How did you manage to get 16:9 format from a stereoscopic capture of one eye? In my case, the stereoscopic mirror has two round screens, basically, as if I was looking through the lenses. If I try to capture the whole shape of one eye, it won’t be in a shape of 16:9 but like a square. I bought the game through game pass, so it’s Microsoft store, not the Steam. Maybe you are playing in SteamVR (are you?), it’s prolly different for you. So I have to limit myself to the G2 portal recording app, I don’t know any other way to get the 16:9 format at this point.
