[Generation Mode]Seedance 2.0[Video Specifications]Strict total duration of 15 seconds, 16:9 aspect ratio, 24fps, three clean shots.[Overall Style]Cinematic realistic texture, using a restrained deadpan sports comedy style, high-end commercial film lighting, silent film-style reaction pacing, and clear visual misdirection. It disguises an ordinary indoor cycling class as a grand cavalry charge; the final punchline is shared by both characters, avoiding realistic penalties, accidental falls, failed magic, or one-sided embarrassment.Designed for Seedance 2.0's unified multi-modal reference, dual-character stable movement, continuous camera spatial relationships, and native audio-visual synchronization for Mandarin dialogue, music, ambient sounds, and action sound effects.[Scene Setting]A dimly lit high-end indoor cycling studio. Black mirror walls, two rows of fixed exercise bikes, flowing red and blue lights, slight stage mist, folded towels, silver water bottles, continuously spinning wheels, and an empty instructor platform are clearly visible.[Characters]Character ID A | Sword Immortal SisterA 25–30 year old East Asian 'Sword Immortal' sister from @Image 1. Strictly maintain the same face from the reference image, sharp dark eyes, long black hair, jade hairpin, tall and slender build, white embroidered silk Hanfu, semi-transparent wide sleeves, silver accessories, fluttering long skirt, and white cloth boots.Character ID B | Cycling SisterThe same cycling sister from @Image 2. Strictly maintain the same face, ponytail, body proportions, clothing, shoes, and accessories.[Core Props]Two side-by-side fixed exercise bikes, folded towels, silver water bottles, empty instructor platform.[Shot 1 | 0-5s | Low-angle Full Shot Slow Tracking]Dim high-end indoor cycling studio. Character ID A, the 25–30 year old East Asian Sword Immortal sister from @Image 1, is fully seated on the frontmost fixed bike, hands gripping the handlebars, riding fast with a serious expression as if about to head into battle. Character ID B, the cycling sister from @Image 2, rides side-by-side with her. The camera tracks steadily forward from between the two bikes. Sounds of spinning wheels, chain rhythm, breathing, horse-hoof-like percussion, and heroic strings blend to create the illusion of thousands of troops charging.[Shot 2 | 5-10s | Cowboy Medium Shot Side Tracking]The same cycling sister lowers her upper body, pushes her cadence to the limit, and shouts: "Last ten seconds, charge!" The same Sword Immortal sister in white embroidered Hanfu stands up from the seat, hands gripping the handlebars, her long hair and wide sleeves fluttering violently backward. The cycling studio remains unchanged, but the red light trails and mirror reflections look like thousands of cavalrymen charging simultaneously. Their shoulders tremble from the effort, sweat beads appear naturally on their skin, yet they maintain a tragic and determined heroic expression as the music peaks.[Shot 3 | 10-15s | Close-up to Extreme Close-up]The heroic music stops abruptly, and ordinary white overhead lights flash on. An off-screen instructor announces calmly: "Warm-up finished, the formal class starts now." The same two women freeze simultaneously, slowly turn their heads to look at each other, and then both stop pedaling in unison. The Sword Immortal sister raises a slightly trembling hand and says seriously: "Cultivation requires gradual progress." The cycling sister immediately nods: "Agreed." Extreme close-up of their exhausted yet dignity-maintaining expressions, while the two wheels behind them continue to spin empty at high speed. Frame freeze.[Technical Requirements]Strict 15-second total duration, 16:9 wide screen, 24fps, three clean shots. Accurate Mandarin lip-sync, characters maintain clear left-right spatial relationships. Physical effects of pedaling, sweat, hair, silk fabric, wheels, and mirror reflections must be realistic. No generated captions, no added foreground figures.[Negative Prompt]blurry, bad quality, low quality, low resolution, noisy, jpeg artifacts, watermark, text, error; deformed, mutated, bad anatomy, poorly drawn hands, bad composition, out of frame, disfigured; inconsistent character, changing clothes, face morphing, background shift, glitching cuts, disappearing props
