## Integration Guide
**1. Prepare a Source Video and a Background Image**
The output must be in MP4 format with the same resolution as the input, a frame rate capped at 30 frames per second with automatic conversion if the input exceeds this limit, and a maximum duration of 600 seconds with only the first 600 seconds retained if the input video is longer.
The background image must be in JPG or PNG format with a maximum resolution of 4096 by 4096 pixels with the long side not exceeding 4096 pixels and a file size limit of 10 megabytes.
**2. Upload File**
Request upload URLs and file IDs via:

```
POST /s2s/v2.0/file
```
**3. Execute AI Task**

```
POST /s2s/v2.0/task/bg-replace-vid
```
Submit the task using file IDs or image URLs as input. The response returns a task_id for tracking and retrieving the result.
**4. Retrieve Task Result**

```
GET /s2s/v2.0/task/bg-replace-vid/{task_id}
```
Use the task ID to track status and obtain results.
[Webhooks](/develop/webhook) can be configured to receive asynchronous notifications on task completion with a success or error status. Polling is also supported by repeatedly calling the task endpoint until the status is updated from running to success or error.
Usage is only charged when the task completes successfully.
