I'm a bit late to the discussion, so apologies if you all already discussed this, but are there not multiple software packages available that can chroma key out the background of a human subject even without a green screen? Hell, even videoconferencing apps can do it realtime now. And isn't the objective of passthrough in SLR to almost always key out just the background and allow users to experience the human actors in their room?? So then why not just run videos through keying software first, embed the key layer into the video file, and then the passthrough toggle in SLR can toggle it on or off? Then rather than having all these sliders to fiddle with, you just toggle ON/OFF, and then maybe there is an edge width and strength sliders, like in the Touchly app. This seems totally possible, and if SLR was the first to start doing this post-processing step, rather than the studios themselves, then it would give users an incentive to use SLR over other services.
I've been a long-time passthrough enthusiast, and while the initial integration was cool, and fun to play with, it already seems majorly outdated. Its too much work for the user to dial in a decent setting every time, and it feels time to integrate a proper passthrough toggle that ensures that you are viewing a clean and professionally done video effect.
