The LTXV Image to Video workflow in ComfyUI is designed to transform static images into dynamic video sequences. This workflow leverages the LTX-0.9.5 model, which is specifically optimized for generating video content from still images. The process begins by loading necessary models and configurations using nodes like CLIPLoader and CheckpointLoaderSimple. The core transformation occurs through the LTXVImgToVideo node, which applies advanced conditioning and scheduling techniques via the LTXVConditioning and LTXVScheduler nodes. These nodes ensure that the generated video retains high fidelity to the source image while introducing realistic motion and transitions.
Technically, this workflow utilizes a series of nodes to encode text prompts (CLIPTextEncode) and decode visual data (VAEDecode), ensuring that both the visual and conceptual elements of the input image are accurately translated into video form. The inclusion of a custom sampler and KSamplerSelect nodes allows for fine-tuning of the video synthesis process, providing users with control over the aesthetic and motion characteristics of the output. This workflow is particularly useful for artists and content creators looking to animate their static imagery with minimal effort, offering a seamless integration of AI-driven video generation techniques.
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 "LTXV Image 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("ltxv_image_to_video_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("78", "image", asset); // LoadImage
wf.setInput("6", "text", "your prompt here"); // CLIPTextEncode
const job = await client.run(wf);
await job.getOutputs("81")[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.
