00:00:00,920 --> 00:00:07,120
Hi guys in this lecture we are going to use animation for masks using the opacity of the mosque.

2
00:00:07,120 --> 00:00:12,520
And it's a bit tricky but I want to show you how to use it and how to create these kinds of video mats

3
00:00:12,580 --> 00:00:14,210
that are very useful later on.

4
00:00:14,260 --> 00:00:17,590
Let's take up our video composition over here and duplicate.

5
00:00:17,590 --> 00:00:22,270
We have video to Tejan in into video Mott's opacity.

6
00:00:22,390 --> 00:00:24,760
So you know very well what is happening.

7
00:00:25,030 --> 00:00:26,730
I would double click to open.

8
00:00:26,830 --> 00:00:29,850
I will come to the name here and say close other comps.

9
00:00:29,890 --> 00:00:34,440
So I have only this game that is opened the render is not on comp.

10
00:00:34,510 --> 00:00:37,660
Now I want to change the kind of animation I'm doing here.

11
00:00:37,660 --> 00:00:39,240
I have animated the ship.

12
00:00:39,280 --> 00:00:39,960
That's very good.

13
00:00:39,960 --> 00:00:42,520
Let's come here and read all this keyframes.

14
00:00:42,520 --> 00:00:46,870
So we have zero animation but what do we have if you come to the layer.

15
00:00:46,870 --> 00:00:49,800
Here we have the capacity.

16
00:00:49,930 --> 00:00:54,170
Now there is a small trick about that opacity the opacity can go to zero.

17
00:00:54,310 --> 00:00:58,660
Unfortunately for the first layer it will clear everything else.

18
00:00:58,760 --> 00:01:00,220
Let's put it back to 100.

19
00:01:00,220 --> 00:01:05,580
But for the second layer if you open opacity it will work very fine for you.

20
00:01:05,640 --> 00:01:08,590
You see you have you can darken it or make it opaque.

21
00:01:08,710 --> 00:01:09,830
And this is transparent.

22
00:01:09,970 --> 00:01:15,830
The trick here is if you want to use the first layer opacity we need to create a layer before and we

23
00:01:15,840 --> 00:01:17,030
are hided around here.

24
00:01:17,140 --> 00:01:19,000
So it becomes the major layer.

25
00:01:19,130 --> 00:01:25,820
I would select the solid layer and click and make a small rectangle here and take the mask six now and

26
00:01:25,960 --> 00:01:31,780
put it on top and say I would rename it to hidden actually.

27
00:01:31,780 --> 00:01:33,600
I would lock it later on a press enter.

28
00:01:33,820 --> 00:01:35,390
So now let's do this more trick.

29
00:01:35,410 --> 00:01:41,660
The first mask I'm going to inverted and then the second mask here I'm going to put it subsect.

30
00:01:41,710 --> 00:01:46,320
So it's good except this one we are going to lock so we don't touch.

31
00:01:46,370 --> 00:01:48,350
Now we like fiddle with the opacity.

32
00:01:48,370 --> 00:01:53,500
Not as I have it nontransparent transparent the same for all the other layers.

33
00:01:53,620 --> 00:01:54,210
Cool.

34
00:01:54,340 --> 00:02:00,850
So let's come to one second and we want them all nontransparent so I keyframe the past to here come

35
00:02:01,150 --> 00:02:05,170
to this one keyframe the opacity or so I would come to opacity.

36
00:02:05,180 --> 00:02:12,860
Copy go to the next mass based opacity go to the third mask based again the first mask base and paste

37
00:02:12,880 --> 00:02:13,500
again.

38
00:02:13,500 --> 00:02:14,650
Now I stick light.

39
00:02:14,650 --> 00:02:17,800
Bless you and you have the opacity all keyframe.

40
00:02:18,130 --> 00:02:19,690
I will come to the beginning here.

41
00:02:19,980 --> 00:02:22,000
Take the opacity to zero.

42
00:02:22,000 --> 00:02:28,850
Now I will copy the opacity Control-C come to the second mass control V it can do the third mass control.

43
00:02:28,890 --> 00:02:30,270
You see it's happening.

44
00:02:30,400 --> 00:02:32,410
This one called Revie and Contrave.

45
00:02:32,440 --> 00:02:34,420
I am so lazy and I love it.

46
00:02:34,420 --> 00:02:36,010
Now not what's happening.

47
00:02:36,010 --> 00:02:40,420
The opacity is playing its role but of course we're not going to leave it like this.

48
00:02:40,410 --> 00:02:44,050
What you'll want to do is first of all to make it a bit shorter.

49
00:02:44,340 --> 00:02:48,010
OK then take the keyframes and start moving them on the side.

50
00:02:48,250 --> 00:02:50,260
Just like this you can put the timing you want.

51
00:02:50,260 --> 00:02:55,620
I don't know if I am doing good timing by the way but we will test and see OK.

52
00:02:55,650 --> 00:02:57,900
Let's run our own emission.

53
00:02:57,950 --> 00:02:59,930
Could you see what that appearing fine.

54
00:02:59,960 --> 00:03:02,690
So we created video might opacity.

55
00:03:02,720 --> 00:03:06,500
Let's take the video clip create a new composition with the video clip.

56
00:03:06,650 --> 00:03:09,600
Take our latest one which is video posted.

57
00:03:09,610 --> 00:03:11,170
Drop it on top.

58
00:03:11,380 --> 00:03:12,710
Running low on ammunition.

59
00:03:12,740 --> 00:03:19,140
And here we are we have it fantastically working right click on the mask if you like transform and see

60
00:03:19,140 --> 00:03:25,060
fit to come up and you have a very nice animation here with the opacity.

61
00:03:25,250 --> 00:03:28,460
And I have seen this in very many professional sites.

62
00:03:28,460 --> 00:03:35,990
Now of course what we have to do is to come out of opacity go to composition say to render you come

63
00:03:35,990 --> 00:03:43,210
to the best setting if we don't need messaging we wanted best and we got the last less you will actually

64
00:03:43,210 --> 00:03:47,350
turn it into a quick time Aggi plus Alfar that's very easy.

65
00:03:47,360 --> 00:03:52,960
And we have the mission is special 100 percent we're happy from everything we know what is going to

66
00:03:52,960 --> 00:03:55,800
render and render it in two seconds.

67
00:04:03,130 --> 00:04:06,100
Right click and import file.

68
00:04:06,180 --> 00:04:10,800
Now it's called Video Martes with something else.

69
00:04:10,830 --> 00:04:16,370
Now it's video Mott's opacity with a mistake in spelling but it's ok.

70
00:04:16,380 --> 00:04:17,880
I think you would forgive me.

71
00:04:17,960 --> 00:04:18,230
Good.

72
00:04:18,270 --> 00:04:19,760
So we have it here.

73
00:04:19,920 --> 00:04:22,010
Let's take our video.

74
00:04:22,140 --> 00:04:29,010
Create a new camp and take our video motet and drop it on top.

75
00:04:29,120 --> 00:04:30,070
And here you are.

76
00:04:30,110 --> 00:04:31,530
You have it at 100 percent.

77
00:04:31,540 --> 00:04:32,290
Let's play it.

78
00:04:32,330 --> 00:04:40,050
We think sometimes to render up we can come back here we see transform and fit to come up.

79
00:04:40,070 --> 00:04:44,960
So now you have your mat video that you can put anywhere you want.

80
00:04:44,960 --> 00:04:46,530
Thank you very much for listening.

81
00:04:46,550 --> 00:04:53,150
I hope this section was very useful to what you can do and what I do sometimes if I have time free and

82
00:04:53,150 --> 00:04:59,570
I feel like it I will go and create so many of these in many many fashions with firework stories like

83
00:04:59,570 --> 00:05:03,780
this and so on and just store them as my video library.

84
00:05:03,830 --> 00:05:04,970
It's very useful.

85
00:05:04,970 --> 00:05:08,770
Actually I will use one over 100 when there is a need.

86
00:05:08,780 --> 00:05:14,530
But the ideas that are there are very good and they helped me create even more and more.

87
00:05:14,780 --> 00:05:15,710
Thanks for listening.

88
00:05:15,710 --> 00:05:18,510
I'll see you in the next section or in the next lecture.
