The ByteDance Image to Video node generates videos using ByteDance models through an API based on an input image and text prompt. It takes a starting image frame and creates a video sequence that follows the provided description. The node offers various customization options for video resolution, aspect ratio, duration, and other generation parameters.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `model` | The ByteDance model to use for video generation (default: `"seedance-1-0-pro-fast-251015"`). | STRING | Yes | `"seedance-1-5-pro-251215"`<br>`"seedance-1-0-pro-250528"`<br>`"seedance-1-0-lite-i2v-250428"`<br>`"seedance-1-0-pro-fast-251015"` |
| `prompt` | The text prompt used to generate the video. Must be at least 1 character long after trimming whitespace. | STRING | Yes | - |
| `image` | First frame to be used for the video. 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"`<br>`"1080p"` |
| `aspect_ratio` | The aspect ratio of the output video. | 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). For the `seedance-1-5-pro-251215` model, the minimum supported duration is 4 seconds. | INT | Yes | 3 - 12 |
| `seed` | Seed to use for generation (default: 0). | INT | No | 0 - 2147483647 |
| `camera_fixed` | Specifies whether to fix the camera. The platform appends an instruction to fix the camera to your prompt, but does not guarantee the actual effect (default: False). | BOOLEAN | No | - |
| `watermark` | Whether to add an "AI generated" watermark to the video (default: False). | BOOLEAN | No | - |
| `generate_audio` | This parameter is ignored for any model except `seedance-1-5-pro-251215` (default: False). | BOOLEAN | No | - |

**Note:** The prompt must not contain the following words (case-insensitive): `resolution`, `ratio`, `duration`, `seed`, `camerafixed`, `watermark`. These parameters are set via their dedicated inputs.

## Outputs

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