There's what appears to be a TV in the background that has picture shifts/cuts, and there are a couple people moving around back there, so it's most likely a real background beyond the depth of field somewhere. Shot in someone's house or whatever space they're in... Looks like some funky chandelier in a dining room, someone on a couch, then further back, a kitchen? Who knows.

Haha! I guess I should have thought more about what I was writing.

My question would be how do you blur out the depth of field like that? I know how to film someone on a green screen, and put them at the center with a background of moving people, what I don't have an idea on how to achieve is a blurred background that makes it appear as though the focus is on the individual and the whats behind the subject is blurred - if this is the right way to express it.

All you need is a short depth of field.
Focus on the person, and the rest is some distance behind, and not in focus.
Focus in on the background, and you would blur out the foreground.

"Portrait mode" on an iPhone does that automatically.

Everything you might want to know about Depth of Field is here.

What wonderspark was trying to tell you is that you don't need to shoot with a green screen to do this. The clip you referenced may very well be one actual recording, using a very shallow depth of field.

If you do want to do this with green screen and put a separate background behind your subject, experiment with the various blur filters to get the desired effect for your background clip.

Just use a fast lens, opened up to lowest f-stop, and put focus ring all the way forward to closest range. Then place subject in that focused space, and adjust ISO and shutter to properly expose for background, maybe just a bit darkened, ideally. Lastly, set up subject lights dim or bright enough to fill same exposure setting, so it's all balanced. Keep subject just a bit brighter than background, in my opinion.
