## 经验总结(来自 Chloe《樱花落尽时》项目)

### 图像生成最佳实践
| 项目 | 推荐 | 备注 |
|------|------|------|
| 模型 | qingyun `gpt-image-1` | 成功率最高 |
| API | `/v1/images/generations` | 比 edits 更稳定 |
| 尺寸 | `1024x1536`(竖版) | 必须用规定尺寸 |
| 并发 | 2-3 并发 | 过多会 SSL EOF |
| 重试 | 失败单独重试 | 不整批重跑 |

### 角色一致性技巧
- **统一 prompt prefix**: 包含角色核心外貌特征
- **参考图**: 用 edits API 传入角色头像(但成功率低)
- **场景限定词**: 每帧 prompt 固定前缀 + 场景变量

### 音频同步
- 用 `mutagen` 读 MP3 时长(无需 ffprobe)
- 场景时间按歌曲结构比例分配
- BPM 检测需 `librosa`(可选)

### 视频模型选择
| 情绪 | 模型 | 场景类型 |
|------|------|---------|
| ≤ 6.0 | kling-1.6 | 静态/自然/国风 |
| 6.0-8.0 | kling-1.6 或 kling-2 | 过渡 |
| ≥ 8.0 | kling-2 | 爆发/力量 |
| 360°旋转 | veo-3.1 | 特殊运镜 |

## 依赖
- Python: mutagen, requests
- 外部 API: qingyun (图像), xingjiabi (视频), Google (veo-3.1)
- 可选: librosa (BPM), ffmpeg (合成)
