In this lecture we are going to explore the value of class.
I will create a new composition recall value for example a graph and here we have always used the speed
graph.
Now we can go ahead and start using the value graph and I will show you how it works and its limitations.
And what's tricky about it and what's beautiful are creating a rectangle for example here is the rectangle
a small rectangle.
I will take the anchor point of the layer and put it on the bottom of the rectangle position the rectangle
back in 95.
I want to create a dimension with scale.
I will open the scale come in the beginning of the time line make it zero percent it disappeared completely.
In fact this composition is too long.
I will come for example to four seconds that's enough press and to bring the work area and to my timeline
indicator which is right click and trim camp to work area and you will be only 5 seconds.
I will go to one second and make it 100 percent.
I can select both the keyframes and press F 9 to make them easy ease and then I can go to the graph.
Also I could have come to the graph here.
I selected them and you make them busy.
Make this one a bit bigger so we can see here.
Zoom in just a bit.
Now you notice the scale has two parameters and I can see only one graph.
If I remove the chain link if I change now one value you will notice that I have the red one moving
up and down.
So this is the graph for the first value of the x value and if I change the value of the second one
you will notice that it is the one that's moving up and down now and changing values.
So now I have two graphs.
One for the first value as a rule of thumb.
The red one is always the first value and the green one is the second value.
So we want to return them the way they were.
What I will do is just press Altan it and the link.
The first value is be the x value.
I'll come back here.
Also I place alternate link and the two values are identical.
I put them back to zero and back to one graph.
So the link here that the alternate and click on the link it will take the first value and copy it in
the second and this is the way to return them to their initial values file.
So now let's take the second keyframe and you have the handles that we can move around.
Not is what's happening to the rectangle when I move we are moving the value of the scaling.
Not as here.
This killing is changing.
Want to have more pop for example.
We can always play with the hander's.
Now I'm not what's happening here.
The graph is coming up but is going beyond 100 percent 119 or 1.20 and then coming back to 100.
So now your animation is a nice pop goal of course is very slow.
You can also have two pops.
Take this one up.
If I remember well and take this one down here you are.
You are almost there.
So now you have two pops.
Look at the value it will grow and go under.
And then comes back.
Notice if you play it cool that's fine.
These are the two pups technique now to do that with keyframes.
It would have taken a lot of work.
So this is how you can use the polygraph.
Let's go and work with some other Shipler stop the animation here.
Let's take the rotation.
This will be the rotation I will take a circle and put on the sided control shift and open it.
Now notice that the initial point I will leave it in the middle here.
I will come to rotation go to the beginning and keyframe the rotation for example at 0 to 1 just for
the sake of the example and give it a full rotation.
So now it's going to rotate 360 degrees or full rotation.
I would select both of them and rest f 9.
Make them easy is go to the graph.
Now the graph here of course rotation has a single value that not two graphs.
So you can move and see how you can create a Poppea So by changing the handles you're changing the value
of the rotation.
Of course we are in the value graph and then here we are saying that is how it's behaving.
So it's rotating in full rotation and then going beyond that is now 19 or 20 degrees beyond the fourth
edition.
And coming back to the full rotation here you are.
This is a very interesting animation that you can always do.
If you have the blower on it will be very nice.
You are fine and you can also start playing with it more.
I don't know if you can do a double pop here.
OK maybe see how it works.
Or take it down a bit here.
This way it's a long way but it will work because that is not the Bullpup is just a comment if you want
is pretty good.
If you continue playing with it adding a couple of keyframes you can do this movement up and down.
So actually this is how the movement is done.
Here you are with now two tricks and very importantly how to use Balaga to give some life to your mission.
Of course I exaggerate a lot here.
Let's stop the animation and do something else.
So now let's see what you can do with value graph and position.
I will take a circle that will do it here.
And take the anchor point of the layer and put it in the middle of the circle.
Fact I would remove from a graph here and all open position keyframe the position the beginning and
go to one second.
Use my selection tool press V and I go to the end.
So now we have just a movement here.
Let's go to the graph and stop that and we go to the valley graph.
Not this I have the two values it's linear.
So let's make it easy is we give them f 9 they will become busy and that is he is doing very well.
Of course we have two values and like we said the rule of thumb the Redwall is the first value that
is this while you see it's moving and the second one is the y value.
That's the green one.
If you move it it will move.
That's very interesting.
But now I don't have endurance.
There are not hundreds.
Well it makes a lot of sense because the hander's for a value graph for position are the handles of
the motion path.
It makes a lot of sense here because this is special and the position is always special.
The position cannot work.
In time you know if moving then you have the handles here.
They cannot control the time so you can use speed graph and it would be quite efficient.
Now if you use the speed graph let's look at the value graph.
And there is little change here.
If not but if you play with the handles on the graph you'll notice that there are changes here in the
graph and you can't really manipulate them the way you want.
So for position you do not have basic keyframes here to be able to move it up and down.
You will control that through the motion path and you will do that inspection by very nice.
Let's go and do something else.
For example now.
Stick a layer a solid layer.
I'm going to make this solid layer as big as the composition.
Good I'm going to open scale keyframe it here.
Go after one second for example and with the game.
Go to the beginning make it zero choose all the keyframes press 9 and they would become easy.
Come to the value graph we are in the value graph.
All that of course now we are doing scale but I'm going to keep it as one graph and start manipulating
and see what happens.
Now you notice here I chose this one because it would give you really what's happening.
Now you're not.
There are a lot of things that you can do here.
Now all went beyond the 100 percent so you went outside the composition.
But if you change it for example you look at this one.
Now we want return values for example now this year what's happening is going to grow
and it's quite interesting you know it's only from the beginning cool.
And you can change the values by playing the graph hander's OK and you can have lots of interesting
movement here lots of interesting animations this is very useful when you're doing transitions of course
and Kallas a bit now.
And because I want to go speedy ready at six seven minutes.
Let's see if that's what you can do.
So now we have explored the value graphs and we know it's limitation and we know exactly how it's going
to operate.
But using the value graph and using the special interpellation and the other graphs you can really come
up with something very beautiful lurcher go to after effects and start playing with this.
Does that complicate your lives.
Don't break it into two graphs make the graph and try to play with.
Thanks for listening and the next lecture will see how to do some exercises.
