All 181 docs markdown files translated into 20 languages (apps/docs/<locale>/**). Companion to the i18n code PR; admin-merged because the file count exceeds GitHub's per-PR CI trigger limit. Validated by pnpm i18n:check (all surfaces, 0 stale/missing) and a clean all-locale docs build.

| Parameter | Type | Required | Default | Description |
|
||
|-----------|------|----------|---------|-------------|
|
||
| target | string | No | `"16:9"` | 目标宽高比：`16:9`、`9:16`、`1:1`、`4:3`、`3:4` |
|

|
||
|
||
## Notes {#notes}
|
||
|
||
- 模糊值越高，背景越柔和、越抽象。值越低，保留的细节越多。
|
||
- 如果视频已经匹配目标宽高比，则文件将原样返回。
|
||
- 若要使用纯色填充，请改用 Aspect Pad 工具。
