ComfyUI Wan VACE Video Outpainting

Github

This is a lightweight, (almost) no custom nodes ComfyUI workflow meant to quickly outpaint a video with Wan VACE and a minimum of fuss. Just load your video and select the new output area.

Dependencies

My ComfyUI-Wan-VACE-Prep custom node package, v1.0.16 or later, is required for this workflow. It replaces a large amount of awkward spaghetti workflow math, making this lightweight workflow version possible.

In ComfyUI Manager, search for Wan VACE Prep or just load the workflow and then visit the Missing tab in Manager.

This is a very lightweight package with no dependencies, so it is highly unlikely to break your system, if that is something you worry about.

ComfyUI Nodes 2.0 : The node this workflow relies on has not been tested under ComfyUI's Nodes 2.0 renderer and may or may not work correctly with it. No effort will be spent on ensuring Nodes 2.0 compatibility or stability until Comfy publishes Nodes 2.0 documentation for node developers.

Configuration and Models

You'll need the Wan VACE model to run the workflow. Select one appropriate for your system below. Aim for a model weight that matches what you use for normal Wan video generation. e.g., If you usually use an fp8 Wan model, try the fp8 VACE model.
