A plugin for OBS Studio that allows you to replace the background in portrait images and video, as well as enhance low-light scenes.
Check out the latest releases for downloads and install instructions.
On Ubuntu, there are two ways to install OBS and you have to use the corresponding method to install this plugin.
- If you installed OBS via the official PPA, download the deb package from the releases page and install it directly.
- If you installed OBS via FlatHub, run the following command:
flatpak install com.obsproject.Studio.Plugin.BackgroundRemoval
On openSUSE, please see docs/BUILDING-OPENSUSE.md.
On other Linux distros, use the FlatHub installation of both OBS and this plugin. If you install OBS in a way other than FlatHub, you have to build this plugin by yourself (see instructions for building below).
This video on YouTube will take you through the major parts of the code and explain them.
- OBS version 28+ (download)
We do not support older versions of OBS since the plugin is using newer APIs.
This plugin is meant to make it easy to replace the background in portrait images and video. It is using a neural network to predict the mask of the portrait and remove the background pixels. It's easily composable with other OBS plugins to replace the background with e.g. an image or a transparent color.

GPU support:
- Currently on Windows we support DirectML, which should reduce CPU usage by 95% and effectively use the systems accelerators (GPUs if available).
- On Mac we support CoreML for acceleration, which is available on M1 and M2 (not Intel, sorry).
- CUDA is supported in this plugin through TensorRT, however it is supported only on Linux.
- The goal of this plugin is to be available for everyone on every system, even if they don't own a GPU.
Number of CPU threads is controllable through the UI settings. A 2-thread setting works best.

Some more information about how I built it: https://www.morethantechnical.com/2021/04/15/obs-plugin-for-portrait-background-removal-with-onnx-sinet-model/
The plugin was built and tested on Mac OSX, Windows and Ubuntu Linux. Help is appreciated in building on other OSs and packages.
The building pipelines in CI take care of the heavy lifting. Use them in order to build the plugin locally. Note that due to the fact we're building and packaging OpenCV and ONNX Runtime the build times are quite long.
Start by cloning this repo to a directory of your choice.
Using the CI pipeline scripts, locally you would just call the zsh script.
$ ./.github/scripts/build-macos.zsh -c Release -t macos-x86_64The above script should succeed and the plugin files will reside in the ./release folder off of the root. Copy the files to the OBS directory e.g. /Applications/OBS.app/Contents/.
To get .pkg installer file, run
$ ./.github/scripts/package-macos.zsh -c Release -t macos-x86_64(Note that maybe the outputs in the e.g. build_x86_64 will be in the Release folder and not the install folder like pakage-macos.zsh expects, so you will need to rename the folder from build_x86_64/Release to build_x86_64/install)
Use the CI scripts again
$ ./.github/scripts/build-linux.shThe community maintains AUR packages: https://aur.archlinux.org/packages/obs-backgroundremoval
The plugin is available on FlatHub: https://github.com/flathub/com.obsproject.Studio.Plugin.BackgroundRemoval
$ flatpak install com.obsproject.Studio.Plugin.BackgroundRemovalUse the CI scripts again, for example:
> .github/scripts/Build-Windows.ps1 -Target x64 -CMakeGenerator "Visual Studio 17 2022"The build should exist in the ./release folder off the root. You can manually install the files in the OBS directory.
