}# xai/grok-imagine-video/extend-video
> xAI Grok Imagine Video continues an existing 2-15s mp4 with a 2-10s prompt-driven extension. Output matches input, capped at 720p.
## Overview
- **Submit endpoint (POST)**: `https://api.atlascloud.ai/api/v1/model/generateVideo` — start an async generation; returns a `prediction_id`
- **Poll endpoint (GET)**: `https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}` — poll this until the prediction finishes
- **Model ID**: `xai/grok-imagine-video/extend-video`
## API Information
This model can be used via our HTTP API or more conveniently via our client libraries.
See the input and output schema below, as well as the usage examples.
### Input Schema
The API accepts the following input parameters:
- **`model`** (`string`, _required_):
Model name.
- Default: `"xai/grok-imagine-video/extend-video"`
- **`prompt`** (`string`, _required_):
Natural-language description of what should happen after the input video's last frame.
- **`video_url`** (`string`, _required_):
Public URL of an mp4 file (H.264/H.265/AV1, etc.). Input duration must be 2–15 seconds.
- **`duration`** (`integer`, _optional_):
Length of the extension segment in seconds. Range: 2–10 (default 6). Total returned video = input duration + extension. Output is capped at 720p.
- Default: `6`
- Min: 2
- Max: 10
**Required Parameters Example**:
```json
{
"model": "xai/grok-imagine-video/extend-video",
"prompt": "",
"video_url": ""
}
```
**Full Example**:
```json
{
"model": "xai/grok-imagine-video/extend-video",
"prompt": "",
"video_url": "",
"duration": 6
}
```
### Output Schema
The API returns the following output format:
- **`id`** (`string`, _optional_):
Unique identifier for the prediction.
- **`urls`** (`object`, _optional_):
Object containing related API endpoints.
- **`model`** (`string`, _optional_):
Model ID used for the prediction.
- **`status`** (`string`, _optional_):
Status of the task: created, processing, completed, or failed.
- **`outputs`** (`array[string]`, _optional_):
Array of URLs to the generated video (empty when status is not completed).
- **`created_at`** (`string`, _optional_):
ISO timestamp of when the request was created.
- **`has_nsfw_contents`** (`array[boolean]`, _optional_):
Array of boolean values indicating NSFW detection for each output.
**Example Response**:
```json
{
"id": "",
"urls": {},
"model": "",
"status": "",
"outputs": [
""
],
"created_at": "",
"has_nsfw_contents": []
}
```
## Usage Examples
### cURL
```bash
# Step 1: Start generation (async)
curl -X POST "https://api.atlascloud.ai/api/v1/model/generateVideo" \
-H "Authorization: Bearer $ATLASCLOUD_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "xai/grok-imagine-video/extend-video",
"prompt": "",
"video_url": "",
"duration": 6
}'
# Response will contain: {"code": 200, "data": {"id": "prediction_id", "status": "processing"}}
# Step 2: Poll for result (replace {prediction_id} with the id returned above)
curl -X GET "https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}" \
-H "Authorization: Bearer $ATLASCLOUD_API_KEY"
# Keep polling until status is "completed", "succeeded" or "failed"
# When completed, outputs will contain the generated content URL(s)
```
