"text": "[Style]\nModern Rural Aesthetics, cinematic commercial quality, shot on Sony A7S3/cinema camera, 4K/8K ultra-high definition, extreme macro, natural and transparent light, healing ASMR, no period drama feel.\n\n[Scene]\nA well-organized modern farmhouse open kitchen, with a lush vegetable garden in the background, bathed in bright sunlight.\n\n[Character]\nModern rural creator, with long black hair casually tied up with a wooden hairpin, wearing a deep blue comfortable linen set (modern linen outfit), light and clear makeup, focused and serene eyes.\n\n[Storyboard Details]\n[00:00-00:05] Shot 1: Morning Harvest (The Freshness)\nVisual: High-definition close-up. Morning sunlight casts a side-backlight on the plants.\nAction: The creator's bare hands (slender and clean fingers) pick a bright red tomato with glistening dew from the vine.\nDetails: Extremely sharp focus, revealing the fine hairs on the tomato's surface and the trail of water droplets sliding down. The background is a blurred, premium green.\n\n[00:05-00:10] Shot 2: Ultimate Craftsmanship (The Craft)\nVisual: Indoor stove area, full of life yet spotless.\nAction: The creator is cutting vegetables, movements skilled and efficient (not performative).\nDetails: Macro lens captures the moment the blade slices through the ingredients, with juice splashing. Then cut to the dancing orange flames in the earthen stove, warm and authentic light and shadow.\n\n[00:10-00:15] Shot 3: Quiet Time (The Moment)\nVisual: Full shot/medium shot.\nAction: A delicate home-cooked dish is placed on a rustic wooden table in the yard. The creator sits down quietly, gently tucks a stray strand of hair behind her ear, and picks up a bite of food.\nAtmosphere: Steam rises slowly against the backlight, the scene is so quiet you can almost hear the wind, embodying the ultimate sense of relaxation that modern people long for."

使用 Seedance 2.0 生成
Creative direction: An original hand-drawn adult woman in a yellow raincoat waits on a rain-soaked railway platform beside a red umbrella. She opens and reads a white letter; the camera pushes from the platform view into her worried close-up and holds on her reaction. Visual treatment: Rainy anime drama with cool platform light and yellow-red costume accents. Shot sequence: 1. Establish the yellow raincoat and red umbrella on the wet platform.; 2. Move closer as the woman opens the white letter and lowers her gaze.; 3. Hold her worried close-up with the letter still below her eyeline. Continuity: Keep the character's face, clothing and key prop consistent; preserve screen direction across cuts. Exclude: extra people or props, text, logos and watermarks.
使用 Seedance 2.0 生成
Creative direction: A coral-orange insulated bottle stands on a wet dark-teal studio surface beside a clear glass and a few ice cubes. One adult hand unscrews the cap and pours cold water over the ice, then sets the bottle beside the filled glass. End on a clean product hero frame with both bottle and glass visible. Visual treatment: Photoreal product commercial. A soft overhead key reveals the matte coral finish; a cool cyan edge light picks out condensation and the restrained floor reflection. Shot sequence: 1. Open on condensation and ice in a tight detail shot; 2. Cut to a steady three-quarter view for the cap opening and single pour; 3. Settle on the bottle and chilled glass together, with the bottle silhouette unobstructed Continuity: Keep the product silhouette, cap or hinge, materials and prop positions stable; hold the final hero frame. Exclude: extra people or props, text, logos and watermarks.
使用 Seedance 2.0 生成
Creative direction: A man enters an old circular observatory at dawn and approaches a vintage telescope beneath the dome. Begin behind him in a wide view, track inward as a warm shaft crosses the instrument, then hold on the telescope against the cool interior. Visual treatment: Live-action film previs with warm dawn shafts against a cool aged interior. Shot sequence: 1. Frame the man entering the circular observatory from behind.; 2. Track his approach as dawn light crosses the vintage telescope.; 3. Settle with the telescope and figure against the cool dome interior. Continuity: Maintain scene geography, subject scale and motivated light direction throughout the camera move. Exclude: extra people or props, text, logos and watermarks.
使用 Seedance 2.0 生成
Creative direction: An orange-suited astronaut walks through a dark hangar toward a massive grounded machine. The camera follows from behind as work lights flicker on and the machine powers up with blue-white light, ending on the figure beneath its scale. Visual treatment: Science-fiction game cinematic with orange fabric, dark metal and blue-white practical lights. Shot sequence: 1. Follow the orange-suited astronaut from behind into the hangar.; 2. Continue forward as work lights illuminate the grounded machine.; 3. Hold the small figure beneath the machine as blue-white power light stabilizes. Continuity: Maintain character design, equipment geometry and travel direction from first to final frame. Exclude: extra people or props, text, logos and watermarks.
使用 Seedance 2.0 生成
Creative direction: A researcher at a wooden table unrolls an old map, traces a route with one finger, and examines a marked point with a small brass instrument. Alternate between the hands, parchment details, and a measured medium view of the archival workspace. Visual treatment: Live-action archival demonstration with warm parchment, brass and natural skin texture. Shot sequence: 1. Show the researcher unrolling parchment on the wooden table.; 2. Cut closer as one finger follows the route and the brass instrument approaches the marked point.; 3. Return to a measured medium view with the map orientation unchanged. Continuity: Keep demonstration props, layout and hand contact consistent so the action remains legible. Exclude: extra people or props, text, logos and watermarks.
使用 Seedance 2.0 生成
Creative direction: A male musician performs on an electronic keyboard and sampler in a blue-and-purple studio. Cut between his focused medium profile and close views of both hands playing keys and controls while colored practical lights remain steady behind him. Visual treatment: Live-action studio performance with saturated blue-purple practical light. Shot sequence: 1. Establish the musician in profile at the keyboard and sampler.; 2. Cut to fingers depressing keys and then operating the sampler.; 3. Return to the profile while the blue-purple practical lights stay steady. Continuity: Keep the main subject, palette and light behavior consistent as the visual pattern develops. Exclude: extra people or props, text, logos and watermarks.
