# ByteDanceTextToVideoNode - ComfyUI Built-in Node Documentation

> Complete documentation for the ByteDanceTextToVideoNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ByteDance Text to Video node generates videos using ByteDance models through an API based on text prompts. It takes a text description and various video settings as input, then creates a video that matches the provided specifications. The node handles the API communication and returns the generated video as output.

## Inputs

**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 `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.

## Outputs

| Output Name | Description              | Data Type |
