      "text": "Create a 15-second ultra-realistic cinematic food commercial that captures the sensory journey of preparing and enjoying a gourmet meal. The tone is luxurious, warm, and indulgent, with high-end restaurant aesthetics, dramatic macro cinematography, and natural seamless transitions. Every shot should feel rich in texture and movement, emphasizing fire, steam, glossy sauces, and elegant plating.\n\nAudio Design\n\nUse a sophisticated soundtrack that begins with a deep cinematic bass note and soft sizzling sounds. As the video progresses, layer in subtle orchestral strings, crisp kitchen Foley (fire crackles, pasta falling, wine swirl, chocolate drizzle), and end with a warm, satisfying musical resolve. The sizzling should remain audible throughout the cooking shots, blending naturally with the music.\n\nVideo Prompt\nShot 1 — Steak Over Flame\n\nOpen with an extreme macro close-up of a thick steak searing over open fire. Bright orange flames dance around the meat, smoke curls upward, and rendered fat glistens on the charred crust.\n\nCamera: Slow push-in.\n Audio: Intense sizzling, fire crackle, cinematic bass hit.\n Transition: Flame flare naturally fills the frame and becomes the warm lighting of the next shot.\nShot 2 — Gourmet Table Spread\nTop-down cinematic sweep over a beautifully arranged table featuring grilled salmon with asparagus and rice, creamy pasta, Greek salad, and steak with dipping sauce.\n\nCamera: Smooth lateral pan.\n Audio: Music expands with soft strings and ambient restaurant sounds.\n Transition: Camera passes over a wine glass; the circular rim becomes the next shot.\n\nShot 3 — Elegant Diner\n\nClose-up of a glamorous blonde woman (late 20s, glowing skin, soft waves, glossy lips) holding a crystal wine glass and smiling subtly.\nCamera: Gentle dolly in.\n Audio: Delicate glass clink, soft music.\n Transition: She lowers her gaze toward the plate, cutting naturally to her hand.\nShot 4 — Lemon Squeeze\n\nMacro shot of her manicured hand with glossy red nails squeezing a charred lemon wedge over salmon. Slow-motion droplets sparkle as they fall.\n\nCamera: Tilt down following the juice.\n Audio: Bright citrus squeeze sound.\n Transition: The falling droplets match the motion of pasta entering sauce.\n\nShot 5 — Pasta Cascade\nWide ribbons of fresh pasta tumble from a colander into creamy sauce in slow motion.\nCamera: Overhead close-up.\n Audio: Silky pasta movement and bubbling sauce.\n Transition: Steam fills the frame and reveals the next shot.\n\nShot 6 — Salmon on Grill\n\nClose-up of salmon sizzling on a hot grill as a small flame ignites on its surface.\n\nCamera: Subtle zoom in.\n Audio: Sharp sizzle and brief flame burst.\n Transition: Flame flash cuts into red tomato sauce.\nShot 7 — Rigatoni Toss\nRigatoni is stirred with tongs in rich glossy tomato sauce.\n\nCamera: Circular overhead"

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.

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.

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.

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.

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.
