# Vidu3StartEndToVideoNode - ComfyUI Built-in Node Documentation

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

This node generates a video by creating a transition between a start frame and an end frame, guided by a text prompt. It uses the Vidu Q3 model to interpolate between the two images and produces a video at the chosen duration and resolution.

## Inputs

### Common Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `model` | 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 of the video sequence. | IMAGE | Yes | - |
| `end_frame` | The ending image of the video sequence. | IMAGE | Yes | - |
| `prompt` | Prompt description (max 2000 characters). | STRING | Yes | Up to 2000 characters |
| `seed` | Seed value used to control the randomness of the generation. Has a control-after-generate option (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 appear after a model is selected.

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `resolution` | Resolution of the output video. | COMBO | Yes | `"720p"`<br />`"1080p"` |
| `duration` | Duration of the output video in seconds (default: 5). | INT | Yes | 1 to 16 |
| `audio` | When enabled, outputs video with sound (including dialogue and sound effects) (default: False). | 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 stay within 80% to 125% of each other (relative closeness between 0.8 and 1.25).

**Note:** For `viduq3-turbo`, the price is 0.06 USD per second at 720p and 0.08 USD per second at 1080p. For `viduq3-pro`, the price is 0.15 USD per second at 720p and 0.16 USD per second at 1080p.

## Outputs

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