Welcome to CNN World Headquarters here
in Atlanta, Georgia. This is Studio G,
where I host CNN World Sport. We've got
you covered. I'm Koi Wire. This is World
Sport. 30 minutes of moments that make
jaws drop and hearts race. Pretty
snazzy, right? Well, if you haven't
noticed, there's a secret. I'm actually
standing in a TV studio that's green.
Everything around me, the walls, the
lights, the motion, even the screens are
created by a powerful computer system
running something called Unreal Engine.
The same kind of technology used to make
video games. Listen, before I ever step
on set, a team designs a digital sports
world. Kind of like creating a level of
a video game. They design backgrounds,
lighting, video screens, and animations.
All of that lives inside the computer.
The cameras filming me don't just record
video. They also send information to the
computer where the camera is, how it
moves, when it zooms or pans. So when
the camera moves, the virtual background
moves with it, making it feel real.
That's why it looks like I'm actually
inside the scene. And behind the scenes,
operators use real buttons, not
keyboards, to control everything. One
button might change the background,
switch the lighting, bring up a graphic,
or move us to an entirely new location
in this enormous room. It all happens
live while I'm talking to you. My job,
focus on the story. The computer is
updating the scene. The cameras and
graphics are staying perfectly in sync.
If everything works out right, you don't
even notice the technology, just the
story. So, my job is fairly easy
compared to the rest of my team. And the
main thing is I have to remember never
wear green.
Anything green will display whatever the
computer is putting out. So if I'm
wearing a green suit or a shirt or
bodysuit, this is what we get. Pretty
cool. Oh man.
Woo. I'm the head of my class. So when
I'm long and gone someday and some of
you come to take my job, remember, never
wear green. Speaking of long and gone,
see you.
