Seedance 2.5 Alin 发射重炮 电影写实提示词

15s, 16:9, realistic sci-fi war short film, no dialogue, cinematic live-action VFX. Use Image 1 as the only reference for Alin: adult woman, exact face, pale blonde straight long hair with blunt bangs, white pleated camisole top, blue jeans, brown engraved metal-buckle belt, dark brown knee-high boots, original body proportions and clothing structure unchanged. Add light battlefield dust, sweat sheen, fabric scuffs. Do not inherit short black hair or black leather armor. Use Image 2 only as zombie reference for the nearest infected: mix of a tall thin hoodie male, short heavy worker male, tall office woman, middle-aged apron woman, hunched old man, all scattered naturally into the horde. No copied faces, no repeated poses, no uniform marching. Different heights, outfits, gaits, densities. Some drag feet, some stumble-run, some detour around blocked bodies. Far layers fade into sand and dust. Use Image 3 only as the heavy cannon reference for closed form and fully deployed final form. Keep the black iron boxy main body, side circular mechanical cover, top optical unit, bottom rectangular support module, sliding rails, multi-barrel cluster, fixed muzzle layout with 8 large outer barrels and 4 smaller central holes. Mid transformation must use real hinges and telescoping rails. No floating parts, no magical morphing, no skipped steps. Scene: Alin stands alone in a dusty wasteland industrial ruin. Broken industrial towers surround the battlefield. The central tower is the firing-axis anchor. A burned, deformed abandoned sedan sits to the right of the attack axis in front of the central tower; this same car must be launched near the end and fly toward camera. Alin holds the heavy cannon with both hands: right hand on rear control grip, left hand supporting the lower front fixed body, hand safely away from moving rails. Do not change hand placement. 0.0-1.5s Large rear three-quarter wide shot. Alin stands in the left lower frame, cannon still closed in box form, aimed toward the central tower. A wide open sandy gap separates her from the nearest zombies. Dense horde advances from the tower direction through dust, ruins, and wrecks. Camera slowly pushes forward and slightly down. She plants one foot forward and raises the cannon into a stable firing stance. Hair and shirt hem move in the wind. 1.5-4.5s Front-side medium shot, one continuous uncut mechanical deployment. 1.5-2.0: Alin presses the control button with her right thumb, lowers her chin, sights along the cannon. Upper front cover lifts slightly, left and right covers hinge outward to reveal internal rails. Top optical unit stays fixed. Side circular cover stays intact and closed. 2.0-3.6: The muzzle frame slides forward along the weapon axis, pulling nested barrel sections out in stages. Primary rail extends first, then inner rail, then upper and lower link beams. Every section slides from a real parent sleeve with visible connections. Muzzle layout never rotates and never changes barrel count. Bottom extension beam advances with it. Bottom module stays under the main body, only small side cooling fins open slightly. Blue indicator lights turn on progressively as each connection reaches position. 3.6-4.5: The cannon reaches Image 3 deployed length and proportion. Rail ends brake, locks clamp in sequence, covers return and settle around the root while long exposed barrels and blue slots remain visible. Final heavy lock sound. Short sharp recoil-like settling vibration. Alin lowers her shoulders, bends deeper, leans slightly forward, keeps both hands fixed, and absorbs the weight shift. 4.5-6.0s Muzzle close shot then low-angle full-body charge-up. Keep muzzle layout readable: 8 large outer barrels, 4 small center holes. Blue-white internal charge travels from rear slots to the front. The 4 center holes light first, then the 8 outer barrels brighten together. A constrained bright core forms inside. Then low-angle full body: feet planted, knees bent, cannon tight to the body, jaw tense, eyes narrowed, cold light on her hair edges. 6.0-8.0s Over-shoulder shot along the cannon toward the horde and central tower, staying off the direct beam line. Front-row hoodie male, worker male, and office woman enter the fire lane at different positions and speeds. Around 6.6s the blue-white core surges and the fixed muzzle array emits parallel energy streams that merge into one straight orange-white beam: near-white core, orange outer edge, blue-white remains inside the weapon. The beam connects to the front line first, then impact flash and ground shock follow. Hit zombies are thrown backward along the force direction; side zombies are knocked outward by spread shock. No pre-hit explosions. Cannon kicks back shortly; Alin absorbs recoil through shoulders, elbows, knees, and boots grounded in sand. 8.0-11.0s High oblique overhead shot. Continue the same uninterrupted beam, no second charge cycle. The orange-white beam drives a straight corridor through the horde toward the central tower. Fire and impact waves move progressively along real contact points. Sand shockwaves expand outward close to the ground. Zombies, stones, and debris react in staggered timing by distance and force, not all at once. Around 10.7s the blast reaches the abandoned sedan near the central tower. The underside is lifted first by fire and sand blast, then the near side is hit harder, and the same damaged car is thrown into the air, tumbling diagonally toward the right side of the battlefield and into dust. Keep it recognizable as one whole car, not instantly shattered. 11.0-13.0s Low shot back on Alin. Same shot’s final firing phase: one last short muzzle flash, then the beam narrows and dies, no second shot. She bends deeper and stabilizes the cannon after recoil. White pressure-release steam vents from the rear body and bottom module outward and backward, away from her face and hands. Blue slot lights fade from front to rear. Cannon stays fully deployed. Hair and shirt settle with delayed motion. 13.0-14.3s Medium close-up past the cannon toward Alin. She keeps both hands holding the weapon and keeps looking forward. Her jaw slowly relaxes, she exhales softly, and one corner of her mouth lifts into a restrained, contemptuous, satisfied smile. No big grin, no look to camera. 14.3-15.0s Independent low camera on the right side of the battlefield, aimed toward dust near the central tower. The same launched sedan comes out of the dust along its existing arc, tumbling fast toward camera. First the twisted roof and empty windows are readable, then the heavy dark underside rotates toward lens. A broken door swings on its hinge, dragging dust and a few metal fragments. The car fills frame and blacks out the image at 15.0. No teleporting, no re-launch, no chasing Alin. Visual: Realistic metal, cloth, leather, sand, dust, sweat, and wear. Black iron weapon, white top, warm ochre wasteland, gray-blue sky. Side backlight on metal wear, hair strands, sweat sheen, dust. Blue-white charging and orange-white firing must be clearly different. Keep firing direction, muzzle array, Alin, and impacts readable. Sound: Low industrial electronic pulses and heavy drums, distant horde footsteps, hoarse zombie noises, wind and sand. Deployment sound layers: unlock clicks, hinge movement, sleeve sliding, rail braking, lock clamps, final heavy lock. Rising charge tone, sustained energy roar, air tearing, progressive impacts downrange. After firing: steam vent, Alin soft exhale, wind. Final car flyby: heavy rushing air and loose door slam. No dialogue, no narration. Do not: Do not change Alin’s face, hair, clothing structure, or body proportions. Do not generate beasts or giant monsters. Do not copy zombies, use synchronized marching, repeated clothing, or repeated faces. Do not alte
