Luma Ray 3.2 video reframe. Generation is asynchronous: submit the request, then poll for the result URL.

- Resolution tiers:
540p,720p,1080p. - Billed per second of the source video.
- HDR is not available for reframe.
Parameters
| Parameter | Required | Description |
|---|---|---|
model | Yes | luma/ray-3.2/reframe |
video | Yes | Source video to reframe (publicly reachable HTTPS mp4 URL). It is probed to bill by source duration. |
aspect_ratio | Yes | Target aspect ratio (width:height) to reframe the source into. One of: 3:1, 2:1, 21:9, 16:9, 4:3, 3:2, 1:1, 3:4, 2:3, 9:16, 1:2, 1:3. |
prompt | Yes | Guidance for the reframe (e.g. what to keep in frame). |

How To Use
curl -X POST "https://api.atlascloud.ai/api/v1/model/generateVideo" \ -H "Authorization: Bearer $AIP_API_KEY" \ -H "Content-Type: application/json" \ --data-raw '{ "model": "luma/ray-3.2/reframe", "video": "https://static.atlascloud.ai/media/videos/example-landscape.mp4", "aspect_ratio": "9:16", "prompt": "Reframe to a vertical crop, keep the subject centered.", "resolution": "720p" }'

- Generation is asynchronous. Poll
/api/v1/model/prediction/{request_id}for the final URL. - The output is transferred to AtlasCloud storage before it is returned.
