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.

# Trim Video {#trim-video}
|
|
|
|
通过以秒为单位指定起止时间，从视频中剪出片段，并可选择帧精确剪辑。
|
|
|
|
## API Endpoint {#api-endpoint}
|
|
|
|
`POST /api/v1/tools/video/trim-video`
|
|
|
|
接受包含视频文件和 JSON `settings` 字段的 multipart 表单数据。
|
|
|
|
## Parameters {#parameters}
|
|
|
|
| Parameter | Type | Required | Default | Description |
|
|
|-----------|------|----------|---------|-------------|
|
|
| startS | number | No | `0` | 起始时间，单位为秒（必须 >= 0） |
|
|
| endS | number | Yes | - | 结束时间，单位为秒（必须晚于 startS） |
|
|
| precise | boolean | No | `false` | 重新编码以实现帧精确剪辑，而非关键帧定位 |
|
|
|
|
## Example Request {#example-request}
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/video/trim-video \
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|
-F "file=@clip.mp4" \
|
|
-F 'settings={"startS": 5, "endS": 30, "precise": true}'
|
|
```
|
|
|
|
## Example Response {#example-response}
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",
|
|
"originalSize": 12500000,
|
|
"processedSize": 4200000
|
|
}
|
|
```
|
|
|
|
## Notes {#notes}
|
|
|
|
- 当 `precise` 为 `false`（默认）时，工具使用关键帧定位，速度快，但可能在所请求时间之前几帧开始。
|
|
- 将 `precise` 设置为 `true` 会重新编码该片段以获得精确的帧边界，但耗时更长。
|
|
- `endS` 值必须大于 `startS`。
