Setting up a scene for export and setting the origin and ground plane

…Now that we've solved our camera, we want to go…onto the next step in the workflow, and create a scene.…So we'll press the Create Scene button.…And the camera tracker will create a camera, and a camera's linked…to a null object, which you can think of as the main controller.…Which we'll come to later on.…So, if you want to, just twirl up these…setting here, because we're not going to need them anymore.…And we just want to focus on the 2D, 3D button.…I'm going to press this, and, this moves into our point cloud view.…

So, in the active camera, you can't really make much sense of it.…So you want to switch to one of the custom views.…So now, if we look in scrub through, we can see that the…motion of our camera has been, translated into this After Effects camera here.…But we want to, tell Camera Tracker, if we just zoom in.…It's got no way of knowing which way is up, which way…is down, all those kind of things that are useful for later on.…And you can see that the ground is kind of sloping downhill here.…

So we want to fix that, by setting a ground plane.…
