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

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/Vidu2StartEndToVideoNode/en.md)

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

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