# Resize Video {#resize-video}
|
|||
|
|
|
|||
|
|
使用自訂像素尺寸或標準預設,將影片縮放至新的解析度。
|
|||
|
|
|
|||
|
|
## API Endpoint {#api-endpoint}
|
|||
|
|
|
|||
|
|
`POST /api/v1/tools/video/resize-video`
|
|||
|
|
|
|||
|
|
接受包含一個影片檔案和一個 JSON `settings` 欄位的 multipart form data。
|
|||
|
|
|
|||
|
|
## Parameters {#parameters}
|
|||
|
|
|
|||
|
|
| Parameter | Type | Required | Default | Description |
|
|||
|
|
|-----------|------|----------|---------|-------------|
|
|||
|
|
| width | integer | No | - | 目標寬度(以像素為單位,16-7680) |
|
|||
|
|
| height | integer | No | - | 目標高度(以像素為單位,16-4320) |
|
|||
|
|
| preset | string | No | `"custom"` | 解析度預設:`custom`、`2160p`、`1440p`、`1080p`、`720p`、`480p`、`360p` |
|
|||
|
|
|
|||
|
|
當 `preset` 為 `"custom"` 時,必須至少提供 `width` 或 `height` 其中一個。另一個尺寸會按比例縮放。
|
|||
|
|
|
|||
|
|
## Example Request {#example-request}
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
curl -X POST http://localhost:1349/api/v1/tools/video/resize-video \
|
|||
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|||
|
|
-F "file=@clip.mp4" \
|
|||
|
|
-F 'settings={"preset": "720p"}'
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
縮放至自訂尺寸:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
curl -X POST http://localhost:1349/api/v1/tools/video/resize-video \
|
|||
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|||
|
|
-F "file=@clip.mp4" \
|
|||
|
|
-F 'settings={"width": 1280, "height": 720}'
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Example Response {#example-response}
|
|||
|
|
|
|||
|
|
```json
|
|||
|
|
{
|
|||
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|||
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",

|
"originalSize": 25000000,
|
|||
|
|
"processedSize": 8500000
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Notes {#notes}
|
|||
|
|
|
|||
|
|
- 預設值對應到標準高度(例如 `720p` = 1280x720、`1080p` = 1920x1080)。寬度會依來源長寬比按比例縮放。
|
|||
|
|
- 尺寸會四捨五入為偶數,因為大多數影片編解碼器都有此要求。
|
|||
|
|
- 支援的最大解析度為 7680x4320(8K UHD)。
