Webcam preview size changed

Hi There,

My company has been using Zoom to record a series of webinars, and the webcam preview has always been a certain size when we share the screen.

However, my colleague made a recording earlier today and found that the webcam preview in the recording has been reduced to roughly half the size compared to earlier videos. I wanted to know whether Zoom has changed some default setting in how webcams are previewed in meetings, and how I can return the webcam preview to the previous larger size. When I try to resize the preview, it is only changed in my screen, not in the actual recording.

Thank you for your time.
