Hi guys in this lecture you are going to understand at 100 percent the concept of motion path and if
you don't please ask all the questions you want to ask in the Q Any section of the course.
It's an important concept and I will be very happy to help you understand the concept of motion path
and it's very easy very simple Don't worry about it.
Just try to notice a few things.
Let's start out create a new composition and I would take 12 80 by 720 and please work with me.
Make sure that the frame rate is 30.
OK this is important because I'm going to talk about the frame rate and then of course make it 10 seconds.
It will do so now that you have your composition.
I want to remind you about a couple of settings.
First if you go to edit if you are in the macula think on the aftereffects you see you go to preferences.
And here you go too general.
Remember there is a setting that you put a default spatial interpellation to Kenya.
What what does it mean.
There are three key words here are the five actually spatial.
It means it is in space not in time.
It's in space not in time.
It is spatial not Templer interpellation it means the interpretation of the motion path or how it's
going to occur and linear.
It means straight lines and not curved lines or circle lines.
So spatial space interpretation and linear make sure this default is checked like.
Within your composition preview.
It's important that you put Tuggle mask and shape path visibility on OK so make sure it's on.
If you can't see the motion but the on that to put it on and off and in the preview please make sure
that the last I can is checked.
This will allow us to see the motion path when we have a preview.
Let's create a motion through space and time that is spatial and temporal.
Nice terms but they're going to appear in after effects.
And you're going to use them.
Let's take for example a circle.
OK click on the stool click and drag and create the circle.
So the anchor point jumped in the middle of the circle.
If you don't have it use the anchor point door to bring it in the middle.
If you want to limit through time and space you will need the position that's key from the position
just over here.
And then let's move down the time I will move now in time.
Notice I moved in time for one second.
Then let's move in space.
Here you are.
So when you moved in time and you move the space a motion path has been created as simple as this.
Let's do it again.
Let's move to two seconds.
Here you are.
So we moved in time and then we move in space and another leg of the motion path has been created.
This move again in time and less move again in space.
So this is spatial.
This is temporal.
Any new motion path has been created or a new lick.
Let's go to the final one at 4 and move again.
Here you are.
I stop the animation at 4 seconds.
If you skip through now your element or your shape is moving through time and through space that's pretty
good.
So this is how emotion path is created.
Let's look at the special aspect of the motion but first of all you have these big squares here one
and two and three.
These are the keyframes.
That is if I click on this one it will highlight in the timeline.
These are the keyframes.
You can click in space and change the position the special position of this key frame.
So you are changing how you are looking at the path or what will be the path itself.
Nothing to do with time just moving it.
I don't now these small dots here are the frames.
Remember our composition was 30 frames per second.
So here you have 30 dots.
Why.
Because we have one second between this frame and this frame.
There must be 30 frames per second.
Now if you zoom in I will use this spot here to zoom in and to show you frames per second here.
So not this you can jump one frame at a time.
Here you are.
This is Entine Templeton.
I'm going one frame at a time and you notice that also spatially it's going one frame at a time as simple
as this.
OK.
You can use Page Down to move down in the timeline and in the space one frame at a time or page up saw
this is the representation of the motion path frames and keyframes.
There's something else here.
Let's zoom out.
Go back to normal and let's take this keyframe click on it and move it.
But I'm going to move it very neat to the second keyframe nothing nothing has happened in time.
So I still have one second in between the first second keyframe and one second between the second keyframe
and the 33.
But if you notice the space in between the keyframes here is at least visible and the space here is
totally not visible which means it has to traverse all these frames in one second is going to go speedy
and all these frames in one second.
So it's going to be slow.
Let's try it.
If you don't believe me you do not.
This is the special visualization of the motion path.
And you can come and throw it the way you would like.
That will be very interesting to draw motion path very easily.
You really don't have to hire us to go to the keyframe let's look at the temporal aspect here.
I take this keyframe and that it towards the next keyframe.
That's what's going to happen in the motion path here.
So obviously in the timeline here I know that I have more time in between the first and the second than
in between the second and the third one.
And visually I can see that or especially if you like there are more frames here and are new to each
other meaning this animation is going to be somehow slow.
Be careful.
I could have 10 seconds.
OK.
But this one is surely very fast.
This play
up.
So actually this is all about the motion path you create it through movement in space and movement in
time using for example the position in the next lecture about interpellation.
