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

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/ByteDanceTextToVideoNode/en.md)

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.

**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.
