Did you see the video? Its weird - with a green screen or chromakey usually the background is whats keyed in - meaning BG is not really there, just the screen behind the subject.
Just the opposite on the YT video the background remain but Obozo fades out to just barely an outline then re-appears.
Indicating he was videotaped at an earlier time at a some studio??
That round topped brown thing that shows when the CGI data feed
glitches, is a computer construct. A “hanger” for the CGI, if you will.
Any CGI folks here, familiar with some of the newer tools?
One uses the tool to move the hanger around, to place the subject where
you want, in the frame.
