实战案例：用AI提示词制作低温烘焙狗粮品牌人宠陪伴30秒广告，从晨跑相伴到雨夜等候的温情大片

你是一位拍过皇家、冠能级别品牌片的宠物广告导演，擅长人宠情感叙事。为新锐低温烘焙狗粮品牌「烤一勺」（品牌名后期，画面不出现文字）制作一支30秒16:9电影感品牌广告。

【主角狗·每个镜头必须严格一致】
品种：中华田园犬与柴犬混血（shiba mix rescue dog），姜黄色双层被毛，胸口一撮月牙形白毛，右耳直立左耳略塌，琥珀色眼睛，鼻头有一小块旧伤疤（tiny scar on left edge of nose），体型精瘦约11公斤，戴深橄榄绿色织带项圈无吊牌
性格动作：中段年龄成年犬，步态稳健不蹦跳，开心时尾巴平缓摇摆不是疯狂转圈，眼神始终跟随主人
【主角人】30岁左右短发女生，藏青色连帽卫衣+卡其裤，不露完整正脸（多为侧脸/手部/背影），避免抢戏
【产品锚点】深绿色自立袋犬粮（袋身标签留白，后期贴标）；颗粒为深褐色圆角方形小方块、表面粗糙多孔哑光，不是圆球不是彩色
【叙事线30秒】
0-6s 清晨：江边绿道，人与狗并肩慢跑，狗在左侧半步位置，呼吸白雾
6-13s 雨夜：家门口脚垫上狗趴着等门，窗上雨水，路灯暖光，耳朵微动
13-22s 回家：门开灯亮，狗起身上前迎接但不扑跳，女生蹲下抱住狗脖子
22-30s 喂食：陶瓷碗倒入颗粒的微距，狗缓慢咀嚼尾巴轻摇，最后人狗并排坐在地板上，slogan区后期
【物理铁律】狗永远四条腿一条尾巴；奔跑时背部有真实的脊椎起伏；爪子落地有重量感；颗粒从袋中倒出是干燥哑光的颗粒流，不反光不粘连

[Shot1 0-6s 晨跑跟拍]
A woman in navy hoodie and a 11kg ginger shiba-mix dog with a white crescent chest patch, one upright ear and one slightly folded ear, running side by side on a riverside running track at dawn, dog positioned half a step behind her left leg, realistic canine trot gait with spine undulation, paws landing with weight, light breath fog in cool air, shallow depth of field, handheld tracking shot, cinematic 16:9, photoreal, 6s
Audio: steady paw steps on pavement, calm breathing, soft morning ambient, gentle piano motif begins
Negative: extra legs, two tails, dog breed changing mid-shot, fluffy pomeranian, bouncing cartoon run, glowing eyes, human facing camera, text

[Shot2 6-13s 雨夜等候]
Interior doorway at night, the same ginger shiba-mix dog with white crescent chest patch lying on a woven doormat, chin resting on front paws, one ear twitching at a distant elevator sound, rain streaming on the frosted window behind, warm sodium streetlight glow, occasional passing car light sweeping across, lonely but peaceful mood, slow dolly-in, 16:9, 7s
Audio: muffled rain, distant traffic, single piano notes, collar tag must NOT jingle (no tag on collar)
Negative: puppy, different breed, extra ears, plush toy eyes, wet cartoon tears, dramatic lightning, multiple dogs

[Shot3 13-22s 开门迎接]
Apartment door opens from inside, warm hallway light spills out, the same ginger shiba-mix dog rises from the doormat and walks calmly to the woman, tail wagging in smooth relaxed sweeps (not spinning), she crouches down and wraps arms around his neck, dog presses head against her shoulder, eyes half closed, authentic restrained joy, no jumping, 16:9, 9s
Audio: door keys, soft click of nails on floor, quiet happy huff, piano melody opens up
Negative: dog jumping on person, excessive licking, human full face visible, deformed arms, six fingers, two dogs, toy-like eyes

[Shot4 22-27s 颗粒微距]
Extreme macro product shot, matte dark-brown square-ish rounded kibble pieces with rough porous surface pouring from a deep-green stand-up pouch (blank unprinted label area) into a cream ceramic dog bowl, dry matte pieces tumbling with realistic small clatters, a few crumbs, warm kitchen side light, ultra-detailed food commercial texture, 16:9, 5s

[Shot5 27-30s 碗边收尾]
The dog eating slowly beside the kitchen cabinet, genuine chewing motion with visible jaw and cheek movement, tail gently sweeping the floor; after a few bites he looks up toward the woman sitting on the floor beside him; she places hand on his back; both in profile, warm practical light, clean upper-third area reserved for Chinese tagline added in post, 16:9, 3s
Post: slogan与品牌logo全部后期合成，画面禁止任何文字
Negative: mouth morphing, kibble passing through jaw, deformed paw, cartoon, text, watermark

一致性质检与修复任务，逐镜检查并只重跑不合格镜头：
1. 品种表：逐帧确认姜黄色、月牙白毛、右立左耳塌、鼻头伤疤四个锚点；任何镜头串成柴犬纯血或金毛，用角色卡原句+该镜头描述重新生成，不改动其他镜头
2. 解剖表：腿数=4、尾巴=1、耳朵=2；奔跑帧爪子必须在地面或合理腾空弧线，禁止滑行
3. 眼神测试：眼睛必须有环境反光点（catchlight），没有反光点的填充玩具眼重跑
4. 时长校准：五个镜头导入剪辑后总时长29.5秒±0.3，镜头间用动作接动作（狗起身→走向主人）而非硬切
5. 15秒电商版结构：颗粒微距3s → 咀嚼摇尾4s → 晨跑高光4s → 抱狗+品牌定格4s，前3秒必须出现食物

1. 声音设计：全片不用旁白，靠钢琴motif串情绪；爪子踩地、钥匙、颗粒倒碗、咀嚼四个拟音必须近景真实；雨夜段禁止雷声这种廉价煽动
2. 音乐节点：6秒处收住晨跑节拍进入雨夜单音，13秒门开旋律释放，27秒回到安静主题
3. 调色：晨跑青蓝冷调→雨夜暖橙路灯→室内统一琥珀暖调，狗的姜黄毛色在冷调段落不能发灰
4. 合规：不出现「治疗/预防/处方/最好」等词；不与婴儿或儿童共食画面；品牌名、「低温烘焙」卖点字幕全部后期；不生成任何认证标志
5. 封面：选Shot3抱狗侧脸帧做B站封面，颗粒微距帧做电商主图视频首帧
