1
00:00:01,500 --> 00:00:08,540
Guys in this lecture we can't use masks and you will learn how to animate mosques how the interpretation

2
00:00:08,580 --> 00:00:10,590
of the ammunition that you create is done.

3
00:00:10,800 --> 00:00:17,010
And the concept of the first Virtex within the animation before we start animating our cats over here

4
00:00:17,370 --> 00:00:22,230
is create a new composition and call it mascot Trius.

5
00:00:22,550 --> 00:00:23,890
Five seconds is OK.

6
00:00:23,910 --> 00:00:28,270
And we click OK I will create here a shape player.

7
00:00:28,320 --> 00:00:32,300
I will create a rectangle shape to fill the whole composition.

8
00:00:32,480 --> 00:00:36,390
Well I have to do is just to double click and I learned something very new here.

9
00:00:36,410 --> 00:00:37,890
It's quite good.

10
00:00:37,920 --> 00:00:40,710
Now I want to create a mask on this shape player.

11
00:00:40,780 --> 00:00:48,450
What if you select for example the polygon instead of to create a shape you will use to create mask

12
00:00:48,630 --> 00:00:49,830
you highlighted.

13
00:00:49,830 --> 00:00:50,330
OK.

14
00:00:50,580 --> 00:00:53,530
So now everything as has also come over here.

15
00:00:53,580 --> 00:00:56,670
And click to create our polygon.

16
00:00:57,090 --> 00:00:58,070
Here it is.

17
00:00:58,080 --> 00:01:04,550
So let's pull up the contents we don't care what you animate them ask if it were done here.

18
00:01:04,570 --> 00:01:06,690
You always animate the path.

19
00:01:06,760 --> 00:01:08,260
This will elevate the mask.

20
00:01:08,260 --> 00:01:11,600
You can animate the feathering opacity and expansion if you like.

21
00:01:12,710 --> 00:01:20,290
If you click or mask path you have created a keyframe that is set for this shape of the mask or this

22
00:01:20,300 --> 00:01:25,900
state if you like I'm going to change the mask points because they're of the same color.

23
00:01:26,210 --> 00:01:29,050
As usual the yellow in this case it will work.

24
00:01:29,240 --> 00:01:29,840
Yes.

25
00:01:31,100 --> 00:01:38,360
So Yuuki for this mosque in this kind of shape and each point has its own position.

26
00:01:38,360 --> 00:01:40,800
Now let's come after one second OK.

27
00:01:41,030 --> 00:01:42,490
Was there the selection tool.

28
00:01:42,600 --> 00:01:47,640
Yes we you can click and drag the mask over here pretty easy.

29
00:01:48,050 --> 00:01:53,840
Now you created an animation where the masks move from one position to another position actually from

30
00:01:53,840 --> 00:01:56,850
one state to another state.

31
00:01:57,050 --> 00:02:01,990
And then after effects is doing the interoperation in between could come over here click inside.

32
00:02:02,010 --> 00:02:05,240
Let's try to change the points position.

33
00:02:05,340 --> 00:02:07,640
I'll click on the left one and take it to the right.

34
00:02:07,660 --> 00:02:08,090
OK.

35
00:02:08,270 --> 00:02:11,240
Click on the right one and take it to the left.

36
00:02:11,240 --> 00:02:12,740
As simple as this.

37
00:02:12,830 --> 00:02:15,110
Try to make an eye shape fight.

38
00:02:15,380 --> 00:02:21,720
So now if you jump to the first keyframe and you scrape through what is the interpellation that after

39
00:02:21,720 --> 00:02:24,340
effects has done in between the two states.

40
00:02:24,470 --> 00:02:31,070
If you scrub through not just what's happening is trying to preserve the animation for each point meaning

41
00:02:31,840 --> 00:02:38,580
let's select this point you can see it and if you come back over here it is the same one selected.

42
00:02:38,590 --> 00:02:45,380
So it's trying to move this point from this position from this date to the second state as simple as

43
00:02:45,380 --> 00:02:46,220
this.

44
00:02:46,220 --> 00:02:46,880
OK guys.

45
00:02:47,060 --> 00:02:50,820
And it does a very nice interpellation pretty logical by the way.

46
00:02:52,650 --> 00:02:55,950
If you decide OK I want to change here that's no problem.

47
00:02:56,050 --> 00:02:57,980
You can change them for example like this.

48
00:02:58,150 --> 00:03:03,620
And again you have a different interpellation and a different change in the mosque.

49
00:03:04,000 --> 00:03:06,140
Now I will do this too.

50
00:03:06,220 --> 00:03:08,510
There is the concept of the first Virtex.

51
00:03:08,590 --> 00:03:10,390
This is the main Virtex if you like.

52
00:03:10,390 --> 00:03:13,450
So over here we have the first Virtex on this point.

53
00:03:13,450 --> 00:03:19,720
And in the beginning we have the first Virtex on this point and this Jesus has come to the second state

54
00:03:19,840 --> 00:03:22,650
and exchange the first Virtex to this point.

55
00:03:22,660 --> 00:03:28,180
All you have to do is to right click go to mosque and ship path and here you have said this one to be

56
00:03:28,480 --> 00:03:30,610
the first Virtex here you are.

57
00:03:30,970 --> 00:03:38,620
So this is a state now because you change the Virtex script through aftereffects will always match the

58
00:03:38,620 --> 00:03:39,990
first verses.

59
00:03:40,000 --> 00:03:42,110
Here you are if you scrub.

60
00:03:42,250 --> 00:03:45,620
Look what's happening is going down and trying to match it.

61
00:03:45,670 --> 00:03:51,550
But in all the whole kind of animation or the whole interpellation has changed totally.

62
00:03:51,560 --> 00:03:54,000
It's pretty cool by the way to this point.

63
00:03:54,000 --> 00:04:00,520
Or let's take this point here Right-Click mosque and ship path and said this one to the first Virtex

64
00:04:00,790 --> 00:04:02,950
is going to match it with the other one.

65
00:04:02,950 --> 00:04:05,800
Here you are you can see it now very nicely.

66
00:04:05,800 --> 00:04:11,890
So actually this is the concept of animating masks just to create a state if you like how the points

67
00:04:11,980 --> 00:04:13,920
are positioned within the mosque.

68
00:04:13,930 --> 00:04:19,780
And then you jump in and you create another one including moving and rotating.

69
00:04:19,790 --> 00:04:21,700
Let's see another option here with the ship.

70
00:04:21,800 --> 00:04:23,360
So we have here a polygon.

71
00:04:23,360 --> 00:04:29,470
Let's go to the next keyframe and click and say OK we want to reset it to a rectangle.

72
00:04:29,480 --> 00:04:30,610
I click OK.

73
00:04:31,020 --> 00:04:34,770
And that is here we have one two three four points.

74
00:04:34,820 --> 00:04:35,270
OK.

75
00:04:35,270 --> 00:04:38,850
If we come back here we have five points here.

76
00:04:38,870 --> 00:04:44,930
So after effect is going to interpret it as find a certain position for the missing point from over

77
00:04:44,930 --> 00:04:45,560
here.

78
00:04:45,710 --> 00:04:48,150
It's actually Zappy at one frame before you can see it.

79
00:04:48,210 --> 00:04:49,960
Here then comes here.

80
00:04:50,060 --> 00:04:51,380
It has disappeared.

81
00:04:51,560 --> 00:04:52,700
This is pretty cool.

82
00:04:52,710 --> 00:04:57,270
And you must appreciate this intelligence is really very nice.

83
00:04:58,370 --> 00:05:02,280
If you come to the federal You can also animate the fact that I will keyframe over here.

84
00:05:02,510 --> 00:05:08,060
But the feather at 0 coming over to the next state or in between if you like and you increase the weather

85
00:05:08,060 --> 00:05:13,850
let's make a big value and then you have the feathering being animated like any other property.

86
00:05:13,850 --> 00:05:16,720
No big deal about it could do this.

87
00:05:16,760 --> 00:05:22,790
And then the opacity you know very well you can animate it from 0 percent to 100 percent.

88
00:05:22,860 --> 00:05:25,150
So you can only make the mask expansion.

89
00:05:25,160 --> 00:05:26,850
Let's create a keyframe here.

90
00:05:27,050 --> 00:05:33,230
And the value is 0 0 for example come to the other side and let's reduce the value just for the example.

91
00:05:33,260 --> 00:05:34,420
And it's pretty neat.

92
00:05:34,530 --> 00:05:39,590
The expansion will have a lot of use later on when you're doing mask tracking for example.

93
00:05:39,660 --> 00:05:45,810
So this was about how to animate masks and the concept of the interpellation that aftereffects does

94
00:05:46,140 --> 00:05:48,480
and the concept of the first vertex.

95
00:05:48,540 --> 00:05:50,190
Thank you very much for listening.

96
00:05:50,190 --> 00:05:55,260
I hope this was extremely beneficial for you and please review this lecture a couple of times.

97
00:05:55,260 --> 00:05:59,680
So you are very comfortable with mask the mission and the way it happens.

98
00:05:59,790 --> 00:06:01,110
I would see you in the next lecture.
