实战案例：用AI提示词制作智能宠物喂食器20秒众筹短片，从猫咪第一视角到双结局成片（Veo 3+即梦）

你是拍过宠物用品众筹campaign的广告导演，擅长猫狗情感向短片。把「它等的不是饭，是你」拆成一支20秒、9:16竖版众筹片头，结构=4个共用镜头+2个可选结局镜头（主人在家版/主人加班版），精确到秒。
产品：饭点FANDIAN智能喂食器，外观锚点=奶白色磨砂圆角机身、顶部半圆透明粮仓（能看到猫粮存量）、正面一颗黑色摄像头（工作时微弱红点）、下方圆形不锈钢食盆、底部一圈浅木色防滑垫。
卡司：固定一只猫，编号C1，橘白英短（背部橘色斑纹、胸口与四爪白色、圆脸蛋、铜黄色大眼睛），全片只有这一只猫。
镜头语言：大量猫眼高度的第一视角POV（视高约15cm、广角、轻微呼吸晃动），结尾才出现人的视角。
要求：每镜给【时长/景别/机位/猫的动作/产品状态/光线/同期声】七列；功能点（定时出粮、APP远程、双向语音）要自然嵌入动作而非念台词；无台词，仅手机消息提示音与猫叫。

A single ginger-and-white British Shorthair cat sitting on a warm wooden floor, C1 character reference: orange tabby patches on back and head, white chest and four white paws, round chubby cheeks, big copper-amber eyes looking straight into camera, soft morning window light, shallow depth of field, photorealistic pet photography, 9:16 vertical, clean simple living room background, no text
Negative: dog, kitten too small, green eyes, blue glowing eyes, cartoon, different coat pattern, two cats, collar with tag, text, watermark

[镜头2·猫眼POV走向喂食器，5秒，9:16]
Cat first-person POV at 15cm eye height, wide angle with subtle breathing wobble, walking across a sunlit wooden living room floor toward the Fandian feeder: a matte cream-white rounded-corner smart pet feeder with a half-dome transparent hopper on top showing brown dry cat kibble level, a single black camera lens on its front with a faint tiny red recording dot, a round stainless steel bowl below, light-wood non-slip base ring. C1's own white paw tips occasionally enter bottom of frame. The feeder is silent and closed, cat waits, looks up. Cozy morning light, dust motes, realistic home, 5 seconds
Product lock: cream-white matte rounded feeder, transparent half-dome hopper, black camera with red dot, steel bowl
Negative: third person view, human standing height, dog, multiple cats, dog bones in bowl, wet food, meat, blue eye glow, red dot becoming bright alarm lamp, text, app UI

[镜头3·APP远程出粮，4秒]
Close-up at cat-eye height, the cream-white feeder's small front dispensing chute opens with a soft mechanical click, a small portion of small round brown cat kibble pellets (uniform dry pellets, NOT bones, NOT meat) tumbles into the stainless steel bowl, the black camera's red dot glows faintly once, a smartphone notification chime sound, C1 orange-white cat eagerly approaches from right edge, copper eyes, warm kitchen light, shallow DOF
Negative: dog food bone shapes, wet canned food, giant pile overflowing, sparks, blue light, text on feeder, cartoon

[结局A·开门拥抱，5秒，9:16]
Warm human eye-level shot (NOT cat POV), apartment front door opens with golden evening light, a young woman steps in and crouches down with open arms, SAME ginger-white cat C1 from reference (white chest, copper eyes) runs to her across wooden floor tail up, the cream feeder visible softly blurred in background, emotional reunion, handheld warmth, lens flare from doorway, no dialogue
Negative: different cat, dog, man instead of woman, two women, cat flying, deformed running legs, text

[结局B·加班远程陪伴，5秒，9:16]
Late night, human eye-level shot of empty dark apartment, only the cream-white feeder area lit by a warm lamp, close-up of a smartphone on a table showing a BLANK generic video-call interface (empty UI, no text, no brand, just a silhouette of a cat in the feed), the woman's hand reaches in and taps screen, cut to: SAME cat C1 looking up at the feeder camera ears perked, red dot glows, kibble gently drops, cat eats calmly, faint warmth, city lights blurred through window
Negative: readable text, gibberish letters, app logo, different cat, dog, scary red light, multiple cats
