Hi guys I'm welcome to this new election this lecture.
We're still in Takhar and we want to track position and scale.
Now scale is a bit different but pretty easy to use and you really need to learn it because it will
give you a lot of adventures and you can really work some fancy animation with it.
So let's have a look at our video clip here.
You see the guy is going all way moving away from the scene in front and his becoming smaller.
I think this is a very good example to use now the scale here will attach the scale to the guy.
And we got some tracks and some balls maybe.
And to see it's coming up.
Now this movie is very big or very long.
We want only to do 10 seconds but you will know that the tracking would track in the earlier panel over
here.
And it will track up to 24 second so we need to stop it when we finish.
Let's start with Kuntar tracker.
And we say track motion we have running and before because I opened the panel and we add the scale so
I'm tracking the position and the scale.
And of course I have to position the track on the first one I want to put on it on his head.
And the second one I'm going to put on his pants here.
You know the contract is very big here between the black and the gray of the road.
And also for the upper part the head is also a great contrast.
So it will work very fine.
So what I will do I need to take this track points and put them one on top.
Here you are put it in the middle.
Let's make this one a bit bigger.
It will work better.
And then let's take the other one and put it down.
Now I'm not very sure this is going to work 100 percent.
Even me I have to try.
So you will analyze the first one if it doesn't work you analyze it again it's no big deal.
And if it doesn't work at all then change your mind before buying another one.
But actually it will always change.
You need some patience sometimes you know stop being looking at the keyframes moving the track points
a bit concerning keyframes like we had done before.
But at the end you can almost track anything provided it is not too small to be tracked.
So I will analyze forward here and see exactly if it is working.
So I have my first point here and second point your call.
It's working until now and I want to stop it at 10 seconds.
Let's see when it becomes very small.
Well it's still tracking.
This is not tracking very well.
It's moved on the right but it's still OK.
We can still use it.
The head is very very good.
Fine.
Now we are coming to the end and everything is still fine.
Good.
I will stop right here.
Let's go and open the you for keyframes.
So if I come to the end here and select all my keyframes that are outside the work area I will just
delete them that's OK for us.
Now what I will do I will come to the opposition panel and enter some text.
I will write arraigning
is good.
OK you can write anything you want.
Of course now and I will position it nicely.
Now the most important is the anchor point here.
Be careful that good point is on the side.
What that will do is to put the anchor point in the middle by pressing control alt and home after selecting
the lead.
Of course we start now at tracking this one.
I will come to the later panel and choose my player find the tracker is here I get to say the target.
Running is good.
That's the text.
OK.
I would say OK.
And of course I have to apply remember always to apply X Y.
Cool.
Now it's coming on top here.
Let's look at what we have down there.
First of all for the tracker we have two points.
We have tracked point 1 and 3 point to we adjusted them.
But there is nothing about scale.
There is feature center feature center at that point at that point.
So aftereffects is going to use the attach point information to create a certain scale and it will vary
between 0 and 100 percent.
Let's go back here we have our scale but it appeared on top because this is where the first flashpoint
is fine.
Let's go.
How do you fix this one.
Using the anchor point of the ladder just move it to the right or just move it down.
OK that's good.
So now it's in the middle let's look at it at 100 percent.
It's not bad.
Is in the middle.
That's the select and run and see what's happening.
I would go to preview and click mode.
So that's pretty cool you not jumping too far.
But you get the concept here.
So after effect is going to use the top the track points to that use a certain animation for the scale
and certain percentage for scale.
Now let's add something else let's take a basketball it's not here I want to import a file and bring
in a basketball here in.
So that's my basketball.
I'm going to take the basketball come to the beginning take the basketball and just drop it here.
Good.
And let's make it smaller.
Here we are.
Now I want to you know also track the on the basketball.
I will come to truckle go to the panel choose my player.
That's my lay out here.
And when he says did target I will choose basketball running that Benji.
Here you are.
And apply same same.
You will notice that the basketball came on top.
I would come to the BNZ.
That's the basketball side you know.
And started using the anchor point to move the basket ball whatever I wanted.
Let's put it here and then let's put it down over here.
Just next to him.
Good.
Let's run and see if you have done a good job.
And here you are.
You have the basketball and the guy and the name aligning all together and it's pretty cool.
Not just what's happening now.
The basketball is too high.
Maybe we want to bring it a bit lower so we'll take it and take the Antal point a bit.
Let's move this up.
Take the anchor point and stick it down or further and let's see what happens.
So the ball is coming with his feet it's pretty nice.
I could put it next to his feet but that's OK.
And it's bouncing ball.
So now this is how you use the scale and it's pretty easy.
Didn't have to know what is the scale and how big is it or how small it is.
And the you know the juice percentage is just direct with aftereffects.
And this is the way to create lots of animation and lots of visual effects with aftereffects.
Now of course here the wards are jumping to much what you can do.
You can come to the position of the doctor here and open the motor.
Let's see his mother is already open for me.
This mother will just reduce the number of keyframes inside a property.
So this is a special path here I would say it is.
It means reduce by 5 percent or whatever.
Tolerate 5 percent whatever it is and click apply not just what's going to happen in the keyframes are
being reduced if I play again they will reduce if I put 10.
Also now it will reduce even more.
But they do work.
It is not like if you reduce the keyframes it's going to be smarter.
No not really.
What's going to happen is the path in between keyframes will be just a bit longer and it will be you
know not jumping so much in between keyframes.
So here you are.
This is how you scale and this how you use the tracking scale and position at the same time I see on
the next lecture.
And please have fun.
Please go to after effects and start working on the tracking make nice things adjust this one for example
and download this project and play around and see what you can do.
