I've tracked this footage here from art beats with a 3D camera tracker in After FX to create a camera and lighting to then compose the 3D elements into the scene. And I'm going to do that now. We're in chapter 905 AEP. If you want to follow along, you can open up that project. We're going to have a look at a couple of ways of compositing the elements together. First in After Effects and then in Cinema 4D. So I'm going to start by importing my Cinema 4D file into After Effects. And then I'll show you how to do it the other way around.
Bring in After Effects comp into Cinema 4D. So, what we'll do is, we'll double-click down here in the Project panel. And that will open the Import File dialogue box where I can select chapter 9_05.c4d. And that's the file we're going to import into our After Effects project. Now, you'll see it appears here in the project. But in order to bring it into my comp, I need to drag it into the comp. So I'm going to drag it down to the timeline and just release when it's at the top of the timeline.
Now at the moment that looks pretty rampish. Doesn't fit in the tall with the background footage. But that's because it's using the Cinema 4D camera and the Cinema 4D camera doesn't know about this footage. Doesn't know how the footage was shot or what camera angle was used. But the three D camera we made in After effects from the three D camera tracker does. If we go back to our cinema four D file and go into cineware there's an option to use the comp camera.
So we can go to Comp Camera. And immediately, you'll see that our robots jump on top of the building. So they're now reacting to this camera tracker that was created using the 3D camera tracker in After Effects. And if I ran preview it, you'll see that just like magic, I've got my 3D scene stuck to the top of this building. At the moment that's in Software mode, so if I just jump to standard draft you'll get a better idea of how that's look without the (UNKNOWN) And you'll see that I've successfully, just with a couple of clicks really, composited my 3-D elements into this scene.
As if they were there when it was shot. Now there's a lot left to do. We've got to do some materials work, some lighting and add some various After Effects. But you'll see how easy it is just to get footage to sit in there with the original footage as if it had always been there. Once we add some shadows and lighting to this it will really bring the scene alive. Now, the only thing is, you'll notice that the duration isn't long enough. So, what we're going to do is, we're going to quickly jump to Cinema 4D, and just adjust the settings to make this longer so it fits the comp.
Now, very important, if you have a look at my composition settings, you'll notice that I've got a frame rate of 15 frames a second here and 316 frames. If I select this, Cinema 4D file and hit Cmd+D or Ctrl+E on Windows, it will open the scene, in Cinema 4D Lite. And you can see there are some differences here, in my project settings, for a start, I've got 25 frames per second so I'm going to change that to 15. I'm also going to go to my maximum time which changes as soon as I change the frame rate.
So, Cinema 4D is slightly different from After Effects. When you change the frame rate, it affects the duration or rather it reduces the number of frames to maintain the timing if you like. So, I'm going to change that to 316. We'll also go to our Render Settings and in your Render Settings you also need to make sure you have the frame rate correct. So we'll put that at 15 and just see that it's got the maximum time correct so we don't need to change that.
So once we've done that we just go ahead and save that file. And you'll see that it updates when we jump back to After Effects. So we'll wait for that to save and then we'll jump back to After Effects. And now you'll see that I have enough footage to film my composition so I can just trim it all the way to the end. And I'm good to go.
