Generated with Seedance 2.0
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.
Generated with Seedance 2.0
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.
Generated with Seedance 2.0
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.
Generated with Seedance 2.0
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.
Generated with Seedance 2.0
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.
Generated with Seedance 2.0
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.
