镜头1:痛点场景(凌乱客厅)
▶ 视觉提示词:
"modern messy living room, coffee stains on light wood floor, golden retriever fur floating in air, dim lighting from curtains, fisheye lens perspective, 35mm film grain, realistic texture"
▶ 负面提示词:
"clean floor, neat arrangement, bright lighting, cartoon style"
▶ 关键参数:
- 基础模型:RealisticVision V6.0
- 分辨率:2048x1152 → 裁剪为21:9电影画幅
- 采样器:DPM++ 3M SDE Karras (25 steps)
- ControlNet:Depth+OpenPose 控制人物姿势
▶ 镜头运动控制:
- 初始帧:俯视全景 → 结束帧:女主面部特写
- 运镜参数:Zoom rate -0.3/sec(匀速推进)
▶ 特效实现:
- 咖啡渍动态扩展:在Runway用「Image to Video」输入首帧后,添加prompt:"coffee stain slowly spreading"
- 毛发飘动:用Pika的「Motion Brush」涂抹毛发区域,强度设置70%
镜头2:床底清洁(产品介入)
▶ 视觉提示词:
"cyberpunk style robotic vacuum cleaner with blue headlight, sliding under bed in dark environment, dust particles being sucked into machine, cinematic lighting, octane render, industrial design close-up"
▶ 负面提示词:
"cartoon robot, bright environment, static dust"
▶ 关键参数:
- 基础模型:Juggernaut XL V9 + CyberRealistic混合
- LoRA加载:<mechanical_detail_v2> (权重0.7)
- 动态控制:在Pika设置「Motion Intensity」=8,「Fluidity」=6
▶ 物理模拟技巧:
1. 先用Blender生成洗地机基础模型三视图
2. 在ComfyUI使用「AI Texture」插件生成金属材质
3. 灰尘吸附效果:在After Effects添加Particular粒子系统(导出单帧后AI补间)
▶ 光效优化:
- 探照灯轨迹:用Runway的「Directional Light」工具定义光源路径
- 吸尘光效:在提示词添加"volumetric light with dust occlusion"
镜头3:杀菌过程(微观视角)
▶ 视觉提示词:
"scientific microscope view, water molecules splitting into hydrogen and oxygen, coronavirus being destroyed by electric current, cinematic macro photography, 8k ultra detailed, blue and gold energy particles"
▶ 负面提示词:
"hand drawing, low contrast, blurry details"
▶ 生物准确性保障:
1. 使用Midjourney生成基础病毒模型(Prompt:"coronavirus 3D model, photorealistic, studio lighting")
2. 在Runway用「Video Style Transfer」应用《新神榜:杨戬》特效风格
3. 用DaVinci Resolve添加电解水分解的粒子动态路径
▶ 关键帧控制:
- 0-2秒:病毒完整形态旋转
- 2-3秒:电流击穿病毒表面尖刺(局部重绘)
- 3-4秒:分子结构分解爆破(Pika的「Explosion」预设)
镜头4:家庭温馨场景
▶ 视觉提示词:
"Japanese modern family kitchen, warm sunlight through window, steaming hotpot on wooden table, laughing chinese family, shallow depth of field, Fujifilm XT4 film simulation"
▶ 焦点转移实现:
1. 生成两张图:
- 图A:洗地机蒸汽特写(提示词:"steam rising from metal surface, macro lens")
- 图B:家庭聚餐全景(提示词:"multi-generational family dinner, natural interactions")
2. 在Runway用「Multi Motion」分别设置:
- 图A:Zoom out + 虚化增强(Blur从0%→100%)
- 图B:Focus shift(Blur从100%→0%)
▶ 光影一致性技巧:
- 使用Krea的「Style Reference」功能锁定暖色调
- 在人物面部添加0.3强度的「Soft Glow」避免AI面部畸形
通用参数优化建议
1. 测试优先级:
- 先跑通「床底探照灯」镜头(技术难度最高)
- 用512x512小图批量生成备选场景,再选优放大
2. 成本控制技巧:
- 静态镜头用「静帧+运镜」替代全动态生成
- 分层渲染:背景/前景/特效分层生成后合成
3. 物理规律校准:
- 添加「gravity effect:0.7」避免毛发漂浮失真
- 用「fluid dynamics」参数控制水流运动
4. 产品一致性保障:
- 训练专属LoRA:用洗地机多角度白底图微调模型
- 在提示词锁定特征:"red Xiaomi logo on silver body"
