Hi guys hope is doing well in this course.
This is live is you from a school or a line that come.
I'm very excited to have you in the section.
I'm very excited to explain to you about masques track Matt and the play composition that you will use
to pop up text on your screen in so many ways.
First I'm going to go through this lecture where I will explain about masks and their usage.
And later on we will develop slowly slowly to be able to do some great and awesome animations that you
will use everywhere.
Masks are shapes but they are different kind of shapes.
Let's have some examples.
Let's use the rounded rectangle tool.
I am OK with the feel and so on and create a shape.
Now I would create a shape that has a rectangle as it's a shape.
That's it.
Now if I choose the shape layer and I choose also the shape tool you notice the option here is highlighted.
I can either create a shape or create in mask by default it is created if I use it then I will have
just another rectangle here and we see these in complex shapes.
But if I choose create mask I will be able to create a Maskell issues for example the star tool I can
click Bashir for example or the manipulation I showed you of 48 shapes will work.
If it is now my ship did not disappear it is my shape you can see it on the blue border but a mask has
been created that's masking everything except the inner of the mask.
That's what this mask is like this.
It shows on it's inside because it's on.
If I put it on substract it will show the inverse Also if I have it on and I use inverted it will show
all the shape there.
And inside there is just a hole.
If you look at it that is the one that's pretty interesting.
Let's go through now editing this mask and this is very important rule of thumb if you choose your mask
and mask one you'll find that the corners or the nodes are squares when they are squares.
It means you can click on any one of them and move your mask.
This is pretty important because later on you will start wondering how do I manipulate the shape of
the mask to edit the mask.
Now you Yukari click just on the layer you can see it.
Now they're turned into small circles and that is a big circle.
If I click on any node I can change the shape of the mask.
Actually I can give it any shape.
Let's summarize this important point.
So when you have circles you are changing the rules you can move them around.
Also you can hold the side and move it out or in any way you want.
So it to do that and then you have a shooting star.
But when you are having just rectangles then you will be able to move the mass cannot.
So that's very important and you want to keep in mind the circles and the squares how to edit mask.
Let's look at inside our mask if it will down mass Quon you will find you have a mask bath mask feathering
opacity and expansion.
I will give you an exact size and a very good example about how to use expansion in the next lecture
for umask path.
The path is this cloud line or I don't know what color is it.
Now here we can change the color and make it very bright green for example.
Or yellow or now it's yellow.
So the mask path is this a yellow line can copy and paste this one.
And also you can see it's less animate.
This mask I would keyframe diplomatic path as we explained the my spot is the yellow one and move for
example to one second.
And I would start for example moving the mosque it's moved to here and move these not so I need to move
the knots.
I would press underlayer and move these nodes here then go back and move the mosque here.
And also move more than want to show you a good example.
OK.
So this path what will happen you have the first vertex here and here.
So you have the first vertex take that first vertex and put it on the other first vertex the first vertex
is this big square.
You can change it by the way.
But for now it's just the simple explanation I can give you.
It's an advanced level will do later on if you click on play.
You will notice that the whole mask's has moved so it's not just one note or two.
The whole thing will be moving here.
This is how you animate the mask you give it one state and another state you can give it a third stage
for example coming over here you can say OK this is my third state
something like this.
OK.
Have three animations that you really want to get the OK this North has jumped.
No problem.
So this is how you animate your mask.
It's very important that you have a good understanding of that.
Let's go to.
You can see feathering here.
If you go further you will have some kind of blow from the inside and the outside.
That's the feathering how it operates sometimes is extremely good.
We use the opacity you know what is this and expensive let's take an example about the expansion.
I will delete this mask and simply I did it just in order.
I will delete the masks altogether.
OK.
And I will take a circle a mask like for example in the middle and here now I can come to the mask.
Keyframe the expansion here.
Go to one second for example and make the expansion negative only something like this that is what's
happening.
You have a circuit that's growing.
That's very cool.
If you take the feathering up now you have even in nicer shape going down you can invert the keyframes
and you have a nice glowing wall that is way beautiful.
You notice the flaring in you can also move your mask like we said
we come to mask mask one and we can move it here to center it make it a bit smaller to size the mask
or use a free transform.
You can doubleclick on the mask any of the flitters form that you can scale down for example move.
And also you can rotate if you like.
This is a circle that doesn't make sense but nevertheless it can work.
Here you are now you have created a very nice pop up if you come back here and say this is zero or negative
whatever.
Here you are.
You see it is a nice animation.
Cool.
Now you have pop ups.
Beautiful.
Let's make the timing in between a press ultimatum move them and not just now you have no lights.
Thanks for being with me in this lecture and the next lecture we're going to apply masks to text.
