GrokVideoNode - ComfyUI Built-in Node Documentation

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

The Grok Video node generates a short video from a text description. It can create a video from scratch using a prompt or animate a single input image based on a prompt. The node sends a request to an external API and returns the generated video.
