Enable virtual background

I have a therapy group at 4pm and want a neutral office background. Turn on a virtual background for my video, select a plain light-gray office image, and verify my video preview looks natural with no ghosting before the session starts.

Before I enable a virtual background for the parent-teacher meeting, make the background look professional and avoid distracting artifacts. Choose a plain office image, reduce background blur if it causes haloing, check that my headset shadow isn't cut off, and tell me if my current lighting will cause noticeable ghosting.

I enabled a virtual background and my left shoulder is flickering and my hair has a halo. I don't know whether to change the image, adjust lighting, or turn off the effect for credibility with parents. What's the likely problem and the quickest fix that keeps it looking professional?

Across teaching weeks I spend ten minutes before every parent session tweaking lighting and backgrounds so I don't look unprofessional. What habits or prep changes will reduce setup time and produce consistent, acceptable video without fiddling right before each call?
