This ComfyUI workflow expands the boundaries of an existing video clip using LTX-2.3 with a dedicated Video Outpainting IC LoRA. It decodes your source video with VHS_LoadVideo, feeds frames into the core LTX-2.3 generation node (the custom node with ID 2e37ecc9-770a-4ac2-972c-e953901f49d3) where the LoRA guides the model to synthesize plausible content beyond the original edges, and then stitches the processed frames back into a video with VHS_VideoCombine. A MarkdownNote in the graph provides quick, in-context guidance.
Technically, the LoRA biases the base LTX-2.3 video diffusion model toward temporal, context-aware extrapolation. Controls like skip_first_frames and frame_count let you trim a long clip and iterate quickly on a representative segment before running the full range. Outpainting direction and amount are set on the LTX processing node (per-side expansion), while LoRA strength determines how assertively new content is invented versus preserved from the original. The result is a coherent, time-consistent extension of your scene—useful for reframing, adding headroom/side room, or conforming videos to new aspect ratios without obvious borders.
API
Usa este flujo de trabajo desde código
Cada flujo de trabajo de Comfy es un grafo JSON. El siguiente payload es este flujo de trabajo, exactamente como lo ejecuta ComfyUI: descárgalo desde la URL, guárdalo en control de versiones o cárgalo en ComfyUI y ejecútalo nodo por nodo.
Ejecuta desde TypeScript o Python con el Comfy SDK. El mismo código funciona en Comfy Cloud o en un ComfyUI propio: solo cambia la URL base.
// 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");El SDK utiliza un flujo de trabajo en formato API: abre este flujo de trabajo en ComfyUI y usa Archivo → Exportar flujo de trabajo (API).
El acceso a la API de Comfy Cloud requiere un plan con clave API.
