Sora2 Pro API overview

Sora2 Pro is a video generation model available on UniAll AI for creating short AI videos from text prompts or a reference image. The public model id is `sora2-pro-720p`.

It supports asynchronous generation, making it suitable for product videos, ads, short-form social clips, cinematic concepts, and automated creative workflows.

What Sora2 Pro supports

  • **Text to video**: generate a video from a written prompt.
  • **Image to video**: animate or transform one reference image with a prompt.
  • **Durations**: 4s, 8s, 12s, 16s, or 20s.
  • **Aspect ratios**: 16:9 and 9:16.
  • **Resolutions**: 720p, 1080p, and True 1080p.
  • **Output count**: 1 video per generation.
  • **API mode**: async task-based generation.

Sora2 Pro API pricing

Sora2 Pro is billed per generated video second. Pricing depends on the selected resolution:

| Resolution | User price | API price | Partner price | |---|---:|---:|---:| | 720p | $0.204 / second | $0.165 / second | $0.150 / second | | 1080p | $0.340 / second | $0.275 / second | $0.250 / second | | True 1080p | $0.476 / second | $0.385 / second | $0.350 / second |

Example: a 4-second 720p generation uses 4 billable seconds. Failed generations are refunded when the task fails.

Who should use Sora2 Pro

Sora2 Pro is a strong fit for:

  • Marketing teams producing short ad variations.
  • E-commerce teams creating product reveal videos.
  • Developers building AI video tools or automated content pipelines.
  • Agencies offering AI video generation to clients.
  • Creators who need 9:16 vertical clips or 16:9 cinematic shots.

API usage

Endpoint:

```http POST /v1/videos/generations ```

Example request:

```json { "model": "sora2-pro-720p", "generation_mode": "reference_image_to_video", "prompt": "A cinematic product reveal, soft studio lighting, smooth camera movement.", "image_url": "https://example.com/reference.png", "duration": 4, "aspect_ratio": "16:9", "resolution": "720p", "video_count": 1 } ```

For text-to-video, use `generation_mode: "text_to_video"` and omit `image_url`.

Required core parameters include `prompt`, `duration`, `resolution`, and `aspect_ratio`. For image-to-video, `image_url` is also required.

Pricing considerations

Choose 720p when speed and cost efficiency matter, such as testing prompts or generating social media drafts. Use 1080p or True 1080p for higher-quality production outputs, client delivery, or hero creative assets.

For high-volume usage, estimate cost by multiplying duration by the selected per-second price, then by the number of generations.
