00:00:00,320 --> 00:00:03,100

In this lecture we want to work with Time Warp.



2

00:00:03,120 --> 00:00:05,430

So let's doubleclick on the composition.



3

00:00:05,450 --> 00:00:08,530

Open it and we have our nice movie here.



4

00:00:08,550 --> 00:00:12,710

We are already working with this video and we have the swinging bulbs.



5

00:00:12,750 --> 00:00:15,430

So it's a quite a good demonstration with this video.



6

00:00:15,750 --> 00:00:19,740

Now aren't you stretch your imagination and show you for this video.



7

00:00:19,740 --> 00:00:25,860

Because I start imagining what you can do with other videos that you shot at home at work or even professionally



8

00:00:25,890 --> 00:00:32,340

what you can do with them and what kind of skills you can develop and expand really your imagination.



9

00:00:32,340 --> 00:00:40,950

So first of all we have the composition here that is 25 frames per second and our video also if we come



10

00:00:40,950 --> 00:00:45,820

to bulb's dancing bulbs we also have 25 frames per second.



11

00:00:46,020 --> 00:00:48,910

And this is a 12 seconds video.



12

00:00:49,170 --> 00:00:51,790

And at the end here also we have 12 seconds.



13

00:00:51,870 --> 00:00:59,910

So we notice that the frames of the video are equal to the frames of the composition itself.



14

00:00:59,910 --> 00:01:01,920

So we have here around 300 frames.



15

00:01:01,920 --> 00:01:08,820

I want to draw your attention to the fact that Moore is distorting time making your video a speedier



16

00:01:08,850 --> 00:01:15,990

or slower depending on your needs and it has some nice effect that I will go to eFax and present go



17

00:01:15,990 --> 00:01:20,920

to time and have time warp and take it and drag and drop it on the layer.



18

00:01:21,240 --> 00:01:29,730

Now timewarp is a somehow develop and complicated effects all we want to do is to work with the motion



19

00:01:29,730 --> 00:01:32,130

blur and speed here.



20

00:01:33,030 --> 00:01:35,600

Or source of frame so we will do.



21

00:01:35,600 --> 00:01:37,340

This lecture will be about speed.



22

00:01:37,470 --> 00:01:44,690

The next election will be about source frame so I will work with speed as soon as I put the effect timewarp



23

00:01:44,820 --> 00:01:48,210

the speed dropped to 50 percent.



24

00:01:48,300 --> 00:01:53,150

If we play our movie here we are not is that the movement is at 50 percent or something like this.



25

00:01:53,170 --> 00:01:57,430

OK so let's put this bit for example at one hundred.



26

00:01:57,450 --> 00:02:00,890

So that isn't a normal speed it's 100.



27

00:02:01,230 --> 00:02:05,270

That's pretty cool but what I can do is do keyframe the speed here.



28

00:02:05,400 --> 00:02:12,720

I will come to the later press you get to see my keyframe over here as go to have a second something



29

00:02:12,720 --> 00:02:20,520

like this and the keyframe Again the speed and make it let's say 500.



30

00:02:20,530 --> 00:02:21,880

Now look what happens.



31

00:02:21,880 --> 00:02:25,930

Start slow at 50 and gradually it goes to 500.



32

00:02:26,110 --> 00:02:32,560

That's very beautiful what I want to do here is to change to hold keyframes because it will stay 50.



33

00:02:32,560 --> 00:02:37,500

Then it moved to 100 or 500 southerly and you can see the difference.



34

00:02:37,660 --> 00:02:40,450

So it starts and moves very fast.



35

00:02:40,450 --> 00:02:43,780

Now I wanted to run at the end and show you what happens.



36

00:02:43,780 --> 00:02:46,090

Not is that the speed was 50 here.



37

00:02:46,090 --> 00:02:47,110

That's pretty cool.



38

00:02:47,110 --> 00:02:52,810

It used several frames or hundreds of frames or 50 frames from the video clip.



39

00:02:52,960 --> 00:03:01,610

When the speed came to 500 It also used all the frames that are available and suddenly it has normal



40

00:03:01,720 --> 00:03:02,420

frames.



41

00:03:02,530 --> 00:03:07,490

You know it's becoming just still because there are no more frames to move.



42

00:03:07,630 --> 00:03:14,140

So actually if you want to use timewarp professionally Maybe you should the movie much longer than what



43

00:03:14,140 --> 00:03:15,010

you need.



44

00:03:15,010 --> 00:03:19,360

Sometimes it works and most of the time it doesn't work because you have an action movie something like



45

00:03:19,360 --> 00:03:19,890

this.



46

00:03:20,200 --> 00:03:25,290

So we bumped up the speed to 500 what we can do is coming here.



47

00:03:25,300 --> 00:03:34,540

We can keyframe again here you are and take down the speed here to let's say 20 only and let's look



48

00:03:34,540 --> 00:03:35,880

at our movie now.



49

00:03:35,950 --> 00:03:43,630

We have a nice one speed goes up and speed goes down and we still have few frames until it will stop



50

00:03:45,370 --> 00:03:50,880

let's take six seconds that will be OK and we can trim the work area here.



51

00:03:50,960 --> 00:03:57,800

Now in this year if I move the keyframes I make this one hour run out of frames here are video frames



52

00:03:57,800 --> 00:03:58,350

here.



53

00:03:58,550 --> 00:04:00,150

Fine so I'll put this one back.



54

00:04:00,170 --> 00:04:01,460

I still have some flames.



55

00:04:01,510 --> 00:04:02,390

Two movies.



56

00:04:02,390 --> 00:04:04,670

Let's put some emotion here.



57

00:04:04,670 --> 00:04:05,800

Enable motion blur.



58

00:04:05,960 --> 00:04:07,530

And I find this very interesting.



59

00:04:07,590 --> 00:04:11,780

I would like you to look at the bulbs and also look at the background what's happening.



60

00:04:11,930 --> 00:04:13,480

Let's play our movie.



61

00:04:13,490 --> 00:04:20,500

It comes in and when the speed goes up we have a motion blur of five samples on the bulbs you will find



62

00:04:20,500 --> 00:04:25,700

that five samples for certain frames which will create the motion blur.



63

00:04:25,970 --> 00:04:28,020

That's pretty neat and pretty cool now.



64

00:04:28,230 --> 00:04:28,750

OK.



65

00:04:28,820 --> 00:04:32,130

So this is about the time warp speed.



66

00:04:32,210 --> 00:04:34,120

You can make the speed the way you want.



67

00:04:34,120 --> 00:04:36,930

Let's return them to be frames.



68

00:04:36,950 --> 00:04:41,380

We go to keyframe interpellation I make them all busy here.



69

00:04:41,420 --> 00:04:42,070

OK.



70

00:04:42,260 --> 00:04:43,020

Here you are.



71

00:04:43,130 --> 00:04:49,870

Now the speed is incrementing to get to 500 and then it stays to five and start dropping down.



72

00:04:50,000 --> 00:04:56,650

Let's see here the effect goes up we needed to Aranda completely.



73

00:04:56,660 --> 00:04:58,720

Now we can see it in real time.



74

00:04:58,790 --> 00:05:05,650

It's quite interesting how we can play with the speed of a video using its own frames.



75

00:05:05,690 --> 00:05:07,670

Be careful we are not spinning it.



76

00:05:07,840 --> 00:05:15,410

So there are frames here that are you know moving faster or the sequence of the frames is much speedier.



77

00:05:15,410 --> 00:05:17,440

So maybe here you are moving at.



78

00:05:17,750 --> 00:05:19,730

I don't know 120 frames per second.



79

00:05:19,880 --> 00:05:24,070

So this is Tamwar and it's quite easy to use it in this context.



80

00:05:24,080 --> 00:05:27,570

So now just imagine what you can do what more can you do.



81

00:05:27,590 --> 00:05:35,390

So I'm making it here pretty simple for you to understand how to use the time or unamusing just speed



82

00:05:35,480 --> 00:05:37,030

and the Enable motion blur.



83

00:05:37,220 --> 00:05:43,310

Of course the other Palamedes is that we have here are pretty complicated I would say for time games



84

00:05:43,370 --> 00:05:44,240

in this section.



85

00:05:44,240 --> 00:05:48,950

Later on we will see how to use them all as effects in aftereffects.



86

00:05:48,950 --> 00:05:50,900

Thanks very much for listening for this lecture.



87

00:05:50,900 --> 00:05:57,200

Now pick up a video that you have maybe while you were having your dinner and speed up and slow down



88

00:05:57,470 --> 00:06:03,110

how you're having your dinner and the speed of you're there already or dance with your girlfriend or



89

00:06:03,310 --> 00:06:06,190

you not driving your own car or something like this.



90

00:06:06,230 --> 00:06:11,420

So go should some movies come back to after effects and play with them or go get some movies from Pixar



91

00:06:11,470 --> 00:06:16,950

Bay or anywhere else and come and play with them here to be able to create anything you want.



92

00:06:16,970 --> 00:06:18,850

It might seem very simple to you.



93

00:06:18,860 --> 00:06:25,310

It is simple to use it I don't want to complicate it but actually the applications are so many.



94

00:06:25,370 --> 00:06:26,740

See you in the next lecture.
