实战案例：用AI提示词制作国产猫粮60秒情感TVC，从雨夜救助到双向奔赴的全片泪点

你是一位擅长宠物情感叙事的广告导演。灶边粮仓60秒品牌片分镜，原则：猫是主角，产品最后10秒才出现。

1. 情绪线：心疼（雨夜）→ 试探（带回家）→ 信任（陪伴日常）→ 破防（双向奔赴）→ 温暖（产品+品牌主张）
2. 时间线：
   - 0-10秒：雨夜，便利店门口纸箱里一只淋湿的小橘猫发抖，霓虹灯倒影在积水里
   - 10-22秒：女生用外套兜起小猫带回家，浴室擦干，小猫第一次试探性蹭手
   - 22-38秒：蒙太奇四季陪伴——合租屋窗台晒太阳、加班时猫蹲键盘、女生难过时猫过来贴脸
   - 38-50秒：泪点反转，深夜女生下班回家发现客厅留着灯，猫蹲在门口等她，脚边是它最爱的冻干
   - 50-60秒：清晨阳光厨房，倒粮特写（冻干双拼颗粒落碗），猫埋头吃，女生靠在门框笑，定格品牌主张「它把一生给了你，你把好粮给它」

3. 角色锚点（逐镜严格遵守）：
   - 猫：中华田园橘猫，白胸口白手套，琥珀色圆眼，右耳尖有一个小缺口（救助标记），幼猫期到成猫体型渐变但花纹不变
   - 女主：25岁左右，齐肩黑发，米色风衣+居家卫衣两套装束
   - 粮：浅棕色月牙形干粮颗粒混大块白色冻干鸡肉，哑光自立袋，橘色包装

4. 避坑：猫变品种/变花纹、六根胡须变三根、爪子畸形、夜戏死黑、颗粒像狗饼干、产品过早抢戏、猫表情拟人化挤眉弄眼

[镜头1：雨夜纸箱 0-10秒]
Rainy night outside a small Chinese convenience store, a soaked tiny orange tabby kitten with a white chest and white paws shivering inside a flattened cardboard box, neon sign reflections trembling in puddles, wet fur clumped in strands, the kitten's amber eyes looking up, handheld eye-level close shot slowly pushing in, moody teal-and-orange cinematic color, shallow depth of field, 4K, 10s
Audio: steady rain, distant car passing, faint convenience store hum, a single thin kitten meow near the end, gentle piano motif begins
[Negative] daytime, dry fluffy cat, cartoon cat, human-like expression, multiple cats, black underexposed frame, scary horror tone

[镜头2：外套兜起 10-16秒]
A young Chinese woman with shoulder-length black hair in a beige trench coat kneels under a transparent umbrella, lifts the shivering kitten gently wrapped inside her coat, the kitten peeking out from the warm fabric with only its head visible, rain streaming around them in soft focus, warm streetlight on their faces, over-shoulder close shot, 4K, 6s
Audio: rain softening under umbrella, fabric rustle, quiet reassuring whisper "走，回家", piano motif warming
[Negative] cat stretched unnaturally long, extra limbs, umbrella flipping inside out, daylight

[镜头3：擦干试探 16-22秒]
Warm small rental bathroom at night, the woman in a cream hoodie towel-dries the tiny orange tabby, fluff ball on the counter, the kitten leans forward and gives one cautious head-bonk to her fingertip, her expression softening, soft yellow tungsten light, intimate handheld close-up, 4K, 6s
Audio: towel rubbing, tiny purr, soft laugh, piano continuing

[镜头4：陪伴蒙太奇 22-38秒，三个2秒快切+一个4秒长镜]
4a. Same orange tabby now half-grown, napping on a sunlit windowsill above a radiator among small potted plants, dust motes floating, 2s
4b. The woman works late at a cluttered desk at night, the cat sits on her keyboard blocking the laptop screen, she peeks over its head trying to type, both lit by monitor glow, 2s
4c. She sits on the floor hugging her knees upset, the cat climbs into her lap and presses its cheek against hers, single warm floor lamp, 2s
4d. Continuous 4s shot: time-lapse feeling through one fixed apartment window, the same orange cat growing from kitten to adult on the same cushion as seasons change outside, white chest fur and ear notch unchanged, gentle dissolve transitions, 4s
Audio: purrs, keyboard taps, quiet sniffle then a relieved exhale, swelling warm strings entering over the piano
[Negative] cat changing breed or pattern, kitten and adult cat different colors, extra toes, stiff mannequin human, daylight in night scenes

[镜头5：深夜留灯 38-50秒]
Night, key turns in an apartment door, the tired woman enters in work clothes and stops mid-step: the living room lamp is on (she forgot to turn it off), her adult orange tabby sits upright by the entrance waiting, tail curled around paws, a few freeze-dried chicken pieces placed neatly beside its paws like a shared gift, it blinks slowly and meows once, she drops her bag and crouches down eyes glistening, warm lamp halo in dark hallway, slow dolly-in, 4K, 12s
Audio: keys, door, one soft meow, her breath catching, strings and piano reaching the emotional peak
[Negative] brand bag visible yet, dog, multiple cats, cartoon tear flood, daylight, scary dark corridor

[镜头6：倒粮晨光 50-60秒]
Morning sunlight kitchen, close product shot: a matte orange stand-up pouch tilts and crescent-shaped brown kibble mixed with large white freeze-dried chicken chunks pours into a ceramic bowl, the adult orange tabby eating eagerly with happy tail, the woman leans on the doorframe smiling softly, clean negative space upper-right reserved for brand line, warm hopeful commercial light, 4K, 10s
Audio: kibble pouring crisp sound, happy crunching, birds outside morning ambience, music resolving warmly
On-screen text safe area: 它把一生给了你，你把好粮给它

1. 品牌主张只在最后2秒出现：「它把一生给了你，你把好粮给它」，手写感中文字体，暖白色，不加价格（价格交给电商框）
2. 声音原则：全片以一只猫的三次叫声做结构锚点——雨夜细弱叫声、贴脸呼噜、门口等待的一声慢喵，音量依次放大
3. 音乐：钢琴单音起，22秒进弦乐，38秒峰值，倒粮时收回到温暖终止式，峰值必须卡在钥匙开门那一帧
4. 多版本：60秒旗舰店完整版；30秒小红书版删去四季蒙太奇保留雨→等待→倒粮；15秒抖音版只保留留灯反转+倒粮；9:16竖版重构图，纸箱和门口镜头给头顶留裁切余量
5. 封面A/B：A版淋湿小猫仰头（心疼向），B版猫守冻干在灯下等门（悬念向），B版预计30+女性人群评论率更高
