OBS AI Matting

What it does

Auto light match

Auto light match adjusts the subject’s exposure and white balance to follow a selected OBS background source or scene.checked 8 Oct 2001

Background modes

Transparent mode supports OBS image, video, or color sources behind the camera, and a built-in mode blurs the background.checked 8 Oct 2001

Compatibility caveat

The README says manual installations must be rebuilt after ONNX Runtime upgrades or the filter may stop loading in OBS.checked 8 Oct 2001

Controls

Per-filter controls include blur strength, brightness and gamma, matte hardness, and quality settings of 384, 512, or 720.checked 8 Oct 2001

CPU fallback

If CUDA is unavailable or fails to initialize, the filter falls back to CPU; the project recommends a GPU for real-time use.checked 8 Oct 2001

Installation

The README recommends installation through its Arch Linux package and also documents a manual CMake build and install.checked 8 Oct 2001

Licensing

The plugin is released under GPL-2.0, while the separately downloaded RVM model is GPL-3.0.checked 8 Oct 2001

Localization

The interface is available in English and Spanish and follows the OBS language automatically.checked 8 Oct 2001

Matting model

It runs Robust Video Matting through ONNX Runtime and CUDA to produce soft edges and temporally stable cutouts.checked 8 Oct 2001

Model download

The roughly 107 MB RVM model is required but not bundled and must be downloaded separately.checked 8 Oct 2001

Purpose

The open-source OBS Studio filter removes, blurs, or replaces webcam backgrounds in real time using AI video matting on the GPU.checked 8 Oct 2001
