 No, it's working Two years ago, we started a movie project in Karlsruhe with which had the very important target to put zombies into blunder No, I think I can't I just use this one is it's okay For two years ago, we started a movie project in Karlsruhe, which had the very important target of putting Zombies into blunder as you can see at the picture this involves a lot of screen screen Poorly lit and with a lot of damages in the background hard-working scientists in forward and foreground and several zombies in the background not to mention the wide-angle lens Which is also quite necessary for that your task We had a very Same interesting story which a background which the story had this crazy idea that this That the room will get smaller and the actors will grow and it was really really big effort It was nine nine hundred nineteen thousand effect frames. We had to we had to process with One and a half person and not much time. Well, we worked it out And this involved developing a new key and new solution. We tried all the solutions on the market right there on the open source market to be exact and Nothing worked really are really out even the current keying solutions in blender don't really work I can show you why there's a problem and how we solved it The main point is there are certain parts of a green screen which are pretty easy to be done and some don't I just show it right here. The interesting part is the hair part and the really interesting part is the hair part Where the green screen has defects? So we just managed to get it done. You can see the hair parts are pretty nice You can see if the transparent areas everything is fine and dandy Normally, you get rather big checklist what you have to do, right? I don't mention all the details The very important point is we fuck them all up But we handled it efficiently how you can how you can see down down there This is a picture where you can even see a really really bad problem when the actor is walking out of the green screen You it's it's rather funny So we built the blender uber keer We build it from scratch. We followed the image keer image-based here, you know probably from nuke We automated it everything with chorus reflection mats and what not and Made the whole solution a lot more automatic In one minute how it works, you maybe know how a difference keer works It use a maximum we use some average subtracting. We roughly cut out the mac actors Rebuild the background a youth up and using an impending node, which is new to blender scale the male build core made automatically tweak the automatic and so on and so on and Very important if you got actors on the run use a luma keer which also works in the process and denoise material Or you'll get problems with the shadows The very basic idea is to build with this picture from ideas of steel You can see on the left side the cutout background How it's worked out and on the right to see it's just a one-click solution works So to composite the whole thing we did something really crazy We use cycles as a compositor which works really great if you will get use this keying process You get the diffuse mat, which can work in cycles if you use Billboards frames and use them as emission planes And you can get pictures like these out of it if you want to render all this ten minutes per frame is Is Obviously necessary you have to use some other project we use point and Distributed it to several machines out there in the internet use ten of them and a generic Render script to pull all the dependencies and did all the dance and put it back fun fact You can do it with pretty cheap cars it's It's rather affordable and well 64 bit is a quite a big boost if you have any questions, please ask 15 seconds Yes, yes
