Seedance 2.5 蓝色铅笔把现实画成动画 抽象特效提示词

Style: Cinematic live-action seamlessly blended with 2D hand-drawn line-art animation, using a playful rotoscoping-inspired transformation effect. Visual Direction: First-person POV throughout. A hand holding a blue pencil appears at the bottom of the frame, seemingly tracing over real-world objects. Wherever the pencil moves, the live-action environment gradually transforms into expressive 2D illustrations. Scene Transitions & Subjects: - Train: A white-and-green train travels across an elevated urban overpass. As the blue pencil traces along it, the train smoothly converts into clean black-and-white sketch line art, while retaining its movement and perspective. - Cat: An orange tabby cat casually walks along a paved sidewalk. The pencil follows its movement, transforming the cat into a white hand-drawn cartoon with stylized illustrated shadows. - Bus: A light-colored compact bus drives through the street. As it passes beneath the pencil’s tracing path, it morphs into a colorful pastel illustration with loose, artistic hand-drawn outlines. - Girl: A woman sits naturally on a bench in a narrow urban alley, looking at her phone. The pencil traces around her and the surroundings, seamlessly turning the scene into a stylized 2D color-block illustration. Tone & Atmosphere: Bright natural daylight, contemporary urban environment, playful and whimsical mood, fluid camera movement, dynamic transformations, and seamless transitions between realistic footage and hand-drawn animation. Overall Effect: The video should feel as though the blue pencil is literally drawing reality into an animated world, with each subject transforming organically rather than appearing as a sudden cut or visual effect.
