From our work flow we are going to start with that point.
Step one is applying the effect.
And of course creating the track points seeing exactly how it works and the different options that you
might have if you want to follow along with me.
Please open the project file.
Commit at tracking dot AP within this project please open Kamelot tracking Althouse as DoubleClick on
it.
We only have the video of the old house.
That's first of all look at the video you'll notice that the House is not moving and that we have a
camera that is zooming in somehow and it has a certain motion.
OK it's not going straight just moving at a certain angle.
So now let's use 3-D come out tracking to track the camera movement that has been used to shoot this
video.
You have two options here.
You can come to the tracker and click on track camera or you can come to ethics and preset and go to
perspective.
And you know as you have 3-D camera tracked.
Let's use the camera from the tracker here.
Click on it you immediately start analyzing in the background.
Step one of two and the effect 3-D camera tracker has been applied to the video.
You have several options here.
You can cancel and you have the shot type down here.
You'll notice you have two main options fixed angle of view.
That's the one that's working on and valuables should have been interesting if used the valuable zoom
here in our video because we had a lot of zoom here.
It could give you better result but we see that later you have other options also.
And the advance we will work on it now is starting to solving the camera solving the camera.
It means it's trying to find out what kind of camera it's going to create for you and how it's going
to create the motion of the camera actually.
It will not create the camera it will just study how a camera can be created.
As soon as it finishes you're not is that good come into option has a built if you click on it it will
create a camera.
I will do that.
If you are.
You got this.
There is the 3-D camera tracker.
That's a camera that has been created.
And if you press you position and orientation is being framed.
So emotion has been created.
Let's see this motion.
If you come to view these until of course you know that from the 3D section you know the camera is over
here and the position and orientation has being keyframe and the camera now is moving and it replicates
exactly the movement of the camera used to shoot the video.
Not is that the old house is not in 3-D doesn't make sense to put it in 3-D but any other layer that
you want to use through the camera tracking will be in 3-D.
OK.
Let's go back to a single view and select the 3D camera truck.
Notice how there are these Xs all over there.
These are the track points.
OK.
And you are going to use these points to define certain areas or certain plane to odd objects in 3D
or not is that there are very few on this side over here.
Aftereffects has done its best to look at certain track points so you can use them in the 3-D tracking.
Now there's a bit about this duckpond through you or not is that some track points will appear all along
the video and some of them will appear and disappear and some of them will just disappear after having
appeared.
So actually they're not all stable at 100 percent.
This is the effect of the tracking in some frames after the fact did not manage for example to find
the track point over here.
So I decided OK let me deleted or remove it.
OK.
You cannot this from this guy over here.
It wasn't that.
Then you start finding it.
And he goes on I think the.
And now it does appear they get.
So these are the track points and you are going to use them to define search and plane to put your 3-D
as later on that is that we have very few track points over here.
Aftereffects is not taking care of this.
We can go back to the fix and get view and change it to vibrate but resume.
Now it has the results again for the valuable zoom.
I notice you have the camera again.
Let's create this camera.
But usually you won't do that you will have only one camera.
But in our case here we have one camera that doesn't use the zoo and another camera that uses the zoom.
This is more precise if you like put the biggest camera OK.
And then let's select the old house or the effect itself.
And you know this was the new camera.
You have much more track points around here.
It means after effects has taken care more of the zoom and created more track points.
If you want by now you have applied the effect and created the track points.
You know there's this circle moving around.
OK jumping out of this circle.
We'll use the track points to define a 3D plane on which you can attach different kind of 3-D layers.
And this is what we are going to do in the next lecture.
Thank you.
I will see you then.
