Guys in this lecture we can't use masks and you will learn how to animate mosques how the interpretation
of the ammunition that you create is done.
And the concept of the first Virtex within the animation before we start animating our cats over here
is create a new composition and call it mascot Trius.
Five seconds is OK.
And we click OK I will create here a shape player.
I will create a rectangle shape to fill the whole composition.
Well I have to do is just to double click and I learned something very new here.
It's quite good.
Now I want to create a mask on this shape player.
What if you select for example the polygon instead of to create a shape you will use to create mask
you highlighted.
OK.
So now everything as has also come over here.
And click to create our polygon.
Here it is.
So let's pull up the contents we don't care what you animate them ask if it were done here.
You always animate the path.
This will elevate the mask.
You can animate the feathering opacity and expansion if you like.
If you click or mask path you have created a keyframe that is set for this shape of the mask or this
state if you like I'm going to change the mask points because they're of the same color.
As usual the yellow in this case it will work.
Yes.
So Yuuki for this mosque in this kind of shape and each point has its own position.
Now let's come after one second OK.
Was there the selection tool.
Yes we you can click and drag the mask over here pretty easy.
Now you created an animation where the masks move from one position to another position actually from
one state to another state.
And then after effects is doing the interoperation in between could come over here click inside.
Let's try to change the points position.
I'll click on the left one and take it to the right.
OK.
Click on the right one and take it to the left.
As simple as this.
Try to make an eye shape fight.
So now if you jump to the first keyframe and you scrape through what is the interpellation that after
effects has done in between the two states.
If you scrub through not just what's happening is trying to preserve the animation for each point meaning
let's select this point you can see it and if you come back over here it is the same one selected.
So it's trying to move this point from this position from this date to the second state as simple as
this.
OK guys.
And it does a very nice interpellation pretty logical by the way.
If you decide OK I want to change here that's no problem.
You can change them for example like this.
And again you have a different interpellation and a different change in the mosque.
Now I will do this too.
There is the concept of the first Virtex.
This is the main Virtex if you like.
So over here we have the first Virtex on this point.
And in the beginning we have the first Virtex on this point and this Jesus has come to the second state
and exchange the first Virtex to this point.
All you have to do is to right click go to mosque and ship path and here you have said this one to be
the first Virtex here you are.
So this is a state now because you change the Virtex script through aftereffects will always match the
first verses.
Here you are if you scrub.
Look what's happening is going down and trying to match it.
But in all the whole kind of animation or the whole interpellation has changed totally.
It's pretty cool by the way to this point.
Or let's take this point here Right-Click mosque and ship path and said this one to the first Virtex
is going to match it with the other one.
Here you are you can see it now very nicely.
So actually this is the concept of animating masks just to create a state if you like how the points
are positioned within the mosque.
And then you jump in and you create another one including moving and rotating.
Let's see another option here with the ship.
So we have here a polygon.
Let's go to the next keyframe and click and say OK we want to reset it to a rectangle.
I click OK.
And that is here we have one two three four points.
OK.
If we come back here we have five points here.
So after effect is going to interpret it as find a certain position for the missing point from over
here.
It's actually Zappy at one frame before you can see it.
Here then comes here.
It has disappeared.
This is pretty cool.
And you must appreciate this intelligence is really very nice.
If you come to the federal You can also animate the fact that I will keyframe over here.
But the feather at 0 coming over to the next state or in between if you like and you increase the weather
let's make a big value and then you have the feathering being animated like any other property.
No big deal about it could do this.
And then the opacity you know very well you can animate it from 0 percent to 100 percent.
So you can only make the mask expansion.
Let's create a keyframe here.
And the value is 0 0 for example come to the other side and let's reduce the value just for the example.
And it's pretty neat.
The expansion will have a lot of use later on when you're doing mask tracking for example.
So this was about how to animate masks and the concept of the interpellation that aftereffects does
and the concept of the first vertex.
Thank you very much for listening.
I hope this was extremely beneficial for you and please review this lecture a couple of times.
So you are very comfortable with mask the mission and the way it happens.
I would see you in the next lecture.
