Recently, I found a tutorial on youtube, explaining how to replace video backgounds with a green picture. The example video was flat with a guy talking in front of a static background, so not much movement. Basically, the guy was streaming the video from OBS into Zoom, let Zoom replace the background in real time and then recorded the Zoom video feed with the new green background in a second instance of OBS. It's quite simple to set this up and I tried a few VR videos (not the recording part). However, it did not work out very well. First of all, the background replacement was different in the right and left parts of the VR video. And while it may have looked great for a moment, most of the time body parts were disappearing and reappearing.
