00:00:01,060 --> 00:00:06,130

Guys hopefully are doing very well in this course and if you have any questions please put them in the



2

00:00:06,130 --> 00:00:09,820

Q&A section of the dashboard of discourse.



3

00:00:09,910 --> 00:00:12,740

Please do not hesitate to ask any question you have.



4

00:00:12,870 --> 00:00:19,000

It is important that you understand everything in this course and you become mass and motion graphics



5

00:00:19,000 --> 00:00:22,240

designer or artist even in this lecture.



6

00:00:22,240 --> 00:00:29,860

Want to tackle motion path motion path is the most important concept in animating in aftereffects.



7

00:00:29,890 --> 00:00:32,200

You don't understand this one very well.



8

00:00:32,200 --> 00:00:35,860

Then your animation will always be basic.



9

00:00:36,040 --> 00:00:38,920

Let's look at the simple animation I have created.



10

00:00:39,020 --> 00:00:45,970

Is just a circle and the anchor point is in the middle and it's moving along a path that is a motion



11

00:00:45,970 --> 00:00:47,060

path.



12

00:00:47,060 --> 00:00:53,290

Notice that it is only the anchor point that moves on the path not the whole layer.



13

00:00:53,380 --> 00:00:59,890

The whole that is connected to the anchor point and angle point moves on the motion path.



14

00:00:59,890 --> 00:01:06,190

Here you can see that if you change the position of the anchor point then the whole movement or the



15

00:01:06,190 --> 00:01:09,000

whole appearance of the shape will also change.



16

00:01:09,070 --> 00:01:12,070

The first thing I wanted to do is to come to edit.



17

00:01:12,100 --> 00:01:19,240

If you are on the Apple come to file and go to Preferences go to Genner preferences in this dialog box



18

00:01:19,250 --> 00:01:25,290

you have very many options but the only options that we are interested in now is the default spatial



19

00:01:25,300 --> 00:01:27,620

interpellation to Linnea.



20

00:01:27,760 --> 00:01:32,060

It means set default option in position to Niinimaa.



21

00:01:32,080 --> 00:01:34,120

Here you have three important words.



22

00:01:34,150 --> 00:01:40,960

I would say special that is in space is not in time interpolation is how the movement is going to occur



23

00:01:41,380 --> 00:01:42,410

and linear.



24

00:01:42,430 --> 00:01:44,960

It means like a line straight.



25

00:01:45,100 --> 00:01:51,700

So set this default ticket here and say OK and this is how I've been working all along since the beginning



26

00:01:51,760 --> 00:01:56,520

of the Course because I do not want to have any curved motion path.



27

00:01:56,560 --> 00:01:57,970

We'll see about that.



28

00:01:58,030 --> 00:02:04,510

So this is your motion path you have created through using keyframes here in between two keyframes there



29

00:02:04,510 --> 00:02:11,790

is one second in time you notice it just jumps from 0 to 1 and jumps again to 1.



30

00:02:12,010 --> 00:02:13,520

So this is on purpose.



31

00:02:13,660 --> 00:02:17,710

Why we are working on 25 frames per second.



32

00:02:17,770 --> 00:02:21,750

So in between the two frames there is one second.



33

00:02:21,910 --> 00:02:25,320

So that is 25 frames.



34

00:02:25,690 --> 00:02:31,150

The big square here is a frame and the small dots are frames.



35

00:02:31,390 --> 00:02:35,580

If you zoom in in your timeline you find out that you have three.



36

00:02:35,590 --> 00:02:37,890

One two three and so on.



37

00:02:37,930 --> 00:02:45,820

If you move in between frames on the time line also spatially in the space it will move from one frame



38

00:02:46,090 --> 00:02:47,190

to another.



39

00:02:47,230 --> 00:02:53,830

So when you run the animation this object or its anchor point is moving from one frame to another until



40

00:02:53,830 --> 00:02:58,370

it gets to the second keyframe and that is what interpellation.



41

00:02:58,390 --> 00:03:00,660

Let's explore this motion path.



42

00:03:00,730 --> 00:03:04,010

First of all I can click on any iframe and move it.



43

00:03:04,120 --> 00:03:09,250

So not just now I am moving the motion path and changing the motion path.



44

00:03:09,250 --> 00:03:13,100

I am changing it specially in the time line here.



45

00:03:13,180 --> 00:03:14,770

That is the temporal.



46

00:03:14,770 --> 00:03:16,030

This is about time.



47

00:03:16,030 --> 00:03:23,080

Nothing is changing spatial is about the shape or how the motion path is drawn.



48

00:03:23,080 --> 00:03:26,080

I can't change it any way I want.



49

00:03:26,080 --> 00:03:27,660

If I hold the key for it.



50

00:03:27,940 --> 00:03:34,260

If now I come to the time line I will be changing in time which we call temper.



51

00:03:34,360 --> 00:03:40,870

Let's see I make this two keyframes very near each other and of course I widen the distance or the time



52

00:03:40,960 --> 00:03:42,880

in between these two keyframes.



53

00:03:42,950 --> 00:03:46,210

So is what happens on the motion path.



54

00:03:46,210 --> 00:03:50,400

Because the time here is bigger and the distance is still the same.



55

00:03:50,410 --> 00:03:57,160

Then you have more friends in between the keyframes and because here the time in between is shorter



56

00:03:57,520 --> 00:03:59,680

then you have less of.



57

00:04:00,040 --> 00:04:01,820

When you have more frames.



58

00:04:01,840 --> 00:04:03,390

The speed is slow.



59

00:04:03,490 --> 00:04:07,420

It has to jump for every single frame until it gets to the second one.



60

00:04:07,460 --> 00:04:10,860

And of course this is seen through the time line here.



61

00:04:11,080 --> 00:04:15,910

When you have a few frames then the jumping is quite fast.



62

00:04:15,910 --> 00:04:22,480

Let's run around previewer and see it it's slow here speedy slow speed.



63

00:04:22,660 --> 00:04:24,070

That's not the rule.



64

00:04:24,070 --> 00:04:26,620

It's not always like this we can't change that.



65

00:04:26,680 --> 00:04:29,950

We can make almost the same time here and here we see that using.



66

00:04:29,950 --> 00:04:37,420

Robyn Williams So if I change the time here the shape of the motion path does not change.



67

00:04:37,450 --> 00:04:45,360

In other words if I do a temporal change then the special aspect of the motion path will not change.



68

00:04:45,370 --> 00:04:50,740

So when you look at the motion path and look how it's drawn this is the special aspect.



69

00:04:50,740 --> 00:04:55,690

If you look at the timing in between keyframes and how long it's going to take to cross the whole motion



70

00:04:55,690 --> 00:05:00,680

path you are in a temper and that is a very big distinction.



71

00:05:00,820 --> 00:05:04,200

And these two will make you understand how motion path work.



72

00:05:04,360 --> 00:05:11,420

Let's take a keyframe any keyframe and just right click on it and go to keyframe interpellation.



73

00:05:11,710 --> 00:05:18,080

You'll notice here we have a two interpellation the temporal interoperation and the special politian.



74

00:05:18,250 --> 00:05:22,340

And we have the roving roving is a mixture of both of them.



75

00:05:22,360 --> 00:05:24,450

The temporal and the spatial.



76

00:05:24,790 --> 00:05:32,470

If we come here Temperton interpellation is here in the timeline spatial interpellation is here in the



77

00:05:32,470 --> 00:05:37,030

shape of the motion path in the next lecture.



78

00:05:37,120 --> 00:05:42,270

I will take the spatial interpellation and explain to you all the different options you have.



79

00:05:42,280 --> 00:05:44,570

And it's really very amazing.



80

00:05:44,590 --> 00:05:45,090

See you then.
