Guys in this lecture we wanted to explore that trace path and you will notice how amazing is going to
become to use this kind of motion graphics and extremely useful when you're doing bath or masks on videos.
But let's take a very simple example what is the trace path.
Let's go to our player and select our path and create a trace path.
Let's click on it.
There's a new layer has been created.
This is now 50 for me here.
If I press Enter I'm going to call a trace path or trace the way you like.
And let's go now and see what happens inside the trace path.
Non-ladder you will notice now there is an effect and in this effect you have trespassed effect.
Double click on it and it will open in the effect control.
You will not that is progress and Lupica.
Well that's pretty interesting.
And you have to keyframes over here.
Let's drill down.
We have these two keyframes.
If you scroll through you will notice that the null layer is moving along the path itself or the line
or our graph if you like.
But also there is something else that is amazing.
You'll notice that it is oriented according to the path.
Here you are not going to change orientation.
Here it is.
So let's attach some graphic to it and see exactly how it happens.
Let's go to our project here and we have the car.
Then I will take the car and drop it inside the composition.
It's a very big car that's cool.
Now presented to the trace path.
Our click on the week but our press shifted to make a jump to the position of the lab itself.
So it jumps over here.
It is upside down.
You'll see why it's upside down later on.
But then we can open the car.
Now the scale I make it for example 30 percent on the cut is still upside down.
But if you step through as soon as you start here you are.
It is in the direction of the orientation of our path.
Good to rectify this if you like just a couple of frames from here is no problem.
Here you are it shows like it is completely straight.
OK.
Of that if I press space but now notice how the car is going very fast along the path and not is the
orientation is already fixed.
Imagine how much work it has saved you or you already have the whole motion and you could lose.
If you're doing some animation or some presentation you are really done.
And it's pretty nice.
Guys let's look at the spot itself and we said we have an effect here and we have two key frames I want
you press space bar to plate.
Now if you take the time or the last frame if you like and make the time longer notice how it goes now
much.
You are.
You can even make it mass you know slow you are.
OK so these two key frames are determining how the progress is.
If you take it now very near you have some crazy animation going guys let's take it to two seconds.
We are here.
That's pretty cool.
The loop here is going to loop these two keyframes.
If you pull the loop off if you are it sticks to the end of that it does.
Right.
OK.
Or simply you can take this keyframe put it in the end if you like too.
And if you play it's very slow now for us.
But the car will come at the end of the path when the time is over all the animation is over here you
are pretty cool right guys.
So imagine how much saving you have.
First of all you forget about the orientation oriented path.
If you remember and you forget about the loop out expression it's already all done for you.
Of course this is a naive animation but it's pretty cool guys don't you think so.
So this is about the trespass as simple as this.
The applications here are very many and trespass can be very useful.
OK guys thank you very much for listening.
I'll see you in the next lecture.
