# Vidu Q3 Start/End Frame-to-Video Generation

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 |
