## 修复内容
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
subtitle-renderer.py:
|
|||
|
|
- 原 burn_subtitles_to_video 只是占位，未真正合成多条字幕。
|
|||
|
|
- D144修复为 PNG输入 + overlay enable 分时叠加。
|
|||
|
|
- 修复中文字体加载，优先使用 macOS 中文字体。
|
|||
|
|
```

## 测试结果
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
PNG渲染: PASS
|
|||
|
|
FFmpeg合成: PASS
|
|||
|
|
中文字体: PASS
|
|||
|
|
字幕可读: PASS
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
观察:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
字幕位置位于底部偏上，适合竖屏短剧。
|
|||
|
|
黑色半透明底可读性够。
|
|||
|
|
当前样式可作为测试默认，不是最终商用字幕包装。
|
|||
|
|
```

## 裁决
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
status: PIPELINE_PASS_WRONG_BASE_VIDEO
|
|||
|
|
approved_for: 仅证明字幕管线可合成
|
|||
|
|
not_approved_for: 画面样片、视觉效果判断、最终商用字幕样式
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
D144补充纠偏:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
RUN-001误用了 TEST-COMP-001-SUBAI-PLAQUE-OVERLAY-RUN-001.mp4 作为底片。
|
|||
|
|
该底片本身已被判定为“牌匾压脸/位置失败”。
|
|||
|
|
因此RUN-001不能作为字幕视觉样片，只能证明字幕合成工具链可工作。
|
|||
|
|
|
|||
|
|
正确干净底片测试见:

|
|||
|
|
```
|
|||
|
|
|
|||
|
|
下一步:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
1. 把EP01每句原文台词转成正式SRT。
|
|||
|
|
2. 对角色对白音频做时长校准。
|
|||
|
|
3. 字幕按音频时间轴烧录。
|
|||
|
|
4. 建立商用字幕样式: 字体、描边、底色、位置、安全区。
|
|||
|
|
```
