How to prepare for a video call screening?

This might be a dumb and simple question but anxiety and all that fun stuff, but is how can I prepare for a video call screening? Like with phone screening (which I thought it was gonna be) I could have stuff with me and kinda pace/fidget as I talk, but when they sent the time confirmation, they mentioned it being a video conference, so a little freaked. Like does that also mean there's gonna be a group in the call, like I'm sure it's not gonna be completely different but I just want to know what to expect and prepare for it. I still have a few days so I shouldn't be freaking tf out yet, but I figured overreact now and get the most info on what I might expect?
