Ask HN: Video call software that saves video on disk in source quality?

It's kind of obvious stuff when you do a remote interview to be published - to talk in real time, but later assemble video "in post" based on recordings (made locally on both ends) that won't suffer from dropouts and low bitrate.

Yet, a cursory search did not reveal anything like that. Nobody thought of this already? You could do this in a roundabout way (OBS and Skype/Zoom/whatever in parallel), yet this is begging for a nice package.
