May 31, 2021
you know, the

green

screen

and the blue

screen

, you know, it becomes the lost planet, covered, desert jump background, what happens when the imaginary planet is already there the moment you get in the middle of the volume, you're just there , the volume is the epic sounding name for the combination of high resolution LED panels imagine impressive huge television screens enveloping a stage, the design of the physical stage matches the panels and 3D models placed in an environment in the same way as they do it in a video game and then it can respond to camera movement to simulate the real world disney plus the mandalorian a star wars live action tv show used this technique my name is charmaine chan and i am a lead composer at industrial ida magic It's physically confusing being on this set oh, absolutely.

I mean it's like you're filming all day, let's say the exact same scene and like you're in that place, it doesn't feel like it's fake, it just feels like a fake. extension of a normal scenario. I know you have to be careful because there are times when people don't see where the end of the stage is and where the LEDs are. You have situations like Wiley Coyote and Roadrunner where someone runs into the wall or something. Yes, we definitely make sure. that no one is running on that stage for that reason charmaine is credited as part of the brain bar the group of visual effects artists who operated this system one could fit models like a rock or a spaceship on the panels while another could modify animations Live like a burning fire, Charmaine would often adjust the color, it was funny because it was a lot like the days when there were phone fundraisers like on PBS, it was just groups of people with phones ready to go, but instead of telephones we had computers. on our walks while Mandalorian visual effects supervisor Ian Milham tweeted that the set crew and the brain stick operating the panels allowed them to radically change the environments in just a few hours or beyond the set when launched into hyperspace.

the technology that s replacing the green screen...

My normal work life is largely based behind a computer in a dark room somewhere in the corner now I'm there with the boss with the prop designers with the set designers most of the people we would never see because we are in the process Post-production was very fast-paced, but scenarios like this were not only fun for Charmaine, but helped eliminate creative obstacles as a composer. We're the ones who take all the renders, we take all the cg elements and we put them together to make it look like one perfectly integrated photo, so think of It's like advanced Photoshop, but to deal with moving images, Charmaine worked on this scene in the last Jedi, we get this footage of Kylo in front of a

green

screen.

If you're lucky, this green screen will be lit evenly seamlessly and it's a piece of cake, that's never the scenario, spending time almost frame by frame making sure we can remove that green screen so we can put Kylo on top of it. Removing a green screen is still quite difficult for someone who doesn't work with green. characters, Yoda's green, removing a solid color or keying can look good, but you still need detailed work. Watch how these thin branches just disappear. The perspective of the background also does not change naturally, that must be designed into the final composite, removing the green screen and projecting. or playing the image behind the actors gets you closer but not quite, you can get details in an illusion of depth and better light instead of a green screen spilling onto the actor you get a blue sky and a red desert that really illuminates them, in that basic technique it has worked. everything from 2001 to oblivion, but you missed the proper perspective shift or parallax in the background as it's just a video played on a screen, volume addresses some of those issues, you can also adjust the light and objects on the fly and the reflections actually work because they are reflecting the other screens instead of a green screen, which was especially important for Mando, the main character of the show, all of his armor was reflective from head to toe, whether it was his shoulder pad or his helmet, it was like you couldn't help but see things reflected.

So by creating this volume where we could literally close everything in a giant circle and have an environment on all these screens, we got exactly what we wanted out of his helmet, the brain bar could focus on the details that made the final product so transparent as possible, which was still a lot of work, I would go in and whether it was a rock or a barrel or something, I would try to color correct it to match what was on the set, but where the color correction was most important was when We're dealing with the biggest parts of the set, so whether it's the dirt on the ground versus the dirt in our digital scene and the lighting of the scene affected the dirt on the ground, so we'd have to like it because we had a blue sky. and suddenly now there is all this blue on this rock, we would have to correct the color of the ground and the rock so that they also had as much blue as the blue we just entered before they started shooting.
I would have five to ten minutes to get everything. aligned and ready to go. I imagine there are some creative advancements this makes possible for your work. What would those be with this

technology

? I'll be honest, I wouldn't be mad if I never had to do a green screen intro. or extraction anymore now I can be a person doing the shot and I can basically help finish a shot on camera, it just makes the filming process more cohesive and this puts us right next to everyone else who creates these shows. or movies, it was great to talk to Charmaine and learn a little about his work and some of the amazing things he has worked on.
This video is actually from a sponsor which is Verizon. They just activated 5G throughout the country, so with 5G throughout the country and more. and in more cities you get unprecedented performance an ultra wideband 5g it's really fast the fastest 5g in the world you can download an album in a few seconds it won't just change your phone it will change everything i guess many creative breakthroughs will also emerge so this It's the 5G America has been waiting for, and it's only from Verizon. Verizon has no direct impact on our editorial, but your support makes videos like this possible.
