# Wan Image to Video

The Wan Image to Video node generates a video from a single input image and a text prompt. It uses the provided image as the first frame and creates a video sequence based on the description, with options for resolution, duration, audio, and other advanced settings.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `model` | Model to use (default: "wan2.6-i2v") | COMBO | Yes | "wan2.5-i2v-preview"<br>"wan2.6-i2v" |
| `image` | Input image that serves as the first frame for video generation. Exactly one image is required. | IMAGE | Yes | - |
| `prompt` | Prompt describing the elements and visual features. Supports English and Chinese (default: empty). | STRING | Yes | - |
| `negative_prompt` | Negative prompt describing what to avoid (default: empty). | STRING | No | - |
| `resolution` | Video resolution quality (default: "720P"). The Wan 2.6 model does not support 480P. | COMBO | No | "480P"<br>"720P"<br>"1080P" |
| `duration` | Duration of the generated video in seconds. A 15-second duration is supported only by the Wan 2.6 model (default: 5). | INT | No | 5-15 (step: 5) |
| `audio` | Audio must contain a clear, loud voice, without extraneous noise or background music. When provided, audio duration must be between 3.0 and 29.0 seconds. | AUDIO | No | - |
| `seed` | Seed to use for generation (default: 0). | INT | No | 0-2147483647 |
| `generate_audio` | If no audio input is provided, generate audio automatically (default: False). | BOOLEAN | No | - |
| `prompt_extend` | Whether to enhance the prompt with AI assistance (default: True). | BOOLEAN | No | - |
| `watermark` | Whether to add an AI-generated watermark to the result (default: False). | BOOLEAN | No | - |
| `shot_type` | Specifies the shot type for the generated video, that is, whether the video is a single continuous shot or multiple shots with cuts. This parameter takes effect only when prompt_extend is True (default: "single"). | COMBO | No | "single"<br>"multi" |

**Constraints:**

- Exactly one input image is required for video generation.
- The Wan 2.6 model (`wan2.6-i2v`) does not support 480P resolution.
- A 15-second duration is supported only by the Wan 2.6 model (`wan2.6-i2v`).
- When audio is provided, it must be between 3.0 and 29.0 seconds in duration.

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `output` | Generated video based on the input image and prompt. | VIDEO |
