This ComfyUI tutorial workflow turns a written prompt (and optionally a reference image) into a short, cinematic video using Google’s Gemini Omni 1.1 Flash via the GeminiVideoOmniV2 node. The node handles the API call to Gemini, then returns a generated clip and, when enabled, an accompanying audio track. You get direct control over aspect ratio and resolution so your outputs are ready for social, product pages, or widescreen edits.
Technically, GeminiVideoOmniV2 is the generator: you provide the prompt and any reference image, set visual parameters, and adjust keyframe interpolation to smooth motion and maintain subject continuity between beats. The SaveVideo node then encodes the frames (and audio, if present) to a file. Because the graph is compact—GeminiVideoOmniV2 feeding into SaveVideo—you can iterate quickly: tweak the prompt, adjust aspect ratio or interpolation strength, re-queue, and compare results for fast creative refinement.
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 this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");The 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.
