ComfyUI LTX-2.3 Video Outpainting

Github

This is a lightweight ComfyUI workflow meant to quickly expand the viewport of a video and a minimum of fuss. Just load your video and select the new output area.

Custom Node Dependencies

I try to keep the external dependencies to a minimum, but there are a few required packages for this workflow to support the core functionality.

ComfyUI-LTXVideo

• Search LTXVideo in ComfyUI Manager.

• Provides the 🅛🅣🅧 Add Video IC-LoRA Guide node required to use the outpainting lora.

comfy-mtb

• Search mtb in ComfyUI Manager.

• Provides the Color Correct (mtb) node.

• Only required if you need the gamma correction feature of this workflow.

• Gamma correction can be used to temporarily brighten dark input video to help the Lora correctly identify which areas to paint. Note about this from the Lora developer.

KJNodes

• Search kjnodes in ComfyUI Manager.

• Provides get/set nodes and LTX2 Sampling Preview Override for sampler previews.

Wan VACE Prep

• v1.0.19 or higher required

• Search Wan VACE Prep in ComfyUI Manager

• Provides the 🪐 Video Outpaint node.

• ComfyUI Nodes 2.0 : The Video Outpaint node has not been well tested under ComfyUI's Nodes 2.0 renderer and may or may not work correctly with it. No effort will be spent to ensure Nodes 2.0 compatibility or stability until Comfy publishes developer documentation for Nodes 2.0.
