# ByteDanceImageReferenceNode - ComfyUI Built-in Node Documentation

> The ByteDance Image Reference Node generates videos using a text prompt and one to four reference images.

The ByteDance Image Reference Node generates videos using a text prompt and one to four reference images. It sends the images and prompt to an external API service that creates a video matching your description while incorporating the visual style and content from your reference images. The node provides various controls for video resolution, aspect ratio, duration, and other generation parameters.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `model` | The AI model to use for video generation (default: `"seedance-1-0-lite-i2v-250428"`). | STRING | Yes | `"seedance-1-0-pro-250528"`<br />`"seedance-1-0-lite-i2v-250428"` |
| `prompt` | The text prompt used to generate the video. | STRING | Yes | - |
| `images` | One to four images. Each image must be between 300x300 and 6000x6000 pixels, with an aspect ratio between 0.4 and 2.5. | IMAGE | Yes | - |
| `resolution` | The resolution of the output video. | STRING | Yes | `"480p"`<br />`"720p"` |
| `aspect_ratio` | The aspect ratio of the output video (default: `"adaptive"`). | STRING | Yes | `"adaptive"`<br />`"16:9"`<br />`"4:3"`<br />`"1:1"`<br />`"3:4"`<br />`"9:16"`<br />`"21:9"` |
| `duration` | The duration of the output video in seconds (default: 5). | INT | Yes | 3 - 12 |
| `seed` | Seed to use for generation (default: 0). | INT | No | 0 - 2147483647 |
| `watermark` | Whether to add an "AI generated" watermark to the video (default: False). | BOOLEAN | No | - |

**Note:** The prompt text must not contain the following parameter strings: `--resolution`, `--ratio`, `--duration`, `--seed`, or `--watermark`. These values are controlled exclusively through their dedicated input widgets.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `output` | The generated video file based on the input prompt and reference images. | VIDEO |
