. Visual: She sits at a light wooden desk directly facing camera. In front of her on the desk stands a large silver studio condenser microphone mounted on a metal scissor arm stand, angled toward her mouth. To her side, a light purple/lavender mechanical keyboard sits on a dark desk mat. Behind her is a tall black shelving unit filled with collectible plush toys and vinyl figures, lit from below with warm orange and pink LED strip lighting. A glowing neon sign shaped like a small cloud hangs on the wall behind her to one side. The background is softly out of focus with warm pink, purple, and orange ambient light glowing at the edges of frame. A tall pink glass bottle sits off to the side of the desk, partly out of focus, sealed with a green foil cap, with a circular pink label reading "OH ME OH MY NIMOSA" decorated with bright red strawberry illustrations and the word "STRAWBERRY" near its base. She starts mid-conversation, already animated, mid-rant about a small daily annoyance, speaking casually and unhurried. She pauses mid-sentence, glances down and to the side as if just noticing something on her desk, reaches over and picks up the pink bottle, brings it into full focus in front of her, turns it slightly so the strawberry label faces camera clearly. She grips the green foil cap with her fingers and twists it counter-clockwise, visibly loosening and removing it, setting it down beside the bottle. Only once the cap is fully off does she raise the open bottle to her lips, tilt her head back slightly, and take a sip. She lowers the bottle, swallows, and reacts with a genuine satisfied smile before continuing to talk warmly, holding the bottle up as she speaks. Camera: Static medium shot, eye level, framed from mid-chest up, subtle natural handheld sway, shallow focus that shifts from her face to sharply on the bottle once she lifts it into frame. Dialogue (for lip sync / AI voiceover): "Why does every app need to notify me about nothing? My phone was buzzing the entire— wait. Oh my god, I almost forgot, check this out. This is the Oh Me Oh My Nimosa, strawberry flavor. This is my go-to drink every time. You guys need to try this." Pacing: Slow, unhurried delivery throughout the entire clip, no rushed speech, natural breathing pauses between sentences.

Cinematic scene

A cinematic desert journey at golden sunset, a mysterious woman wrapped in flowing translucent fabric stands among endless sand dunes, her veil dancing gracefully in the wind. The camera slowly pushes in as warm sunlight creates dreamy lens flares and soft shadows. Cut to an ultra-detailed close-up of a camel walking through the desert, with a caravan crossing distant dunes. The scene transitions into a breathtaking twilight landscape with a glowing crescent moon above rolling sands. Atmospheric dust particles, golden-hour lighting, rich amber tones, shallow depth of field, cinematic composition, ultra-realistic textures, emotional storytelling, smooth camera movement, volumetric light, 4K film quality, epic desert fantasy aesthetic.

Cinematic scene

Style:Ultra-realistic luxury travel vlog, indistinguishable from footage shot on a Sony FX3 with a 24mm cinematic lens. Natural handheld camera movement with subtle stabilization, authentic lighting, realistic skin texture, true-to-life colors, cinematic HDR, and shallow depth of field. The video should feel like a premium travel influencer's Instagram Reel, not AI-generated.

Smooth tracking shots alternate between inside the car and low-angle exterior shots as palm trees and modern skyscrapers pass by. 5.5–8.5s | Rooftop Infinity Pool She relaxes in a rooftop infinity pool overlooking the Burj Khalifa. She adjusts her sunglasses, smiles naturally, and trails her fingertips through the water.

The camera circles around her as the skyline glows in warm evening light. 11.0–14.0s | Sunset Finale She stands at the bow of the yacht, watching the sun set behind the Dubai skyline.

A higher rate is not a quality guarantee / Seedance 2.0 Fast

A higher rate is not a quality guarantee / Seedance 2.0 Fast — Every standard rate is above the corresponding Fast rate, but a higher price does not guarantee better image quality, instruction following, stability, or success rate.

Capabilities

Three mutually exclusive input scenes

Three mutually exclusive input scenes — Text accepts no media; frames requires a first frame and allows a last frame; reference requires a prompt and at least one image, video, or audio reference. Reference media cannot be sent with endpoint-frame fields.

Eight controls and dynamic credit calculation

Eight controls and dynamic credit calculation — Kyeo AI sends resolution, seven ratios including `adaptive`, 4–15-second duration, generated audio, returned last frame, web search, and an NSFW check, then selects one of two rate formulas. Kyeo currently exposes 480p and 720p.

Count, format, size, and duration rules for media

Count, format, size, and duration rules for media — Kyeo AI allows JPG/JPEG/PNG/WebP/GIF/BMP/TIFF images up to 30 MB, videos up to 50 MB, and audio up to 15 MB. Reference mode accepts 9 images, 3 videos, and 3 audio files, with separate 15-second aggregate limits for video and audio. Images must be 300–6000 pixels on each side with a 0.4–2.5 ratio; reference videos must be 300–6000 pixels on each side, have 409600–927408 pixels total, and run at 24–60 fps. Upload metadata is verified again before generation.

Use cases

A text-only shot sample

Submit only a prompt in the text scene, keep ratio, resolution, and duration fixed, and review the shot, movement, audio, and any rendered text against the brief.

A first-frame or endpoint-frame transition

The frames scene requires a first frame and can add a last frame. It anchors endpoints, but intermediate people, objects, text, and motion still require frame-by-frame review.

A matched multimodal comparison

Assign a role to each image, video, or audio file in reference mode, then run the same input through Fast. Reference media does not guarantee consistent results.

Prompt tips

Write observable camera and action requirements

Describe framing, camera movement, subject action, environmental change, dialogue, and sound in sequence. Replace labels such as 'cinematic' or 'perfectly stable' with reviewable conditions.

Assign a specific role to every reference

State which image supplies subject or composition, which clip supplies motion or camera behavior, and which audio file supplies timing.

Change one variable at a time

Complete a 480p, 4-second request first, then change resolution, duration, media, or model version separately. Recalculate credits on every request so the source of a difference remains visible.

Why choose it

Capabilities — Three explicit scene modes cover text, first or first-and-last frames, and multimodal references.
Resolution — Kyeo AI offers 480p/720p and every integer duration from 4 through 15 seconds.
Upload limit — The page checks reference counts and the total duration of video and audio inputs.
Credit cost — The current media combination can be priced before task creation.

What to know first

Seedance 2.0 Fast / NSFW check — The NSFW check defaults off; whether enabled or not, it does not replace manual content, rights, and publication review.
Seedance 2.0 Fast / Runtime — Compare matched requests and record queueing, runtime, failures, and retries instead of treating the name as a guarantee.
Seedance 2.0 Fast / Category — No. Review people, voices, text, products, trademarks, copyright, likeness rights, and advertising claims. Uploading image, video, or audio references—or enabling web search—does not grant rights or publication clearance.
