# Sora 2 Video Generation

This file is the focused AI-readable context for one UniAll documentation page.

URL: https://docs.uniall.ai/models/video/sora-2
Locale: en
Markdown: https://docs.uniall.ai/ai/pages/models/video/sora-2.md
Description: Generate videos with Sora 2 models through UniAll video APIs.

Agent guidance:
- Use this page when the user is asking about this specific route or model capability.
- Preserve endpoint paths, JSON keys, model IDs, and placeholder values exactly.
- Treat examples such as `sk-***`, `{BASE_URL}`, and `task_xxx` as safe placeholders, not real secrets.

## Page Markdown

Sora 2 supports prompt-based video generation with optional reference image input. The source scope includes the UniAll video generation endpoint and an OpenAI-native compatibility page.

## Supported Models

| Model | Notes |
| --- | --- |
| `sora2-landscape-4s` | Landscape output, 4 seconds. |
| `sora2-landscape-8s` | Landscape output, 8 seconds. |
| `sora2-landscape-12s` | Landscape output, 12 seconds. |
| `sora2-portrait-4s` | Portrait output, 4 seconds. |
| `sora2-portrait-8s` | Portrait output, 8 seconds. |
| `sora2-portrait-12s` | Portrait output, 12 seconds. |
| `sora2-pro-720p` | Pro public model, 720p. |
| `sora2-pro-1080p` | Pro public model, 1080p. |
| `sora2-pro-true-1080p` | Pro true-1080p model when enabled. |

## Endpoint

```http
POST /v1/video/generations
GET  /v1/videos/{task_id}
```

The source also includes a native OpenAI-format page for clients that need OpenAI-compatible request formatting.

## Authentication

```http
Authorization: Bearer sk-***
Content-Type: application/json
```

## Request Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `model` | string | Yes | Sora 2 model ID. |
| `prompt` | string | Yes | Video prompt. |
| `image_url` | string | No | Public reference image URL. |
| `aspect_ratio` | string | No | `16:9` or `9:16`. |
| `duration` | integer/string | No | Source description lists `4`, `8`, `12`, `16`, or `20`. Model names may already encode duration. |

## Request Example

```bash
curl -X POST "{BASE_URL}/v1/video/generations" \
  -H "Authorization: Bearer sk-***" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "sora2-portrait-12s",
    "prompt": "A cat running through grass",
    "image_url": "https://example.com/image.jpg"
  }'
```

## Submit Response

```json
{
  "id": "gen_xxxxxxxxxxxx",
  "object": "video.generation.job",
  "model": "sora2",
  "status": "queued",
  "progress": 0,
  "created_at": 1770405483,
  "seconds": "12"
}
```

## Query Task Status

```bash
curl "{BASE_URL}/v1/videos/gen_xxxxxxxxxxxx" \
  -H "Authorization: Bearer sk-***"
```

```json
{
  "id": "gen_xxxxxxxxxxxx",
  "object": "video.generation.job",
  "model": "sora2-portrait-12s",
  "status": "completed",
  "progress": 100,
  "video_url": "https://example.com/output.mp4",
  "seconds": "12"
}
```

## Billing Notes

Sora 2 billing depends on model, duration, orientation, resolution, and whether a Pro model is selected. Use the current model pricing surface and task settlement record as the source of truth.

## Common Errors

- Passing an unsupported Sora 2 model ID.
- Sending a private or expired `image_url`.
- Passing an `aspect_ratio` that conflicts with a landscape or portrait model name.
- Treating a queued task as complete before polling finishes.
- Mixing UniAll task format and native OpenAI format in one request.
