Hi guys.
And welcome to see two thousand eighteen Abed's in aftereffects.
There is one of them that is really tremendously helpful and I encourage you to learn it and start using
it.
It will change the way we used to use mask and path actually is extremely powerful for certain animations.
My aim in this section is to explain to you how it works.
The concept and I will add a few simple examples later on we can expand on these examples and use it
with your videos with a lot of motion graphics and can do power for motion graphics.
Believe me.
So let's create a new composition in 2018 and click on new camp in the middle and let's keep it compline
we don't care 12:18 by 720 is OK for the course but you can come and choose whatever you like.
Let's create our comp within the comp I will choose a rectangle.
But I would create a busy path a rectangle.
Here you are.
So make sure the path is select.
I would draw just a simple thing.
Now within the rectangle you know very well that is path 1 and there is path.
This is because it's a busy.
I'm sure that at this stage of this course you already know how to animate the path itself.
You click on the stopwatch to start the animation come after some time whatever it use your selection
to shift to click on the path and then you can start moving the points.
I'm going to call them points from now on because this is what I do.
After Effects started calling them and not vertex or vertices.
So you can change the point as you said for example something like this.
And then you have an animation with the mask.
Pretty cool pretty fine.
Very tedious to me.
On a 10 or 20 seconds.
I would read the keyframes here.
Go back to the original.
Now I will select the busy path to use the new feature or do you go to window and at the bottom here
you will find create nulls from path that GSX.
So it's not an effect.
If you click on it and the panel create nulls from path it will appear.
Actually it will be a floating panel.
I just put it on the site.
It has three options here.
Point follow Nona's.
So these are the points and surely some nulls are going to be created nulls.
Follow the points or trace path.
Let's focus in this lecture on points.
Follow nuts now.
First of all you need to select your path.
If you select only or later and you go points for nulls it will give you an error.
So you need to select a path.
Here you are.
I will go point for on nulls and then for nulls have been created connected to the corners.
Let's change the color here.
Let's give it for example something yellow we can see them yes.
I will unselect.
Now you have 4 nulls here that are connected to every point of the path.
So now if you click on one NULL for example and start moving it you'll notice that the point is moving
with the null.
This is pretty awesome.
I'm sure you already have a lot of ideas how you're going to use it and for what you are.
I will all this let's create a very simple animation of course to the point you will be animating the
nulls themselves.
Select all of them before position.
Here you are then come after some time here and just select one of them move it.
You notice you have a motion path which is pretty cool.
OK I'll move it and not.
I have a motion pass here and another one here.
Very very efficient.
And now I don't care about you know how the path is and keyframe it all along the way.
In fact you got one single simple animation with very little work.
So animated now a busy shape or a path has become very easy.
This is the concept of appointer follow nod's meaning it will create the nuts for you and you can make
the nuts.
That's very fun.
Then select all of them here and just lead everything.
Now let's go to the pen tool and that's going to be interesting if you draw a path.
Here you are with the pen tool.
Let's bring this one here.
And this one like this.
Now I will select the shape that this is of course a busy shape that inside shape once you have a path
one and have other path I say points follow the path.
Here you are.
I don't know why is creating with this colored JELAS from my shape and I would change the color here
too.
I don't know Lavander this time.
That's better.
So now you have the full knowledge and you are able using position for example you will be able to animate
each and every one of them in the next lecture.
I will give you a very nice example to do line graphs.
I'll see you then.
