# Vidu2StartEndToVideoNode - ComfyUI Built-in Node Documentation

> Complete documentation for the Vidu2StartEndToVideoNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node generates a video by interpolating between a provided start frame and an end frame, guided by a text prompt. It uses a specified Vidu model to create a smooth transition between the two images over a set duration.

## Inputs

| Parameter            | Description                                                                              | Data Type | Required | Range                                                         |
| -------------------- | ---------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------------------------------- |
| `model`              | The Vidu model to use for video generation.                                              | COMBO     | Yes      | `"viduq2-pro-fast"`<br />`"viduq2-pro"`<br />`"viduq2-turbo"` |
| `first_frame`        | The starting image for the video sequence. Only a single image is allowed.               | IMAGE     | Yes      | -                                                             |
| `end_frame`          | The ending image for the video sequence. Only a single image is allowed.                 | IMAGE     | Yes      | -                                                             |
| `prompt`             | A text description guiding the video generation (maximum 2000 characters).               | STRING    | Yes      | -                                                             |
| `duration`           | The length of the generated video in seconds (default: 5).                               | INT       | No       | 2 to 8                                                        |
| `seed`               | A number used to initialize the random generation for reproducible results (default: 1). | INT       | No       | 0 to 2147483647                                               |
| `resolution`         | The output resolution of the generated video.                                            | COMBO     | No       | `"720p"`<br />`"1080p"`                                       |
| `movement_amplitude` | The movement amplitude of objects in the frame.                                          | COMBO     | No       | `"auto"`<br />`"small"`<br />`"medium"`<br />`"large"`        |

**Note:** The `first_frame` and `end_frame` images must have similar aspect ratios. The node will validate that their aspect ratios are within a relative range of 0.8 to 1.25.

## Outputs

| Output Name | Description               | Data Type |
| ----------- | ------------------------- | --------- |
| `output`    | The generated video file. | VIDEO     |
