镜头衔接、声音设计,以及三道质量保障约束(负面 / 明亮 / 角色)。
描述与下一镜头的衔接,三段式:类型 + 持续时间 + 方向/风格。避免「smooth transition」等模糊表述。
| 类型 | 持续 | 示例 |
|---|---|---|
| hard cut 切镜 | 0 帧 | hard cut to next scene |
| fade in 淡入 | 0.5–1s | fade in from black, 0.5s |
| fade out 淡出 | 0.5–1s | fade out to white, 0.8s |
| dissolve 叠化 | 0.75–1.25s | slow dissolve, 1s overlap |
| wipe 划像 | 0.5–0.75s | horizontal wipe right, 0.5s |
| zoom 缩放转场 | 0.6–1s | zoom in to black, 0.7s |
三层描述法:环境音 + 音乐风格 + 音量层级。
示例:gentle ocean waves and seagull calls, ambient cinematic with strings and piano, peaceful, 70 BPM, volume level: balanced
distant traffic hum and occasional bird chirping,室内须指明混响no music, ambient sound only定义排除项,缺失会导致水印、模糊、文字错误等。通用负面词必须包含:
| 类别 | 关键词 |
|---|---|
| 文字 | no text, no watermark, no caption, no subtitle, no logo, no typography |
| 质量 | no blurry, no low resolution, no pixelated, no distorted, no artifacts |
| 解剖 | no extra limbs, no deformed hands, no malformed fingers, no fused fingers |
| 安全 | no nudity, no violence, no gore, no offensive content |
场景特定(按 content_type 加载):教育 no misleading diagram | 医疗 no inaccurate anatomy | 剧情 no breaking character | 广告 no competitor logo
no shadow)会导致画面僵硬;须与正面风格一致(正面要胶片质感,负面就不能 no grain)。总数控制在 15–25 个。所有镜头必填,从「建议性」升级为「强制性」亮度要求,杜绝暗场。四要素(整体→局部):
bright lighting, well-lit scene, clear visibility, no dark shadows on face, adequate illumination, face clearly lit
所有含角色的镜头必填,防止多角色混淆、分身、克隆。四项限制:
只出现[角色名]一人,禁止其他人物入镜,禁止同一角色重复出现,禁止角色分身或克隆
