Seedance 2.5 Apocalyptic Death Cannon Short Film Prompt

Seedance 2.5, 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 ruins. Broken industrial towers and wrecks surround the battlefield. The central tower is the only building intact. A burned, deformed abandoned sedan sits to the right of the central tower. Alin holds the heavy cannon with both hands: right hand on rear handle, left hand supporting the lower front 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 at the central tower. A wide open sandy gap separates her from the closest zombies. Dense horde advances from the tower side through dust. 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 wind. 1.5-4.5s Front-side medium shot, one continuous uncut mechanical deployment. 1.5-2.0s: Alin presses a button with her right thumb, lowers chin, sights along the cannon. Upper front cover lifts slightly, left and right covers open outward to reveal internal rails. Top optical unit stays fixed, side circular cover stays closed. 2.0-3.6s: 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. Every section slides from a real parent sleeve. Muzzle layout never rotates, never changes barrel count. Bottom extension arm advances too. Blue indicator lights turn on progressively as each connection snaps. 3.6-4.5s: The cannon reaches deployed length and proportion. Rails brake into place with mechanical clunks, sequential locks engage, covers retract. Final heavy lock thud. She absorbs the recoil shift with shoulders and legs. 4.5-6.0s Close shot of the muzzle and low-angle full body as it charges up. 8 large outer barrels, 4 small center holes, blue-white internal light travels from rear to front. The 4 center holes light first, then the 8 barrels brighten in unison. A contained bright core forms inside. Then low-angle full body: feet planted, knees bent, cannon tight to body, jaw tense, eyes narrow. 6.0-8.0s Over-shoulder shot along the cannon. Infected enter the firing lane. At 6.6s the light surges and the weapon fires: parallel energy streams merge into a single straight orange-white beam, center white, edge orange, with a blue-white core inside. The beam hits the front row instantly, then expands outward. Zombies are thrown backward in a wave, falling forced impacts. Cannon kicks; she absorbs recoil through shoulders and knees. 8.0-11.0s High oblique overhead shot. The same beam continues uninterrupted, no second charge. It sweeps a straight corridor through the crowd toward the central tower, fire and impact waves traveling along the path. Sand and debris burst outward in rings. Zombies and cars topple like dominoes. At 10.7s the blast reaches the abandoned sedan, lifts it underside first, then flips it over and sends it flying toward the camera side. 11.0-13.0s Low shot back to Alin. The beam narrows and dies, no second shot. She lowers the muzzle and steadies the weapon. Steam mouths from the rear grill, away from her face. The helmet lights fade. Her posture relaxes slightly. 13.0-14.3s Medium close-up past the cannon. She keeps both hands on the grip, lips pressed tight, one eyebrow raised, a faint satisfied, mocking smile. No victory pose, no eye contact with the camera. 14.3-15.0s Independent low-angle camera, side of the battlefield, facing the far dust. The same sedan exits the dust cloud along its ballistic arc, tumbling past, tumbling directly toward the lens. A door flops open, fuel leaks sparking, tires spin. The car smashes past and the screen fills with dust and blackout. Visual: Realistic metal, cloth, sand, dust, sweat, dirt. Black iron, white cloth, gray-blue sky, brown wasteland. Strong blowing dust. Muzzle flash bright orange, barrel burns dark. No glow-bloom. Blue-white charge versus orange-white fire. Sound: Percussive drums, low brass tips, effects. Mecha deployment clicks, hydraulic sighs, transformer whir, electric hum. Roar of charged fire, impact booms, debris skitters, engine scrape of the cruiser. After firing, the wind, dust settling, then her slow, uneven boots on sand. End on silence. Do not: Do not change Alin’s face, hairstyle, clothing, or body. Do not generate new guns or duplicates. Do not show cannons firing multiple times in one scene. Do not change muzzle array after secrets. Do not do freaky liquid-tank morphing, rubber expo transforms, elongated parts, or chest-recoil on the shoulder. Do not show faces that mirror the reference. Do not use names, has a language gap, or have a secondary character.
