# ByteDanceTextToVideoNode - ComfyUI Built-in Node Documentation

> The ByteDance Text to Video node generates a video using ByteDance models through an API based on a text prompt.

The ByteDance Text to Video node generates a video using ByteDance models through an API based on a text prompt. You provide a prompt and choose settings such as the model, resolution, aspect ratio, and duration; the node submits the generation request and returns the generated video.

## Inputs

| Parameter        | Description                                                                                                                                                           | Data Type | Required | Range                                                                                              |

| `duration`       | The duration of the output video in seconds (default: 5).                                                                                                             | INT       | Yes      | 3 to 12                                                                                            |
| `seed`           | Seed to use for generation (default: 0).                                                                                                                              | INT       | No       | 0 to 2147483647                                                                                    |
| `camera_fixed`   | Specifies whether to fix the camera.

| `generate_audio` | This parameter is ignored for any model except `seedance-1-5-pro-251215` (default: False).                                                                            | BOOLEAN   | No       | -                                                                                                  |

**Parameter Constraints:**

* The `prompt` parameter must contain at least 1 character after whitespace removal.
* The `prompt` parameter cannot contain the following text parameters: "resolution", "ratio", "duration", "seed", "camerafixed", "watermark".
* The node builds the final prompt by appending the selected `resolution`, `aspect_ratio`, `duration`, `seed`, `camera_fixed`, and `watermark` settings to the prompt text.
* The `duration` parameter is limited to values between 3 and 12 seconds. For the `seedance-1-5-pro-251215` model, the minimum supported duration is 4 seconds.
* The `seed` parameter accepts values from 0 to 2,147,483,647.
* The `generate_audio` parameter only has an effect when the `model` is set to `seedance-1-5-pro-251215`; it is ignored for all other models.
