1
00:00:01,350 --> 00:00:09,030
Guys and will come to Musk's this is a very important section is the section that will lead you to work

2
00:00:09,030 --> 00:00:15,210
with videos and even motion graphics the way you would like and you need to practice practice your hand

3
00:00:15,240 --> 00:00:23,280
practice visual and try always to perfect your methods and create your own the project file for this

4
00:00:23,280 --> 00:00:25,880
section is working with masks.

5
00:00:26,130 --> 00:00:27,370
You don't need to open it now.

6
00:00:27,420 --> 00:00:32,300
You can open it at the end of the section and see exactly how we have done everything.

7
00:00:32,580 --> 00:00:34,670
We are going to start from scratch.

8
00:00:34,690 --> 00:00:37,920
Import our videos and start working on Musk's.

9
00:00:37,950 --> 00:00:42,930
So let's go right to the project panel right click and import file.

10
00:00:43,980 --> 00:00:46,470
For this section we need that specific files.

11
00:00:46,740 --> 00:00:52,690
I want all the files that Swan And we need the reverse.

12
00:00:52,740 --> 00:00:53,940
So I press control.

13
00:00:53,960 --> 00:00:55,230
I get the reverse.

14
00:00:55,350 --> 00:01:00,330
And then of course we'll click Import to bring in the file.

15
00:01:00,530 --> 00:01:03,910
We can use the cut 33 16 to start our work.

16
00:01:03,910 --> 00:01:08,710
Click on track and to create a position from this video.

17
00:01:08,720 --> 00:01:12,930
So what are masks masks will mask your layer.

18
00:01:12,950 --> 00:01:17,080
It will show or hide certain parts of your hair to create masks.

19
00:01:17,210 --> 00:01:21,240
Use the ship tools and the pen tool.

20
00:01:21,260 --> 00:01:23,490
Let's start with the ship to here.

21
00:01:23,590 --> 00:01:26,790
Let's create a simple mask using the ellipse.

22
00:01:26,870 --> 00:01:31,850
First of all if you don't select your Land Of course you'll be creating a shape here.

23
00:01:31,850 --> 00:01:34,130
So I will undo that to create a mask.

24
00:01:34,150 --> 00:01:38,450
You need to select your layer and then click and drag to create a mask.

25
00:01:38,570 --> 00:01:44,510
For example click in the middle and notice that everything has disappeared because the only thing that

26
00:01:44,510 --> 00:01:48,080
are going to appear by default is what's inside the mask.

27
00:01:48,380 --> 00:01:53,510
So I press shift and control and drag out to create a perfect circle.

28
00:01:53,670 --> 00:01:59,340
If you remember you can use the space bar or so to take it down or to move it around to put it over.

29
00:01:59,340 --> 00:02:04,980
The first thing you do after the Create the mask is to click on the time indicator and scrap through

30
00:02:05,430 --> 00:02:11,150
to see if your subject that you are trying to mask all the area is always included within the mask.

31
00:02:11,160 --> 00:02:12,130
In our case here we are.

32
00:02:12,160 --> 00:02:17,430
Call is not the so you created a mask from the surface.

33
00:02:17,790 --> 00:02:18,880
Let's look at the shape there.

34
00:02:18,910 --> 00:02:20,620
Here we notice we have masks.

35
00:02:20,880 --> 00:02:23,860
And of course it's masks so you can have very many.

36
00:02:24,270 --> 00:02:30,540
And we created mask one you can rename must gwon you press enter and you give it another name for example.

37
00:02:30,700 --> 00:02:35,390
Got had Ereli people renamed them.

38
00:02:35,400 --> 00:02:41,220
Unless you have something complicated let's destroyed them masks and you not is that you have four properties

39
00:02:41,220 --> 00:02:43,850
here that you can animate pretty interesting.

40
00:02:44,660 --> 00:02:50,380
An art so you have the attribute of the mosque which you can have I add subtract and so on would see

41
00:02:50,380 --> 00:02:54,720
that it now the first thing I went through is inverted.

42
00:02:54,740 --> 00:02:59,770
You notice that the mask that you have created is showing only what's inside the mask.

43
00:02:59,780 --> 00:03:04,310
So this is the control of the mask and inside that's what we are going to see.

44
00:03:04,340 --> 00:03:08,870
But if you click inverted you'll see everything outside the mask.

45
00:03:08,960 --> 00:03:10,120
Makes sense to you.

46
00:03:10,280 --> 00:03:15,450
Vaizey mask Pathi it is the shape of the mask.

47
00:03:15,470 --> 00:03:17,510
In fact it's a path and you can.

48
00:03:17,520 --> 00:03:21,530
And he made that you can come over and change the shape or show this.

49
00:03:21,530 --> 00:03:28,310
Now you click on shape and the top left right and bottom are the coordinates of the mask within the

50
00:03:28,310 --> 00:03:29,330
composition.

51
00:03:29,330 --> 00:03:32,740
If you turn for example either right here and you click OK.

52
00:03:32,830 --> 00:03:35,800
You notice that you distorted the mask a bit.

53
00:03:35,900 --> 00:03:41,380
So these are the coordinates of the corners of the mask.

54
00:03:41,540 --> 00:03:47,950
You can choose the units here which we usually never do and you is that the mask shape you can reset

55
00:03:47,980 --> 00:03:51,650
it for example to elipse if you like to it's an ellipse already.

56
00:03:51,660 --> 00:03:54,100
So let's reset it to a rectangle.

57
00:03:54,240 --> 00:03:55,340
So click OK.

58
00:03:55,350 --> 00:03:57,630
It has turned it into a rectangle.

59
00:03:57,940 --> 00:03:59,520
I'll get back to elipse.

60
00:03:59,580 --> 00:04:01,390
You are fine.

61
00:04:01,590 --> 00:04:08,490
Now there is the mask feathering the mask feathering just feather the mask meaning it to create a blurred

62
00:04:08,550 --> 00:04:10,250
area around the mosque.

63
00:04:10,320 --> 00:04:12,080
You see how it's blurred.

64
00:04:12,270 --> 00:04:14,820
You can only get it positive outside the mask.

65
00:04:14,820 --> 00:04:16,550
So it's pretty cool like this.

66
00:04:16,560 --> 00:04:20,040
See very many videos and movies that use this feature.

67
00:04:20,040 --> 00:04:24,370
You can also get further on on the presented here.

68
00:04:24,780 --> 00:04:29,540
Or you can feather on the vertical only depending on what you want to do.

69
00:04:29,630 --> 00:04:30,150
OK.

70
00:04:30,360 --> 00:04:37,350
So I will undo this and keep it that that there is the mask opacity the mask capacity will play on the

71
00:04:37,350 --> 00:04:40,210
opacity of what's inside the mask.

72
00:04:40,380 --> 00:04:42,680
For example as 0 you see nothing.

73
00:04:42,690 --> 00:04:45,590
Of course it's zero opacity at 100.

74
00:04:45,600 --> 00:04:47,510
You see it at full capacity.

75
00:04:47,550 --> 00:04:49,700
Now there is the mosque expansion here for this.

76
00:04:49,710 --> 00:04:52,540
I'm going to put the mask feathering to zero.

77
00:04:52,680 --> 00:04:56,610
You can expand your mask meaning make it bigger.

78
00:04:56,820 --> 00:05:00,090
This is pretty useful if you use it with the feathering.

79
00:05:00,210 --> 00:05:05,640
OK guys you can also shrink it if you are inside.

80
00:05:05,710 --> 00:05:09,310
So this is all about mask is pretty easy.

81
00:05:09,310 --> 00:05:15,010
You put a mask and you can inverted or keep it the way it is and you have the properties that later

82
00:05:15,010 --> 00:05:16,710
on we can start any meat.

83
00:05:16,960 --> 00:05:21,040
Thank you for listening and move on to the next lecture more about masks.
