Zoom app launching with giant face on Mac

See if this works with Zoom:

Use Center Stage to keep you centered in the camera frame - Apple Support

The article suggests this works with other video apps, not just FaceTime. Look for the FaceTime icon in the menubar when Zoom opens.

The problem is because the camera is automatically opening in portrait and not landscape mode, and then it's cropping so you don't have the black bars on either side. The only way I have found to change the camera to landscape is to open zoom, then also open facetime which detects that you are on a computer and automatically changes the camera to landscape for both apps. I have not found any way to change the camera settings to default to landscape, and so far I have had to do this every time I use zoom.

In zoom you can also open video settings and check "original ratio" so at least when you open zoom it looks like you're using a phone and not just weirdly zooming in on your face.

It's not Center Stage, because the MacBook Neo does not offer that feature.

Center Stage system requirements

Have you tried ticking the HD box in Zoom's video settings? With some cameras, that makes a difference (not sure about the Neo).

Have you tried in Zoom, Window>Switch to portrait/landscape view? The shortcut is command-L.
