时长与镜头：5 个镜头各 3 秒，全部是俯拍，机位统一，所以动画风也不容易乱。节奏是"脏—喷—搓—冲—亮"，每个镜头只做一件事，这是清洁类解压视频的标准结构。

怎么填变量：[旧鞋垫] 可换"[发黄的白球鞋]""[油污的灶台]""[起球的毛衣]"；喷瓶写你的产品外观（颜色、瓶型），不要写品牌名，品牌 Logo 留到片尾后期加。

常见失败与调整：

• 变成了写实风或 3D 风：在开头重复一次"2D 手绘动画，不是 3D"，并保留"避免"里的"真人实拍感、3D 渲染"。
• 手画崩了：手只露小臂以下，动作尽量简单；镜头 3 的打圈动作可以改成"海绵一抹而过"。
• 闪光特效太多、看着累：把"每次闪光配一声叮"改成只在镜头 4、5 出现。

提醒：用于产品广告时，清洁效果要与产品真实效果相符，不要夸大。

15-second vertical 9:16 Japanese 2D anime short, satisfying cleaning transformation. Hand-drawn cel animation look, clean black ink outlines, vivid colors, soft cel shading, manga-style editing with speed lines, halftone screentone dots, sparkle effects and white impact flashes. Studio-quality anime production, smooth motion, 24fps. Subject: a worn, dirty shoe insole (brown-gold stains, footprint imprint) lying on a brushed stainless steel counter, shot from directly above. An anime-style hand (no face, no body, only hand and forearm visible) holds a small black spray bottle with a green cap. Cool silver background with soft window light and tiny water droplets. Shot 1: Locked top-down shot, 3 seconds. The dirty insole lies on the steel counter, a hand presses it flat. Dust motes float, subtle halftone vignette at the corners, thin speed lines drift in from the edges. Shot 2: Close top-down shot, 3 seconds. The spray bottle sprays a fine mist onto the insole, thick white foam bursts outward and spreads across the surface, bubbles catching sparkles. A one-frame white impact flash with radial ink lines on the first burst of foam. Shot 3: Tight overhead shot, 3 seconds. The hand rubs the foam in circular motions, the brown-gold dirt dissolves into the white foam and streams toward the edge in curling ink-like swirls. Dynamic motion lines follow the hand. Shot 4: Overhead shot, 3 seconds. A rinse of clear water washes the foam away, the insole is flipped over in one quick whip motion, revealing a bright clean white surface. Glittering sparkles and shine streaks pop across it. Shot 5: Slow push-in from above, 3 seconds. The spotless white insole gleams on the steel counter, the hand sets the bottle down at the corner. Final sparkle burst, soft glowing light, manga-style screentone vignette, held for the last beat like a manga cover panel. Audio: crisp spray hiss, fizzing foam crackle, rhythmic scrubbing, flowing water, a bright sparkle chime on each shine effect, soft upbeat Japanese lo-fi beat underneath. No speech, no singing. Avoid: faces, realistic live-action look, 3D render, text, subtitles, logos, brand names, extra fingers, deformed hands, flicker.  15-second vertical 9:16 Japanese 2D anime, satisfying cleaning transformation, top-down shot. An anime-style hand (no face) sprays foam onto a dirty brown shoe insole on a stainless steel counter, scrubs the foam in circles, rinses it, and the insole turns bright clean white with sparkle effects. Manga-style speed lines, halftone dots, and a white impact flash on the first foam burst. Audio: spray hiss, foam crackle, scrubbing, water, light sparkle chimes, soft lo-fi beat. No faces, no text, no logos.
