MatAnyone2 Video Matting for ComfyUI

Smoke Test Registry License Python Nodes

Interactive video matting inside ComfyUI with a built-in SAM point editor and MatAnyone2 propagation. Queue once to open the editor on the first frame, queue again to render a clean foreground pass, alpha matte, and preview composite across the full clip.

Features

• Two-pass interactive workflow: fast first queue to open the editor, full second queue to render the matte.
• Built-in SAM overlay: positive and negative point editing happens directly in ComfyUI.
• Multi-target masking: create and compare multiple mask targets before committing.
• Pinned vendor snapshots: the package ships known-good MatAnyone2 and Segment Anything source snapshots in vendor/.
• Bundled starter clip: the sample workflow ships with a tiny demo video that install.py copies into ComfyUI/input/.
• Manager-ready packaging: requirements.txt, install.py, workflow example, and registry metadata are all included.

Included Workflows

Basic Demo

workflows/matanyone2_demo.json is a ready-to-run example that wires video loading, frame selection, the interactive editor, and final matte export.

It defaults to the bundled matanyone2-demo-input.mp4 starter clip that install.py copies into ComfyUI/input/. Swap the Load Video node to your own footage whenever you are ready.

LoadVideo -> SliceFrames -> SelectFrame -> Interactive SAM -> Matte -> SaveVideo x3

How to use it:

1. Drag workflows/matanyone2_demo.json onto the ComfyUI canvas.
2. Queue once on the bundled starter clip, or replace Load Video with your own clip first.
3. Queue once to open the editor on the first frame.
4. Left-click for foreground points and right-click for background points.
5. Click Apply in the editor.
6. Queue again to render the full matte outputs.
