实战案例：用AI提示词制作精品咖啡品牌30秒TVC广告，从豆仓烘焙到城市清晨氛围感

你是一位咖啡品牌TVC广告创意总监。豆仓「云南保山铁皮卡」30秒TVC需要：

1. 时间线（30秒）：
   - 0-5秒：深夜豆仓烘焙车间，滚筒转动，咖啡豆从青转褐，爆裂声画外音
   - 5-12秒：清晨城市天台，阳光穿过玻璃窗，手冲壶水流螺旋注入滤杯
   - 12-20秒：咖啡液流入分享壶，琥珀色油脂光泽，特写液面波纹
   - 20-27秒：都市白领端着咖啡走过梧桐树下，晨光剪影
   - 27-30秒：豆仓Logo定格，画外音：「豆仓，从保山到你的清晨」

2. 色彩与质感：烘焙车间（暖橙+深棕+火光）、城市清晨（淡金+雾蓝+绿）、咖啡液（琥珀+深褐+油亮）
3. 运动镜头：烘焙用固定+特写推镜、手冲用慢动作跟拍、城市用手持跟拍
4. 避坑清单：咖啡变速溶、烘焙变爆米花、水流不自然、光线过曝

约束：整体温暖治愈；咖啡必须有油脂光泽；绝对不能速溶感；绝对不能廉价滤镜。

[镜头1：烘焙车间 0-5秒]
Cinematic close-up of coffee roasting drum rotating slowly, green coffee beans tumbling and gradually turning from pale green to rich dark brown, subtle smoke rising, warm orange fire glow reflecting on metal surfaces, dim industrial lighting, shallow depth of field, 4K, film grain, --motion 2 --duration 5s
[Negative] fast movement, plastic beans, too bright, cartoon, cheap lighting

[镜头2：手冲水流 5-12秒]
Slow motion extreme close-up of pour-over coffee brewing, clear spiral water stream pouring from gooseneck kettle into white ceramic dripper, hot water creating gentle bloom in coffee grounds, morning sunlight streaming through window blinds in background, warm side light, 4K, shallow depth of field, --motion 1 --duration 7s
[Negative] broken water stream, no bloom, artificial light, too fast

[镜头3：咖啡液特写 12-20秒]
Macro close-up of amber coffee liquid pouring into glass carafe, rich crema foam swirling on surface, light refraction creating golden highlights through translucent liquid, slow motion ripple on liquid surface, warm studio side light, 4K, --motion 1 --duration 8s
[Negative] murky brown, no crema, flat color, too dark

[镜头4：城市清晨 20-27秒]
Cinematic wide shot of young professional woman walking under plane trees in autumn morning, holding takeaway coffee cup, golden morning light filtering through leaves creating dappled shadows, gentle breeze moving leaves, handheld camera slightly shaky for documentary feel, 4K, --motion 2 --duration 7s
[Negative] harsh sunlight, no leaves, plastic cup, no atmosphere

[镜头5：Logo定格 27-30秒]
Clean brand logo reveal on warm cream background, subtle coffee bean texture fading in behind logo, soft golden glow, smooth fade-in transition, elegant serif font style, 4K, --motion 0 --duration 3s

[配乐建议]
轻爵士吉他+口哨开头，温暖治愈，音量不盖过画面氛围，结尾logo处音乐微微上扬

1. 交付规格：30秒成片，4K 30fps，H.264编码，16:9横版+9:16竖版两个版本
2. 平台适配：抖音/视频号用9:16加字幕条「豆仓·云南保山铁皮卡」，门店循环用16:9无字幕
3. 色彩统一：整体色温5500K-6000K暖调，避免冷蓝
4. 声音要求：环境音（烘焙爆裂声、水流声）大于配乐，增强沉浸感
