The 'Grok: Reference to Video' workflow in ComfyUI is designed to transform static reference images into dynamic video content. This workflow leverages the Grok API to create videos that maintain high visual consistency across frames, even when using up to six reference images. The process begins with the 'LoadImage' node, where you can upload your reference images. These images are then processed by the 'GrokVideoReferenceNode', which utilizes the Grok model to interpret and transform the static visuals into a coherent video sequence. Finally, the 'SaveVideo' node allows you to export the generated video for use in various applications.
What sets this workflow apart is its ability to handle multiple reference images, ensuring that the resulting video maintains a consistent style and character portrayal. This is particularly useful for projects requiring character animation or consistent artistic style across video frames. The Grok model's advanced capabilities allow for nuanced interpretation of the input images, making this workflow a powerful tool for creators looking to convert static art into engaging video content.
API
Use this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// Install (beta)
npm i @comfyorg/sdk
// Run "Grok: Reference to Video" (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
// This workflow, exported in API format (see note below)
const wf = await client.workflows.fromFile("api_grok_reference_to_video_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("6", "image", asset); // LoadImage
const job = await client.run(wf);
await job.getOutputs("4")[0].toFile("output.png"); // SaveVideoThe SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
