So let's go back into the video realm for a moment. We showed you earlier some demos about synchronizing video together. I want to bring out in a moment Sylvain Paris, who's going to show you really some groundbreaking work for real-time manipulating and editing of video. Sylvain, why don't you come out and show us video meshes? Sylvain Paris. Hi, everyone. I'm going to show you a Sneak about video editing. Here I have a small piece of footage with my friend walking across the hall. I can go back and forth, and I want to edit it. Usually when I do video editing, it's fairly 2D. Today I would like to show you something that will do it much more 3D. To do that, first, for instance we have added some structure. We added these triangles, and the triangles follow what's going on in the scene. Also I have done some rotoscoping beforehand, because you don't want to see me doing that, but I've rotoscoped the main character as he walks back and forth. So let's change it a bit. Go back to the beginning. The first thing that I'm going to do is to show I have specified the ground plane we see here. I can help the software by doing some modeling. I'm going to show where the columns are--for instance, here, here, here, and the rest. Now I've shown everything where it is 3D, and I'm going to do some computation. It's going to be crunch a few numbers, and while it's doing that, I have to tell you I'm running everything from a laptop. Sometimes it's a bit slow. If we had a video workstation, everything would be real time. Let's say that I will show you some effects in slow motion so you see a bit better. It is computing. It soon will be done, and I will show you a bit of what we can do once we have analyzed the structures of the columns and the ground. What he's done is he's told the video of the different 3D shapes within the video. Now the program knows that this isn't just a static image. It actually knows that those are 3D objects within the video, and now he'll be able to start editing and making the video really be aware that there's a three dimensional in it. To go back here, let me remove this information. Remember, I never moved the camera in the original footage, but now I know about the 3D so I can do some cool effects. For instance, I can go inside the scene. >>Wow. >>I can look around. Of course, there are some places I don't have information, but-- Dude, dude, seriously, that's like Bladerunner. Remember? They go in the photograph and the snakecharmer woman, and they see the scale on her. Do you remember? No? You didn't even see it? No. >>What a loser. You have to see it because that's it. This is so cool. Keep going. I can add my character back. I'm here. So now I have my character--let me see. I can do some things. I can move this character around. Because I know it is 3D, I know when I go far away, I become small. When I come back, he becomes the right size. >>That's insane. That is seriously insane. I can also hide it behind the column, because I know there is a column here. I can put it here and different places. Let's say I like it here. >>Dude. You can make a lot of money from this program. I'm serious. How does that work? Who's going to make the money from this thing? I don't know. >>Well, I think we've got a good idea. >>What? That's incredible. Of course, I can do the same thing. I can move the camera while I play the video. Here it is a bit slow mo, but it would be fast if I had a full work station. I cam move back and forth and have another one coming it. Right? And remember, I never moved the camera at the beginning. It was all on the tripod. That's ridiculous. Wow. That is sick. >>It's ridiculous. If you liked that, you're going to like this one too. Because I know it is 3D, I can change other parameters like depth of field, for instance. Let me go there. I can change the picture of my camera. For instance-- Wow. I can move the focus at a different place. I need to click here first. For instance, I can focus on the background and come back. Wow. I can l do it while I play, so let me go a bit forward where things are a bit more interesting. I can play, and I'm going to see my other copy, which is going to appear soon--here. I can click here, and as it plays, I refocus, go back to the background, come back here-- all in real time. Wow. One last thing. Let me come back here. If you like videos, you probably like Alfred Hitchcock. He had a very nice effect that he introduced to the community, which was the vertigo effect. Let me show you a little bit of that. It's very hard to do, because we have to move the camera backward, and change the focal length at the same time. Now we can all do it in software. As the character moves, the camera is moving backward as we change the focal length to have this impression where the scene collapses into itself the very same way that Alfred Hitchcock was proposing. That's it. That's real time 3D editing in video. Thank you very much. Thank you, Sylvain. >>Amazing. Pretty mind-blowing, isn't it? That's incredible. I mean, that's incredible. He did all that in like 3 minutes. That is the kind of technology that we're working on. It's just amazing, isn't it? Seriously. I'm totally blown away. I seriously am. He can go home to his family. Yeah. Now he can go home and spend time with his family. That's right. He earned it.
