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.

## API Endpoint {#api-endpoint}
|
|
|
|
`POST /api/v1/tools/video/video-loudnorm`
|
|

|
接受包含一個影片檔案的 multipart form data。此工具沒有可設定的選項。
|
|
|
|
## Parameters {#parameters}
|
|

此工具沒有參數。它會對音訊軌套用 EBU R128 響度正規化。
|
|
|
|
## Example Request {#example-request}
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/video/video-loudnorm \

## Example Response {#example-response}
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",

|
|
}
|
|
```
|
|
|
|
## Notes {#notes}
|
|
|
|
- 使用 FFmpeg 的 `loudnorm` 濾鏡，以 -16 LUFS 整合響度、-1.5 dBTP 真實峰值和 11 LU 響度範圍（EBU R128 廣播標準）為目標。
|
|
- 來源音訊取樣率會在輸出中保留。
|
|
- 若影片沒有音訊軌，請求會回傳 400 錯誤。
