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 este workflow a partir do código
Todo workflow Comfy é um grafo JSON. O payload abaixo é este workflow, exatamente como o ComfyUI executa — obtenha-o pela URL, mantenha-o no controle de versão ou carregue-o no ComfyUI e execute nó por nó.
Execute a partir de TypeScript ou Python com o Comfy SDK. O mesmo código serve para o Comfy Cloud ou um ComfyUI hospedado por você — apenas a URL base muda.
// 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");O SDK utiliza um workflow no formato API: abra este workflow no ComfyUI e use Arquivo → Exportar Workflow (API).
O acesso à API do Comfy Cloud requer um plano com chave de API.
