# inference.partner.seedance-2-5.img2vid.v2

Source: https://docs.prodia.com/job-types/inference-partner-seedance-2-5-img2vid-v2/

The `inference.partner.seedance-2-5.img2vid.v2` job animates an input image into a video guided by a text prompt using Dreamina Seedance 2.5.

```json
{
  "type": "inference.partner.seedance-2-5.img2vid.v2",
  "config": {
    "image": "reference.png",
    "prompt": "a red fox trotting through a snowy forest at golden hour"
  }
}
```

## Parameters

Supports resolution, aspect ratio, duration (or automatic duration with `-1`), seed (`-1` or 0–2147483647), watermark, audio generation, and returning the last frame. See the job schema for model-specific limits and defaults.

Inputs are a first frame, or first and last frames. Use `aspect_ratio: "adaptive"`. Multimodal references use the separate `inference.partner.seedance-2-5.ref2vid.v2` type.

Set `duration` to `-1` for automatic duration. Automatic duration is determined from the prompt and reference content.
