This ComfyUI template turns a single still image into a short, cinematic video using MiniMax H3 Max. The core path wires LoadImage and your prompt (PrimitiveStringMultiline) into MinimaxHailuo03ContextIRNode to package parameters like aspect ratio, duration, and guidance, then drives MinimaxHailuo03FirstLastFrameNode for image-to-video generation with first/last frame consistency. That first/last frame constraint helps preserve the source image’s composition and visual identity from the opening to the closing frame. The final clip is written with SaveVideo, while SaveText can log run metadata for reproducibility.
Two optional stages are provided and start off: a Prompt Enhancer path and a 2K upscale path. ComfySwitchNode routes either your base prompt or an enhanced prompt (if you choose to use it) into the core generator. For higher resolution delivery, the MinimaxHailuo03RegenerateNode can request a 2K version from a 768p base. A PrimitiveBoolean in the Feature Flags group controls this. Important: the 2K upscale only accepts a 768p source; generate the base at 768p before enabling Upscale to 2K, otherwise the upscale path will be skipped or fail.
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.
