not perfect..
Reasons:
1. I don't know how, but most Video meeting Software does it better (Developers here wont have a professional Budget and Team - I am just objective). "Xsplit Vcam" in the free model has better BG removal, but it is limited to 720p and has a very present watermark.
2. with activated BG Removal, my CPU monitor inside OBS raises from 9% to 63% with "calculate mask every" 1 Frame, or 54% with every second frame.
3. Also, my webcam seems to loose FPS if BG Removal is activated.
I use:
LG 920C Webcam with OBS 27.2.1 64-bit.
Unfortunately Audio/Video filter is impossible in the particular case of our plugin, but the effect filter works beautifully. I hope that can be useful for you.
