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.

# Compress Video {#compress-video}
|
|
|
|
使用可配置的压缩强度和可选的分辨率降采样来减小视频文件大小。
|
|
|
|
## API Endpoint {#api-endpoint}
|
|
|
|
`POST /api/v1/tools/video/compress-video`
|
|
|
|
接受包含视频文件和 JSON `settings` 字段的 multipart 表单数据。这是一个异步端点：它会立即返回 `202 Accepted`，进度通过 SSE 在 `GET /api/v1/jobs/{jobId}/progress` 处流式传输。
|
|
|
|
## Parameters {#parameters}
|
|
|
|
| Parameter | Type | Required | Default | Description |
|
|
|-----------|------|----------|---------|-------------|
|
|
| quality | string | No | `"balanced"` | 压缩强度：`light`、`balanced`、`strong` |
|
|
| resolution | string | No | `"original"` | 输出分辨率：`original`、`1080p`、`720p`、`480p` |
|
|
|
|
## Example Request {#example-request}
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/video/compress-video \
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|
-F "file=@clip.mp4" \
|
|
-F 'settings={"quality": "strong", "resolution": "720p"}'
|
|
```
|
|
|
|
## Example Response {#example-response}
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"async": true
|
|
}
|
|
```
|
|
|
|
## Notes {#notes}
|
|
|
|
- `light` 预设可保留接近原始的质量。`strong` 预设以牺牲视觉保真度为代价，激进地减小文件大小。
|
|
- 降低分辨率（例如从 4K 降到 720p）与压缩叠加，可显著减小文件大小。
|
|
- 在任务完成前，可通过 SSE 在 `GET /api/v1/jobs/{jobId}/progress` 处获取进度更新。
