This ComfyUI workflow turns a plain-text prompt into a fully produced video with synchronized dialogue, sound effects, and music using the HappyHorse 1.1 model. The HappyHorseTextToVideoApi node sends your prompt and settings to the HappyHorse service, which generates a single video file with the audio track baked in. The SaveVideo node then writes that returned video to disk at your chosen path, so you end up with one ready-to-share file.
Technically, the workflow is lean and focused: HappyHorseTextToVideoApi handles all generation remotely (visuals and audio together) and outputs a unified video object. There is no intermediate frame assembly or separate audio pipeline to manage in ComfyUI. This makes it ideal for rapid iteration on short episodic content, product spots, and cutscenes where timing between visuals and sound is critical but you want to avoid multi-node complexity. By structuring your prompt with clear scene descriptions, quoted dialogue, and simple sound/music cues, you can guide HappyHorse 1.1 to produce coherent, timed sequences that SaveVideo preserves as a single file.
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.
