Guys and will come to Musk's this is a very important section is the section that will lead you to work
with videos and even motion graphics the way you would like and you need to practice practice your hand
practice visual and try always to perfect your methods and create your own the project file for this
section is working with masks.
You don't need to open it now.
You can open it at the end of the section and see exactly how we have done everything.
We are going to start from scratch.
Import our videos and start working on Musk's.
So let's go right to the project panel right click and import file.
For this section we need that specific files.
I want all the files that Swan And we need the reverse.
So I press control.
I get the reverse.
And then of course we'll click Import to bring in the file.
We can use the cut 33 16 to start our work.
Click on track and to create a position from this video.
So what are masks masks will mask your layer.
It will show or hide certain parts of your hair to create masks.
Use the ship tools and the pen tool.
Let's start with the ship to here.
Let's create a simple mask using the ellipse.
First of all if you don't select your Land Of course you'll be creating a shape here.
So I will undo that to create a mask.
You need to select your layer and then click and drag to create a mask.
For example click in the middle and notice that everything has disappeared because the only thing that
are going to appear by default is what's inside the mask.
So I press shift and control and drag out to create a perfect circle.
If you remember you can use the space bar or so to take it down or to move it around to put it over.
The first thing you do after the Create the mask is to click on the time indicator and scrap through
to see if your subject that you are trying to mask all the area is always included within the mask.
In our case here we are.
Call is not the so you created a mask from the surface.
Let's look at the shape there.
Here we notice we have masks.
And of course it's masks so you can have very many.
And we created mask one you can rename must gwon you press enter and you give it another name for example.
Got had Ereli people renamed them.
Unless you have something complicated let's destroyed them masks and you not is that you have four properties
here that you can animate pretty interesting.
An art so you have the attribute of the mosque which you can have I add subtract and so on would see
that it now the first thing I went through is inverted.
You notice that the mask that you have created is showing only what's inside the mask.
So this is the control of the mask and inside that's what we are going to see.
But if you click inverted you'll see everything outside the mask.
Makes sense to you.
Vaizey mask Pathi it is the shape of the mask.
In fact it's a path and you can.
And he made that you can come over and change the shape or show this.
Now you click on shape and the top left right and bottom are the coordinates of the mask within the
composition.
If you turn for example either right here and you click OK.
You notice that you distorted the mask a bit.
So these are the coordinates of the corners of the mask.
You can choose the units here which we usually never do and you is that the mask shape you can reset
it for example to elipse if you like to it's an ellipse already.
So let's reset it to a rectangle.
So click OK.
It has turned it into a rectangle.
I'll get back to elipse.
You are fine.
Now there is the mask feathering the mask feathering just feather the mask meaning it to create a blurred
area around the mosque.
You see how it's blurred.
You can only get it positive outside the mask.
So it's pretty cool like this.
See very many videos and movies that use this feature.
You can also get further on on the presented here.
Or you can feather on the vertical only depending on what you want to do.
OK.
So I will undo this and keep it that that there is the mask opacity the mask capacity will play on the
opacity of what's inside the mask.
For example as 0 you see nothing.
Of course it's zero opacity at 100.
You see it at full capacity.
Now there is the mosque expansion here for this.
I'm going to put the mask feathering to zero.
You can expand your mask meaning make it bigger.
This is pretty useful if you use it with the feathering.
OK guys you can also shrink it if you are inside.
So this is all about mask is pretty easy.
You put a mask and you can inverted or keep it the way it is and you have the properties that later
on we can start any meat.
Thank you for listening and move on to the next lecture more about masks.
