The LTX-2 Pose to Video workflow is designed to transform pose guidance into high-quality video content with synchronized audio and video generation. Utilizing the LTX-2 model from Lightricks, this workflow offers precise control over pose and expressive motion, making it ideal for creating dynamic video content. The workflow integrates various nodes such as GetVideoComponents, PreviewImage, and SaveVideo, which help in breaking down the video into components, previewing frames, and saving the final output, respectively. A key feature of this workflow is its use of the comfyui_controlnet_aux custom nodes, which enhance the precision of pose control and motion expression.
Technically, the workflow begins with video and image preprocessing using nodes like LoadVideo and ResizeImageMaskNode. It then employs the DWPreprocessor for refining video settings, ensuring optimal frame count and resolution. The workflow is designed to handle resolutions up to 1920x1088, though it defaults to 720p for efficiency. The frame count must be divisible by 8 plus 1, ensuring smooth transitions and synchronization. This workflow is particularly useful for creators seeking to produce videos with detailed motion and synchronized audio, leveraging the power of the LTX-2 model to achieve professional-grade results.
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 "LTX-2 Pose to Video" (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
// This workflow, exported in API format (see note below)
const wf = await client.workflows.fromFile("video_ltx2_pose_to_video_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("160", "image", asset); // LoadImage
const job = await client.run(wf);
await job.getOutputs("175")[0].toFile("output.png"); // SaveVideoThe 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.
