Guys hopefully are doing very well in this course and if you have any questions please put them in the
Q&A section of the dashboard of discourse.
Please do not hesitate to ask any question you have.
It is important that you understand everything in this course and you become mass and motion graphics
designer or artist even in this lecture.
Want to tackle motion path motion path is the most important concept in animating in aftereffects.
You don't understand this one very well.
Then your animation will always be basic.
Let's look at the simple animation I have created.
Is just a circle and the anchor point is in the middle and it's moving along a path that is a motion
path.
Notice that it is only the anchor point that moves on the path not the whole layer.
The whole that is connected to the anchor point and angle point moves on the motion path.
Here you can see that if you change the position of the anchor point then the whole movement or the
whole appearance of the shape will also change.
The first thing I wanted to do is to come to edit.
If you are on the Apple come to file and go to Preferences go to Genner preferences in this dialog box
you have very many options but the only options that we are interested in now is the default spatial
interpellation to Linnea.
It means set default option in position to Niinimaa.
Here you have three important words.
I would say special that is in space is not in time interpolation is how the movement is going to occur
and linear.
It means like a line straight.
So set this default ticket here and say OK and this is how I've been working all along since the beginning
of the Course because I do not want to have any curved motion path.
We'll see about that.
So this is your motion path you have created through using keyframes here in between two keyframes there
is one second in time you notice it just jumps from 0 to 1 and jumps again to 1.
So this is on purpose.
Why we are working on 25 frames per second.
So in between the two frames there is one second.
So that is 25 frames.
The big square here is a frame and the small dots are frames.
If you zoom in in your timeline you find out that you have three.
One two three and so on.
If you move in between frames on the time line also spatially in the space it will move from one frame
to another.
So when you run the animation this object or its anchor point is moving from one frame to another until
it gets to the second keyframe and that is what interpellation.
Let's explore this motion path.
First of all I can click on any iframe and move it.
So not just now I am moving the motion path and changing the motion path.
I am changing it specially in the time line here.
That is the temporal.
This is about time.
Nothing is changing spatial is about the shape or how the motion path is drawn.
I can't change it any way I want.
If I hold the key for it.
If now I come to the time line I will be changing in time which we call temper.
Let's see I make this two keyframes very near each other and of course I widen the distance or the time
in between these two keyframes.
So is what happens on the motion path.
Because the time here is bigger and the distance is still the same.
Then you have more friends in between the keyframes and because here the time in between is shorter
then you have less of.
When you have more frames.
The speed is slow.
It has to jump for every single frame until it gets to the second one.
And of course this is seen through the time line here.
When you have a few frames then the jumping is quite fast.
Let's run around previewer and see it it's slow here speedy slow speed.
That's not the rule.
It's not always like this we can't change that.
We can make almost the same time here and here we see that using.
Robyn Williams So if I change the time here the shape of the motion path does not change.
In other words if I do a temporal change then the special aspect of the motion path will not change.
So when you look at the motion path and look how it's drawn this is the special aspect.
If you look at the timing in between keyframes and how long it's going to take to cross the whole motion
path you are in a temper and that is a very big distinction.
And these two will make you understand how motion path work.
Let's take a keyframe any keyframe and just right click on it and go to keyframe interpellation.
You'll notice here we have a two interpellation the temporal interoperation and the special politian.
And we have the roving roving is a mixture of both of them.
The temporal and the spatial.
If we come here Temperton interpellation is here in the timeline spatial interpellation is here in the
shape of the motion path in the next lecture.
I will take the spatial interpellation and explain to you all the different options you have.
And it's really very amazing.
See you then.
