# Vidu3StartEndToVideoNode - ComfyUI Built-in Node Documentation

> This node generates a video by interpolating between a provided start frame and an end frame, guided by a text prompt.

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

### Common 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`. | DYNAMIC\_COMBO | Yes      | `"viduq3-pro"`<br />`"viduq3-turbo"` |
| `first_frame` | The starting image for the video sequence.                                                                                                        | IMAGE          | Yes      | -                                    |
| `end_frame`   | The ending image for the video sequence.                                                                                                          | IMAGE          | Yes      | -                                    |
| `prompt`      | Prompt description (max 2000 characters).                                                                                                         | STRING         | Yes      | -                                    |
| `seed`        | A seed value for controlling the randomness of the generation (default: 1).                                                                       | INT            | Yes      | 0 to 2147483647                      |

### viduq3-pro and viduq3-turbo Inputs

The following parameters are shared by both model options (`viduq3-pro` and `viduq3-turbo`). They are revealed after a model is selected.

| Parameter    | Description                                                                                                                                           | Data Type | Required | Range                   |
| ------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------- |
| `resolution` | Resolution of the output video. This parameter is revealed after selecting a `model`.                                                                 | COMBO     | Yes      | `"720p"`<br />`"1080p"` |
| `duration`   | Duration of the output video in seconds (default: 5). This parameter is revealed after selecting a `model`.                                           | INT       | Yes      | 1 to 16                 |
| `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`<br />`False`     |

**Note:** The `first_frame` and `end_frame` images must have similar aspect ratios. 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     |
