1. SCENE CONTEXT: EXACTLY 1 DRAGON — NO DUPLICATES.A 30-second, six-shot dark-fantasy action sequence. A colossal dragon roars, launches from a mountain pinnacle, accelerates toward a burning coastal city, dives between its towers and performs a devastating aerial fire attack. Epic scale, very fast pacing, real-time motion. 2. ACTIVE REFERENCES: controls the burning coastal city, Gothic architecture, harbour, mountain horizon, existing fires, smoke columns, storm clouds and lightning. Controls the dragon’s identity, black-grey scales, red-brown wing membranes, horns, dorsal spines, four legs, two wings, long tail and opening rocky pinnacle. 3. LOCATION MAP: The pinnacle overlooks the coastal city. The harbour lies screen-left, the central castle lies ahead, and the densest burning district lies centre-right. Direction of travel always runs from the mountain toward the city centre. Cameras remain behind, below or on the dragon’s left side without reversing the travel axis. 4. FIRST FRAME AND SPATIAL BLOCKING: The dragon is already crouched on the pinnacle, wings spread, hind legs compressed and head aimed toward the city. Its jaws open for one roar. Fires flicker below; connected smoke columns bend with the wind and the entire storm ceiling visibly moves. 5. FORMAT MODE: Six shots with hard cuts: SHOT 1 — 0.0–4.0s: roar and launch.SHOT 2 — 4.0–9.0s: high-speed pursuit toward the harbour.SHOT 3 — 9.0–13.5s: low flight across the water toward the city.SHOT 4 — 13.5–19.0s: first fire attack between towers.SHOT 5 — 19.0–25.0s: banking pursuit and sweeping fire attack.SHOT 6 — 25.0–30.0s: dragon climbs above the burning city. Cuts are motivated by wing wipes, smoke wipes and close architectural passes. No fades or dissolves. 6. OPTICS SHOT: 1: 24mm, 74° horizontal FOV, low-angle environmental wide.SHOT 2: 18mm, 90° FOV, rear pursuit perspective.SHOT 3: 24mm, 74° FOV, low water-level chase.SHOT 4: 28mm, 65° FOV, roof-height tracking.SHOT 5: 24mm, 74° FOV, close side-rear pursuit.SHOT 6: 18mm, 90° FOV, monumental aerial wide.Moderate-deep focus. Strong natural motion blur on wing tips, water, smoke, embers and nearby buildings. 7. CAMERA: All cameras have obvious physical handheld instability.SHOT 1 rapidly tilts upward as the dragon launches; wing pressure violently jolts the operator.SHOT 2 follows 12 metres behind the tail with intense wind buffeting and rapid vertical vibration.SHOT 3 races just above the water behind the dragon; waves and burning boats whip past the frame edges.SHOT 4 tracks through the street canyon at roof height.SHOT 5 follows the dragon through a hard bank, nearly losing framing as towers pass dangerously close.SHOT 6 pursues upward, then settles into a wide view of the devastated city.No smooth floating or mechanically perfect movement. 8. ACTION TIMING: 0.0–0.8s: The dragon releases one thunderous roar, neck extended and eyes fixed on the city.0.8–2.0s: Hind legs drive into the pinnacle; claws fracture the rock.2.0–4.0s: The dragon launches and performs two powerful wing strokes. Dust and stone explode backward.4.0–6.5s: Hard cut behind the dragon already accelerating at high speed.6.5–9.0s: It folds its legs beneath its body and dives toward the harbour. Smoke streams across its wings.9.0–11.5s: The dragon skims rapidly above rough water. Wing tips nearly touch the waves.11.5–13.5s: It passes burning ships and climbs over the sea wall. A tower wipes across the lens.13.5–15.0s: Hard cut inside the city. The dragon bursts through smoke between Gothic towers.15.0–19.0s: It releases one continuous orange-white fire jet, sweeping across the left row of rooftops while maintaining full speed.19.0–21.5s: The dragon snaps into a hard right bank around the central tower; the tail swings with delayed inertia.21.5–25.0s: Its connected fire stream sweeps across the avenue and strikes the right-side tower. Burning masonry and embers fall behind it.25.0–27.0s: The dragon stops breathing fire, beats its wings powerfully and climbs above the rooftops.27.0–30.0s: It ascends into the storm light and glides over the burning city. The camera widens to reveal spreading flames, smoke columns and the harbour below. 9. PHYSICS: The dragon has immense believable mass despite its speed. Wing strokes originate in the shoulders; membranes stretch under aerodynamic load. The torso, legs and tail react with delayed inertia. Wing wakes tear openings through smoke, disturb water and buffet nearby fires. Fire emerges only from the open mouth as a pressure-driven stream with a white-hot core, orange turbulent edges and visible heat distortion. Buildings ignite progressively at visible impact points. Debris follows gravity and the dragon’s wake. 10. LIGHTING: Cold storm daylight enters from upper-left. Existing fires provide orange underlight beneath the dragon. The fire stream becomes a moving motivated key light, casting travelling highlights over scales, towers and smoke. Sunbeams break through the clouds during the final climb. Preserve detail in the flame core and keep the dragon’s silhouette readable. 11. AUDIO: No dialogue. Synchronized dragon roar, claw scraping, rock fracture, leather-wing thunder, violent wind, wave impacts, burning ships, collapsing masonry, ember hiss and pressurised fire blasts. Epic original score: rapid war drums, low brass ostinato and urgent strings begin immediately. Wordless low choir enters at launch. Percussion accelerates during the chase. Full orchestra strikes with each fire attack, then expands into a dark triumphant finale during the ascent. Roar, wings and fire remain louder than the music. 12. CHARACTER ACTING: The dragon acts with focused predatory intent. Its eyes remain locked on its flight path and successive building targets. During acceleration, its head lowers and shoulders drive aggressively. Inside the city, the neck deliberately guides the fire stream while the tail controls each bank. In the final shot, its chest opens and posture changes from attacking aggression to airborne dominance. 13. STYLE: Grand apocalyptic dark-fantasy cinema, aggressive pursuit photography, monumental scale and battlefield energy. Charcoal and storm blue occupy 60% of the palette, smoke-brown stone 30%, and fire orange 10%. Weathered 35mm film texture with old-photograph softness, organic grain and no digital sharpening. 14. QUALITY: Consistent dragon identity and anatomy through every cut: one head, two wings, four legs and one tail. Stable city architecture, coherent wing cycles, attached mouth fire, volumetric smoke and physically connected destruction. Natural fast-motion blur without ghost copies, anatomy mutation or detached flames. 15. POSITIVE CONSTRAINTS: Exactly one dragon remains visible throughout the sequence. It launches before 2 seconds, reaches the harbour by 9 seconds, enters the city at 13.5 seconds and completes two fast fire-attack passes before climbing away. Every shot preserves the mountain-to-city direction. Strong camera shake communicates extreme speed while the dragon remains readable. City fires continuously emit smoke, clouds visibly travel across the sky, and new destruction appears only where the connected fire stream strikes.

SCENE CONTEXT EXACT 3 UNIQUE HUMAN CHARACTERS ACROSS THE VIDEO: Three people are in a bright, clean, fictional city tourist information center. Maintain consistent color tones throughout. The tourist stands on the left, the interpreter stands in the middle, and the tourism staff member stands on the right. A city map and route diagram are placed on the information desk. Background text and map labels must be blurred and unreadable. No real brands, organization names, logos, or watermarks may appear. ACTION TIMING: 0–3 seconds: Medium shot of all three people. The Spanish female tourist looks at the interpreter in the middle, raises the map in her hand, and speaks in natural, clear, slightly slow Spanish: “¿Dónde está la estación de metro más cercana?” After she finishes speaking, pause for approximately 0.5 seconds. The interpreter turns to the tourism staff member and translates into Chinese: “她想知道最近的地铁站在哪里。” 3–7 seconds: Cut to the interpreter and the tourism staff member. The tourism staff member looks at the map (do not use a close-up of the map) and answers in natural, clear Chinese: “沿这条路直走，步行大约五分钟就能到。” After the staff member finishes speaking, pause for approximately 0.5 seconds. The interpreter confirms understanding and turns toward the tourist. 7–11 seconds: The interpreter translates the staff member's answer into natural, clear, slightly slow Spanish: “La estación de metro está a unos cinco minutos a pie. Siga recto por esta calle.” While speaking, the interpreter points to the route on the map, and the tourist studies it attentively. 11–15 seconds: Return to a medium shot of all three people. After understanding the directions, the Spanish tourist smiles, nods, and says in Spanish: “Muchas gracias.” All three maintain a natural service interaction as the scene ends. AUDIO: - The Spanish tourist speaks only Spanish. - The Chinese tourism staff member speaks only Chinese. - The Chinese interpreter speaks Chinese first, then Spanish. - Each person has a distinct voice. - When one person is speaking, the others remain silent. No interruptions or overlapping dialogue. - All dialogue must have clear vocals, with lip movements synchronized to the corresponding language. - Spanish pronunciation must be natural and standard, without English-accented pronunciation. - Speech should be slightly slow, with natural pauses between sentences. - Retain subtle ambient sounds from a tourist information center. Do not add background music. Ambient sounds must not overpower the dialogue. CAMERA: Begin with a medium shot of all three people to establish their relationships. When the tourist speaks, cut to a two-shot of the tourist and interpreter. When the interpreter relays the question, cut to the interpreter and staff member. During the staff member's response, include a close-up of the map route. When the interpreter translates into Spanish, return to a two-shot of the interpreter and tourist. End with a medium shot of all three people. Maintain consistent character positions, eyelines, and clothing throughout. Do not abruptly replace characters or change their spatial relationships. STYLE: Realistic, natural, professional travel-service documentary style. Bright, clean lighting, natural facial expressions, and restrained movements. The scene should resemble an authentic interaction at an airport or city tourist information center.

1. SCENE CONTEXT EXACT 1 HUMAN CHARACTER — NO DUPLICATES. A woman enthusiastically presents the black Kling cropped puffer jacket she is wearing inside a minimalist fashion showroom. She maintains warm, confident eye contact with the camera while demonstrating the collar, chest logo, quilted construction, cropped silhouette, and pockets. One continuous 15-second vertical fashion shot.2. ACTIVE REFERENCES@Image1 controls the woman’s exact identity, straight brown hair, blue eyes, small earrings, black Kling cropped puffer jacket, high collar, silver zipper, white chest logo, quilted panels, elastic cuffs, side pockets, loose blue jeans, black belt, showroom racks, window, and vertical composition. Preserve every detail exactly. 3. LOCATION MAP: The woman remains centered between two clothing racks. The left rack stays behind frame-left, the second rack remains in the rear-right, and the large window stays on frame-right. The camera remains directly in front of her and moves only slightly toward her left side. 4. FIRST FRAME AND SPATIAL BLOCKING: Match the reference composition. She stands in a relaxed three-quarter position with both arms resting naturally beside her body. The complete jacket, waistline, belt, and upper jeans remain visible. Her head turns toward the camera and her eyes lock naturally onto the lens. 5. FORMAT MODE: One uninterrupted 15-second vertical 9:16 shot. No cuts, fades, dissolves, speed ramps, wardrobe transformations, location changes, or duplicated poses. 6. OPTICS: 50mm equivalent lens with a 40° horizontal field of view. Medium fashion framing keeps her eyes, facial expression, collar, logo, zipper, sleeves, hem, pockets, and waistline readable. Moderate depth of field softly separates her from the clothing racks. 7. CAMERA: A human operator stands approximately two and a half meters away at chest height and performs one slow handheld clockwise arc of less than one meter. Breathing drift, small footsteps, slight roll, and delayed reframing remain visible. The camera never becomes mechanically stabilized or crops out the jacket hem. 8. ACTION TIMING 0.0–2.0s: She finds the lens, takes a light anticipatory breath, and forms a genuine welcoming smile.2.0–5.5s: While beginning her sentence, she touches the structured collar and follows the zipper downward with her fingertips, keeping her eyes on the lens.5.5–8.5s: Her voice becomes more animated as her hand pauses beside the white Kling logo and her free hand opens in a small expressive gesture.8.5–11.5s: She turns into a three-quarter side profile, slips both hands into the pockets, and looks back toward the lens with a confident smile.11.5–15.0s: She faces forward again, relaxes her shoulders, and finishes the presentation with bright eyes and a warm, satisfied expression. 9. PHYSICS The padded jacket compresses naturally beneath her fingertips and recovers after release. Quilted panels retain consistent volume. Sleeves bend and crease at the elbows, while the cropped hem shifts during her turn and settles under gravity. Hair and earrings respond with small delayed movement. 10. LIGHTING: Soft daylight from the large window on frame-right is the single motivated key source. It creates restrained highlights across her eyes, hair, black fabric, silver zipper, and cheekbones while preserving detail in the quilted panels. Ceiling track lights remain subtle background practicals. 11. AUDIO: Layered showroom ambience: quiet room tone, distant ventilation, soft jacket rustle, zipper contact, jeans movement, and restrained footsteps. In a sincere, emotionally engaged English voice, she says: “I honestly love this Kling jacket—the cropped fit feels so confident, and it goes with everything.” Begin with warm appreciation, emphasize “love” and “confident,” then finish with an audible smile. Her lips, breath, expression, and garment gestures synchronize exactly with the sentence. SFX only, no music, no score, no song, no soundtrack. 12. CHARACTER ACTING: She speaks as someone genuinely excited by how the jacket makes her feel. Her eyes stay connected to the lens with living highlights and irregular natural blinks. Her eyebrows lift slightly on “love,” her cheeks rise on “confident,” and her final smile reaches both eyes. She never looks down at the garment while speaking; her hands locate each feature naturally through touch. INNER, UNSPOKEN: “This feels completely like me.” 13. STYLE: Minimal contemporary fashion content captured by an imperfect human companion. Clearly handheld intimacy, old-photograph softness, organic film grain, restrained contrast, natural fabric texture, gentle window halation, and no digital sharpening. Color balance: 60% black and charcoal, 25% cool white showroom tones, 15% faded blue denim and natural skin. 14. QUALITY The woman’s identity, eye color, hairstyle, earrings, jacket geometry, quilted panels, collar, zipper, cuffs, pockets, jeans, and belt remain consistent. The white Kling wordmark remains correctly spelled, stable, and attached to the same chest position. Eyes, lips, hands, fingers, sleeves, and fabric folds remain anatomically coherent. 15. POSITIVE CONSTRAINTS: Exactly one woman wears exactly one black Kling jacket throughout the shot. She maintains direct lens connection while speaking and looks back toward the lens during the side pose. She speaks exactly one emotional English passage and performs one continuous garment presentation. The jacket remains fully zipped and its logo stays visible during front-facing moments. Add no second person, clothing change, subtitle, price, promotional overlay, mirror reflection, music, or runway movement. A flat, emotionless delivery, wandering eyeline, malformed wordmark, changing jacket length, extra limb, or fabric passing through her body equals a failed shot.
One video, two photos, a whole new take
Camera movement reference: the input video contributes only its camera moves and shot pacing, one photo supplies the new subject, another supplies the setting. Kling 4.0 transplants the cinematography onto a completely different scene.
The prompt
Use @Video1 as the reference for camera movements and shot pacing. Replace the Element with the car from @Image1 and the background with @Image2.
What Is Kling 4.0?
Kling 4.0 is Kuaishou's next-generation audio-visual video model — the engine behind Kling AI, announced on September 28, 2026 and fully released on October 15. A single generation now runs anywhere from 3 to 30 seconds in one-second steps, at 720p, 1080p or 4K, in four aspect ratios plus an Auto mode that follows your first frame. Sound is native: two-channel stereo with improved lip-sync, and spoken dialogue in nine languages — Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French and Hindi — with authentic dialects and accents from Cantonese and Sichuanese to British and Indian English.
Control goes much deeper than a text box. Keyframes pin up to ten stills along the timeline; Omni Reference composes a scene from up to 15 assets — ten images, five videos totaling 30 seconds, seven elements and three voice profiles; a camera-movement reference transplants one video's cinematography onto a new subject, as the anatomy above shows; and a video-editing mode reworks up to five clips totaling 30 seconds. Prompts can run to 8,000 tokens, and a Flash tier trades keyframes and resolution ceilings for speed: 720p clips up to 20 seconds.
Kling 4.0 arrives on Molyin at launch, inside the same AI video generator as every other model we host — one prompt box, one credit balance. Until then, every sample on this page remixes onto the models already live; the pricing page has the numbers.
