gxalpha submitted a new resource:

macOS Background Removal - Background removal plugin using macOS' system APIs

This plugin provides a filter to remove a persons background using macOS' built-in Vision API.

The filter can be found in the filters window under "Effect Filters". This means that it can be used on any type of source, not just Video Capture Devices.

If you have support questions, please ask in the #plugins-and-tools channel on the OBS Discord server. Feel free to ping me there (gxalpha#3486).

Thank You so much! However it went through the install process, but doesn't show up anywhere. intel mac OS Ventura. Also, I'm not on discord. Sorry. Looking forward to your updates.

It was easy to install and a simple interface. It's as good as any virtual green screen I've ever tried. Not sure if the issues can be fixed. With this technology you're dealing with many configurations mostly at home that may need the proper distance, lighting and the right colored cloths to fix these issues. Kudos for taking the time to develop it for the Mac, so I look forward to trying any upgrades you might make. Thanks.

Thank you for the largely positive feedback!
Which kinds of issues did you run into? If it's with the segmentation not working perfectly it may be possible that it's not fixable on my side, but I'd be happy to look into them.

Thank You for quickly attending to my post. I don't know the jargon, but I believe it is the segmentation. It gets worse when you move. However, like I had mentioned before I don't think I've ever used an app that could do it perfectly. I am in a small space that I'm not sure if I could ever get the right lighting for this. When I recorded a video a few years ago I had access to some household lights. After recording with a physical green screen I edited it out in iMovie. It worked out well, but trying to do things live I haven't had the best success. I'll keep trying different configurations. It's a nice plugin though. Thanks so much for your efforts.

sebastianbeckmann updated macOS Background Removal with a new update entry:

Lower mask delay

Updated the mask to have a much lower delay than before. There still is some delay (a bit of which is unfortunately unavoidable), but is better than before.

In theory the filter might now have a higher system resource usage than with version 0.1.0. I did not find a noticeable difference in my testing, but please write a comment in case this poses a problem on your system.

Hi. Thank you for the great plugin! I wonder if it makes sense to make "mask delay" configurable in the plugin settings. I would love to try even smaller values for it.

I've installed the plugin, but don't see it in OBS filter effects. Have opened and closed OBS. Attaching current log file.

@oracle22 could you check if the plugin is installed in "~/Library/Application Support/obs-studio/plugins"? If not, is there one in "/Library/Application Support/obs-studio/plugins"? (The tilde (~) makes a difference)

Lower Mask Delay​

The MacOS Background Removal Plug-in has a small mask delay. Using a combination of Plug-ins, the mask delay can be lowered even more.

Required OBS Plugins​

First, install these plug-ins

Create a Scene​

After installing the required plug-ins create a new scene. An example scene name "BGR_Scene".

Add Sources to the Scene​

  1. Add a Video Capture Device Source (Set to not visible)
  2. Add a Source Clone(Set to not visible)
    • Settings: Clone type = Source
      • Clone = Video Capture Device
  3. Add a Source Clone
    • Settings: Clone type = Source
      • Clone = Video Capture Device
    • The second Source Clone will be named "Source Clone 2" by default
A picture of Scene and Source names

Add Filters​

  1. Select “Source Clone”
    • Add a “macOS Background Removal” filter
      • Settings: Threshold = .8, Quality= Balanced
  2. Select “Source Clone 2”
    • Add a “Render Delay” filter
      • Settings: Delay = 90ms
    • Add a "Advanced Mask” filter
      • Settings:
        • Mask Effect = Alpha Mask
        • Mask Type = Source
        • Source: Source Clone
NOTE: This guide was tested on a MacBook Pro M1. Settings may vary on a different Mac.
