# Vidu3StartEndToVideoNode - ComfyUI Built-in Node Documentation

> Complete documentation for the Vidu3StartEndToVideoNode 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 the Vidu Q3 model to create a seamless transition between the two images, producing a video of a specified duration and resolution.

## Inputs

| Parameter          | Description                                                                                                                                           | Data Type | Required | Range                                |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------ |
| `model`            | The model to use for video generation. Selecting an option reveals additional configuration parameters for `resolution`, `duration`, and `audio`.     | COMBO     | Yes      | `"viduq3-pro"`<br />`"viduq3-turbo"` |
| `model.resolution` | Resolution of the output video. This parameter is revealed after selecting a `model`.                                                                 | COMBO     | Yes      | `"720p"`<br />`"1080p"`              |
| `model.duration`   | Duration of the output video in seconds (default: 5). This parameter is revealed after selecting a `model`.                                           | INT       | Yes      | 1 to 16                              |
| `model.audio`      | When enabled, outputs video with sound (including dialogue and sound effects) (default: False). This parameter is revealed after selecting a `model`. | BOOLEAN   | Yes      | `True` / `False`                     |
| `first_frame`      | The starting image for the video sequence.                                                                                                            | IMAGE     | Yes      | -                                    |
| `end_frame`        | The ending image for the video sequence.                                                                                                              | IMAGE     | Yes      | -                                    |
| `prompt`           | A text description guiding the video generation (maximum 2000 characters).                                                                            | STRING    | Yes      | -                                    |
| `seed`             | A seed value for controlling the randomness of the generation (default: 1).                                                                           | INT       | No       | 0 to 2147483647                      |

**Note:** The `first_frame` and `end_frame` images should have similar aspect ratios for optimal results. The aspect ratio of the two images must be within 80% to 125% of each other (a relative closeness between 0.8 and 1.25).

## Outputs

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