How to change (increase) resolution of QT recording?

I want to know how to increase (or change) the video resolution/quality of a Quicktime video recording on Mac. I have OS Catalina 10.15.7. Is there a way to do this? Can someone pls help? thanks.


Your options are limited. Most Mac cameras (except for the 2021 iMacs) are 720p, and the settings offer "High" and "Maximum".

If you're recording the screen, then obviously you get the screen's resolution.
