This. Just a few days ago I wasted a few hours playing with OBS, CamTwist, and a few other "chroma key capable apps"... all with no luck... Zoom's built in beats them all....

What I really would like to do is have my green screen capabiity regardless of the video conference app (e.g. Facetime, FB, etc)...

I ran into the issue with syphon and Camtwist... and I gave up :)
