Does what it says on the tin, but honestly I find the "uncorrected" video more comfortable to watch.
I think it's just that naturally nobody is keeping 100% eye contact ( except maybe like TV news reporter ), it feels like an interrogation.
This is what I realized is uncomfortable about camera on group meetings in teams - I can't mute other people's video, and so it feels intensely weird to have a wall of people staring blankly at you.
