# Vidu4ImageToVideoNode - ComfyUI Built-in Node Documentation
> Generate a video from a start frame and an optional prompt with a Vidu Q4 model.
Generate a video from a start frame and an optional prompt with a Vidu Q4 model. The output keeps the aspect ratio of the input image.
Selecting a `model` reveals the parameters specific to that model.
## Inputs
| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `image` | Start frame of the generated video. Aspect ratio must be between 1:5 and 5:1. | IMAGE | Yes | N/A |
| `model` | Model to use for video generation. Selecting a model reveals the parameters specific to it: `prompt`, `resolution`, `duration`, `audio`, and `seed`. | DYNAMIC\_COMBO | Yes | `"Vidu Q4 Preview"` |
| `prompt` | An optional text prompt for video generation, up to 5000 characters (default: empty). | STRING | Yes | Any text |
| `resolution` | Resolution of the output video (default: `"720p"`). | COMBO | Yes | `"540p"`
`"720p"`
`"1080p"`
`"2K"`
`"4K"` |
| `duration` | Duration of the output video in seconds (default: 5). | INT | Yes | 3 to 16 |
| `audio` | When enabled, outputs video with sound, including dialogue and sound effects (default: True). | BOOLEAN | Yes | `True`
`False` |
| `seed` | Seed controls whether the node should re-run; results are non-deterministic regardless of seed. This parameter has "control after generate" functionality (default: 42). | INT | Yes | 1 to 2147483647 |
**Note:** The aspect ratio of `image` must stay between 1:5 and 5:1, and the `prompt` cannot exceed 5000 characters. The result keeps the aspect ratio of the input image, so the output size follows the `resolution` setting only within that ratio.
## Outputs
| Output Name | Description | Data Type |
| - | - | - |
| `VIDEO` | The generated video file. | VIDEO |
