Think it works quite well, maybe it would look better if they turned the actual screen green then superimposing the presenters and then replacing the green with a now seamless background, then when they cut to a distance shot, the actual background changes in sync, would that work?
Maybe they don’t want it too realistic otherwise it gives the wrong impression.
That sounds like a lot of faff just to get a half decent two shot, and I highly doubt they need the hassle in a live environment of needing to change the output of the screens exactly in sync with the vision mixer every time they cut to a wide shot. Plus green screen hardly ever works that successfully when the green backdrop is on a screen rather than being a physical, properly lit backdrop.
So I don’t think we’ll be seeing this two shot “solution” in use.
I honestly don’t see why there’s suddenly this effort to make everyone look like they’re sat next to each other on so many shows anyway. Social distancing is a part of life, and will be for the short term future. I jusy don’t see the benefit in going to trouble using camera trickery to make hosts on TV shows look like they’re “back to normal” when we all know they’re 2m away from each other and that’s looked fine for the last 4 months or so.
