## Video Generation

Video generation uses OpenRouter's `/api/v1/videos` endpoint with a **submit-and-poll** pattern orchestrated by a background worker:
1. `POST /api/v1/videos` with `model`, `prompt`, `aspect_ratio`, `resolution`, `duration_seconds`
2. Response: `{"id": "job_id", "polling_url": "https://..."}` with `status: "queued"`
3. Poll `GET polling_url` every 5 seconds until `status` is `"completed"` or `"failed"`
4. Completed response includes `unsigned_urls: [str]` array with video download URLs
1. User submits a video request via `POST /generate/video` (or `/generate/video/from-image`)
2. Backend inserts a row into `generated_videos` with `status: "queued"` and returns immediately
3. Background worker (`video_worker.py`) picks up queued jobs every 15 seconds:
- Calls `POST /api/v1/videos` with `model`, `prompt`, `aspect_ratio`, `resolution`, `duration`
- Receives `{"id": "job_id", "polling_url": "https://..."}` and updates DB to `status: "processing"`
- Polls `GET polling_url` every 15 seconds until `status` is `"completed"` or `"failed"`
- Updates DB with final status, `video_url`, and any `error` message
4. Frontend polls `GET /generate/video/{db_id}/status` every 5 seconds to show live updates
5. Completed response includes `video_url` — the video is displayed in a `<video>` element
Supported models: `openai/sora-2-pro`, `google/veo-3.1-fast`. Both text-to-video and image-to-video use the same `/api/v1/videos` endpoint (image-to-video includes `image_url` in the request body).
