This ComfyUI workflow turns a single still image into an audio‑reactive video using the LTX‑Video 2.3 model enhanced with the Audio‑Reactive LoRA. You provide one image via LoadImage and an audio track via LoadAudio; a GeminiNode in the Create Audio‑Reactive LoRA Prompt group helps craft a clean, descriptive text prompt from your idea (and optionally your image context). That prompt, together with the image and audio, flows into the LTX 2.3 video generator node (dacae91a-7342-43be-a654-227b303c33bc), where the Audio‑Reactive LoRA modulates motion and visual rhythm in response to the soundtrack. You can preview output with PreviewAny and export the final result with SaveVideo.
Technically, the workflow applies the Audio‑Reactive LoRA from https://huggingface.co/100percentrobot/LTX-2.3-Audio-Reactive-LORA at inference time on top of LTX 2.3. The LoRA strength parameter controls how strongly the audio‑driven behavior influences the video: use 1.0–2.0 overall, with 1.4+ for more pronounced reactivity. This design is practical for fast, beat‑aware animations of posters, album art, and social posts: you focus on a concise prompt and good source media, while the LTX node handles frame synthesis and timing, and SaveVideo writes a ready‑to‑share clip.
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.
