## EP01默认样式
|
||
|
|
|
||
|
|
```
|
||
|
|
style_id: reference-drama
|
||
|
|
font_color: white / #FFFFFF / alpha 255
|
||
|
|
background: none
|
||
|
|
shadow: none
|
||
|
|

|
||
|
|

|
||
|
|

|
||
|
|
max_lines: 2
|
||
|
|
```
|
||
|
|
|
||
|
|
说明:
|
||
|
|
|
||
|
|
```
|
||
|
|
用户提供的商业样片字幕不是大号黑底字幕。
|
||
|
|
其特征是: 中等字号、白字、黑描边、贴近视频画面底部但不贴边。
|
||
|
|
因此默认改为 reference-drama。
|
||
|
|
```

## 为什么保留极细暗边
|
||
|
|
|
||
|
|
```
|
||
|
|
纯白字在天空、白衣、雾气、浅石头上会丢失。
|
||
|
|
黑描边不是阴影，也不是黑底。
|
||
|
|
它只用于保证手机观看时文字不发飘。
|
||
|
|
```
|
||
|
|
|
||
|
|
如果某个镜头背景很暗:
|
||
|
|
|
||
|
|
```
|
||
|
|
stroke_width可降为0。
|
||
|
|
```

## 质检标准
|
||
|
|
|
||
|
|
每次烧字幕后必须抽帧检查:
|
||
|
|
|
||
|
|
```
|
||
|
|
文字是否足够粗
|
||
|
|
颜色是否足够白
|
||
|
|
是否有黑底/阴影误启用
|
||
|
|
是否遮脸
|
||
|
|
是否遮关键道具
|
||
|
|
是否在手机安全区内
|
||
|
|
两行以内
|
||
|
|
与角色对白时间轴同步
|
||
|
|
```
