# ByteDanceImageToVideoNode - ComfyUI Built-in Node Documentation

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

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
