实战案例：用AI提示词制作智能投影仪45秒秋冬品牌片，从一句卖点到三代同堂观影TVC（Veo 3）

你是拍过家电品牌秋冬campaign的广告导演。把「一台机器，点亮全家的客厅」这句卖点拆成一支45秒、6个镜头的家庭投影仪品牌片分镜表，时间轴精确到秒。
产品：星昼XINGZHOU智能投影仪，外观锚点=矮胖金属圆筒机身（深空灰磨砂铝）、正面深灰色编织织物面罩、顶部一圈细窄金色星轨触控环、投射比短、摆放在客厅边几上。
情绪曲线：黄昏归家（暖）→ 孩子放学看动画（活泼）→ 奶奶陪孙子看国风动画（温情）→ 夫妻深夜电影（浪漫松弛）→ 清晨关机收束（安静）。
要求：每个镜头给出【时长/景别/机位/人物动作/墙面画面内容/光线色温/同期声】七列，不要台词，靠画面与音效叙事；全片人物固定为四位：爸爸（35岁短发）、妈妈（33岁马尾）、女儿小夏（6岁双马尾）、奶奶（65岁银灰短发戴细框眼镜），不得增减家庭成员。

[镜头2·开机，5秒，16:9]
Cinematic product film shot, a compact matte dark-gray aluminum cylinder smart projector sitting on a light-oak side table in a modern Chinese apartment living room at dusk, woven dark-fabric acoustic mesh on its front face, one thin golden star-track touch ring glowing softly on its flat top, warm tungsten lamp light, the projector powers on and a soft cone of light beams toward a blank white wall where a glowing family animation opening frame fades in, shallow depth of field, dust particles in the light cone, cozy autumn mood, slow push-in, no people
Negative: square box projector, plastic glossy body, visible brand text, fake logo letters, light hitting ceiling, image on wrong surface, lens flare overload, deformed cylinder

[镜头3·祖孙动画时光，8秒]
Medium side shot, a 65-year-old Chinese grandmother with short silver-gray hair and thin-frame glasses sitting on a fabric sofa with her 6-year-old granddaughter Xiaoxia (double ponytails, yellow knit sweater), both seen mostly from behind and side silhouette watching a white living-room wall, on the wall a stylized Chinese ink-wash animation of a little deer under a full moon is clearly projected, warm soft projector light on their faces, grandmother gently puts hand on child's shoulder, gentle smile, evening, cozy, slow handheld breathing
Cast lock: exactly two people in frame, grandmother silver hair glasses, girl double ponytail yellow sweater
Negative: three or five people, extra fingers, child suddenly older, deformed hands, turned-around faces melting, ink animation appearing on floor, bright cinema theater seats, subtitles, text watermark

[镜头4·深夜电影，8秒]
Wide shot from behind a couple on the same sofa late at night under a blanket, man 35 short hair, woman 33 ponytail, both relaxed leaning together, only the projected light from the front wall illuminates the room, on the wall a romantic snowy mountain night scene plays with subtle flickering light, the golden star-track ring on the cylinder projector on the side table glints once, blue-amber cinematic color grade, quiet intimate mood, static camera
Negative: additional people, daylight, TV with black bezel instead of wall projection, popcorn buckets, multiple projectors, ghost faces

为这支45秒家庭投影仪品牌片生成Veo 3原生音轨，无对白，按镜头给出环境声与情绪音乐：
镜头1黄昏归家：钥匙开门声、外套摩擦、远处城市晚高峰低频；
镜头2开机：安静室内一声轻微触控提示音、风扇极轻转动白噪音；
镜头3祖孙：水墨动画笛声若隐若现、孩子轻轻笑声一次、沙发织物声；
镜头4深夜电影：极弱钢琴和弦pad、毯子摩擦、远处一声冬风；
镜头5清晨：鸟鸣、窗帘拉开、机器柔和关机提示音。
整体响度-16LUFS，音乐不压环境声，禁止任何可识别的现成歌曲旋律。

把以下16:9镜头扩展重构图为9:16竖版，保持产品与人物不变，只调整取景：竖版中投影仪位于画面下三分之一、墙面投影占据上三分之二；人物镜头改为胸部以上竖构图，祖孙镜头让两人上下错落而非左右并排；严禁新增任何人物、物体与文字。逐镜输出后附一句构图说明。
