3
🎥 Upload Your Video

You load up your video and roughly draw or select the object you want to vanish, like circling someone in the background.

4
🔍 Smart Outline Finder

The tool automatically expands your rough mark into a perfect outline that follows the object through every frame.

5
🧹 Erase the Object

With one click, it seamlessly fills in the empty spot with realistic background, making the object disappear like magic.

6
🌅 Blend New Background

You drop in a new scenic backdrop, and it perfectly layers your edited video onto it for a fresh look.

What is ComfyUI-TP-OmnimatteZero?

This Python-based ComfyUI extension adds github comfyui nodes to run LTX's OmnimatteZero model natively, enabling video object removal and matting workflows. Drop in a video and rough object mask, and it auto-generates precise total masks via self-attention extraction, inpaints clean backgrounds, then recomposes objects onto new scenes—all within familiar ComfyUI interfaces. Solves the hassle of porting advanced video decomposition tools like runway nodes or animation nodes github into ComfyUI without custom scripts.

Why is it gaining traction?

Stands out with one-click install via ComfyUI Manager, included workflows, and auto model downloads, skipping manual Hugging Face fiddling. VRAM savers like VAE tiling, slicing, and CPU offload make it runnable on RTX 40/50-series GPUs, unlike raw Diffusers setups that choke on long clips. Developers dig the chain: mask gen, object removal, composition nodes that output ready-to-use videos, fitting seamlessly with other comfyui nodes.

Who should use this?

ComfyUI power users building video pipelines—AI artists masking actors from footage, VFX hobbyists swapping backgrounds, or animation nodes github tinkerers prototyping rune nodes-style effects. Ideal for those chaining with geometry nodes github or bimorph nodes github in runcomfy nodes workflows, skipping desktop apps like Runway.

Verdict

Early days with 18 stars and 1.0% credibility score—docs are basic README screenshots, no tests—but solid for ComfyUI video matting if you're on tested NVIDIA hardware. Grab it via Manager if object removal fits your stack; otherwise, watch for maturity.
