Xbox greenscreen

I'm pretty sure this is done with a greenscreen in post production. The person has a video and then records himself on a greenscreen to then add himself into the video as I don't believe the Kinect has a built in feature for this at least I have not seen
anyone use this from the kinect directly.

As an example from googleimages

Even though this is old now, here is an interesting article people may not have seen about this trailer and it's visual effects:

I personally don´t care if the streamer has a greenscreen or not. I watch them for the content they deliver.

the greenscreens not the issue, you missed the whole part about it doing nothing when i hit factory reset.

Could you link one of those videos?

Because I think it's done with a greenscreen and they add themselves into the video later
