00:00:01,040 --> 00:00:09,490
As you said guys rotoscoping is separating an object an element or a subject if you like from its background.

2
00:00:09,650 --> 00:00:14,870
And then you can change the background and give it any other background you did like this very practical

3
00:00:14,870 --> 00:00:17,390
when you didn't shoot in front of a green screen.

4
00:00:18,870 --> 00:00:22,770
If you want to follow along with me please open the project file.

5
00:00:22,920 --> 00:00:29,240
Rotoscoping started the AP and in this project you have four videos here.

6
00:00:29,470 --> 00:00:31,970
You are going to try to work or most of them.

7
00:00:32,110 --> 00:00:36,160
The first and easiest one is the man walking in the desert here.

8
00:00:36,500 --> 00:00:44,130
If you just the other guy walking in the desert and then you want to separate this guy from the background

9
00:00:44,220 --> 00:00:45,980
which is the desert very dull.

10
00:00:45,980 --> 00:00:50,690
I put him like walking in the rain or at the fire or whatever you like.

11
00:00:50,720 --> 00:00:53,640
I landed on one that is pretty complicated.

12
00:00:53,650 --> 00:00:59,760
Very nice is to separate the leaves from the blurred background and not as there is quite some work

13
00:00:59,760 --> 00:01:04,380
here to do because the leaves on the background are almost human of course.

14
00:01:04,380 --> 00:01:08,350
The technique I would show you would even allow you to do this one very easily.

15
00:01:08,490 --> 00:01:13,380
Then you have the photographer here a video we have already used and it's very interesting to use the

16
00:01:13,380 --> 00:01:15,910
Schwann because she has some hair here.

17
00:01:15,950 --> 00:01:23,330
Delegate you know that is that you want to keep after all the Skopec So usually when you are at a scoping

18
00:01:23,330 --> 00:01:28,410
you don't want to use the whole video shot like for example there is nothing here and here.

19
00:01:28,430 --> 00:01:30,630
You don't want that for example.

20
00:01:30,890 --> 00:01:33,410
So you can decide where to start your footage.

21
00:01:33,410 --> 00:01:38,640
For example you can start the footage from here and put the important.

22
00:01:38,900 --> 00:01:45,360
Then go to whatever you want to and for example over here and put the outpoint.

23
00:01:45,620 --> 00:01:51,470
Now you have defined your footage defining your footage here is much better than creating a composition

24
00:01:51,560 --> 00:01:55,310
was the whole footage start me inside the composition.

25
00:01:55,310 --> 00:02:00,650
This is a much better way because you have limited your footage and you know exactly what you're working

26
00:02:00,650 --> 00:02:01,260
on.

27
00:02:01,640 --> 00:02:07,280
So now after working on the footage panel you can click and drag the footage to create a new composition

28
00:02:07,850 --> 00:02:11,920
and you know here you have the composition exactly like your footage.

29
00:02:12,410 --> 00:02:13,090
As close.

30
00:02:13,110 --> 00:02:17,690
The footage palette to the being in after effects.

31
00:02:17,750 --> 00:02:20,670
The best way is to use the Rotto brush tool.

32
00:02:20,880 --> 00:02:24,310
If you click on it you have Rotto brush and a fine edge.

33
00:02:24,370 --> 00:02:26,490
Two very powerful tools.

34
00:02:26,690 --> 00:02:34,150
Let's start with the rotor approach which will allow us to select our subject or the foreground and

35
00:02:34,220 --> 00:02:40,810
later on the refined edge will allow us to refine the edges as simple as this.

36
00:02:40,850 --> 00:02:45,990
We start with a lot of brush but you're not as in the composition panel here.

37
00:02:46,010 --> 00:02:52,330
There is nothing I can't use the brush use a lot of brush in the layer palette so to open the panel

38
00:02:52,400 --> 00:02:57,240
of course you know you click and here you are you are in the last panel.

39
00:02:57,290 --> 00:02:59,990
Now this is the Rotto brush tool.

40
00:03:00,310 --> 00:03:03,280
When it is green it's used to do the selection.

41
00:03:03,380 --> 00:03:08,590
If you press alt or option on the Mac it will become red and you have a negative sign.

42
00:03:08,600 --> 00:03:14,460
Now it is used to de-select foreground or background to adjust the size.

43
00:03:14,480 --> 00:03:21,200
You can press control of command on the Mac and go left or right to make it bigger or smaller.

44
00:03:21,500 --> 00:03:23,790
For example I make it this size here.

45
00:03:23,830 --> 00:03:25,560
You're not quite practical.

46
00:03:25,820 --> 00:03:31,190
Now the first thing to do is to set your timeline indicated at the beginning of your footage in the

47
00:03:31,200 --> 00:03:32,150
composition panel.

48
00:03:32,150 --> 00:03:36,860
Of course you notice that moving in sync here with the their palette.

49
00:03:37,010 --> 00:03:39,060
And then you start doing the selection.

50
00:03:39,080 --> 00:03:39,860
What do you want to do.

51
00:03:39,890 --> 00:03:42,520
Is the best selection possible for now.

52
00:03:42,530 --> 00:03:44,240
So I click and drag.

53
00:03:44,420 --> 00:03:47,210
You are trying to select everything.

54
00:03:47,420 --> 00:03:48,860
You don't have to be very meticulous.

55
00:03:48,860 --> 00:03:51,060
Don't go too much on the borders.

56
00:03:51,120 --> 00:03:53,420
No something like this will be OK.

57
00:03:53,720 --> 00:03:54,080
Fine.

58
00:03:54,080 --> 00:03:55,100
I love this work.

59
00:03:55,100 --> 00:03:57,860
So usually I go very nicely.

60
00:03:57,860 --> 00:04:00,260
One by Byron and I love the result.

61
00:04:00,290 --> 00:04:07,070
Now you have done your first selection and you're not this you have a purple line all around the purple

62
00:04:07,070 --> 00:04:07,440
line.

63
00:04:07,460 --> 00:04:15,980
Well defined the foreground or your subject whatever is inside the glows purple line it is your foreground

64
00:04:16,040 --> 00:04:18,920
and whatever is outside it is your background.

65
00:04:18,980 --> 00:04:23,600
You can click on your compositional panel already and see the results.

66
00:04:23,600 --> 00:04:30,110
You notice that the background does appear and what I've it was that within the purple line it's your

67
00:04:30,170 --> 00:04:35,890
finger but you're not this we need to you know adjusted a bit over here.

68
00:04:35,890 --> 00:04:38,870
Let's go back here and the way I like working.

69
00:04:38,890 --> 00:04:42,690
First of all I like to look at the big elements for example.

70
00:04:42,910 --> 00:04:45,780
We missed you know a big part of the address here.

71
00:04:45,940 --> 00:04:48,270
So I'm going to click and start adding.

72
00:04:48,480 --> 00:04:49,240
OK.

73
00:04:49,240 --> 00:04:54,480
Notice how the line has moved and I'm going to do another one just over here.

74
00:04:54,490 --> 00:05:00,540
Better yet is to press alt point whatever you want to select and roll the mouse button.

75
00:05:00,610 --> 00:05:03,610
So you know exactly what you want to select.

76
00:05:03,670 --> 00:05:07,510
So I press control here to make the brush a bit smaller.

77
00:05:07,510 --> 00:05:09,970
Come over here and select this piece.

78
00:05:10,150 --> 00:05:11,190
I'm happy with it.

79
00:05:11,200 --> 00:05:14,230
It's very nice that you are very meticulous.

80
00:05:14,470 --> 00:05:19,930
If you're past the spacebar move it will show you the results so you can come and you know see exactly

81
00:05:20,470 --> 00:05:23,150
what has been removed and was staying here.

82
00:05:23,150 --> 00:05:23,890
Here you are.

83
00:05:23,920 --> 00:05:25,100
Very nice.

84
00:05:25,150 --> 00:05:34,460
Now press over here and we know that you want to take the hair later on we will refine it but it's ok.

85
00:05:34,750 --> 00:05:35,650
I don't like it very much.

86
00:05:35,650 --> 00:05:36,810
I'm going to remove it.

87
00:05:36,820 --> 00:05:42,550
You see I press alt or option on the Mac now and the minus I removed that will work is that the fine

88
00:05:42,550 --> 00:05:44,370
tool to get this word right.

89
00:05:44,620 --> 00:05:44,840
Good.

90
00:05:44,860 --> 00:05:51,740
You want now to use the zoom in that's on or capture the Mac and photos slash video.

91
00:05:52,020 --> 00:05:53,670
Let's go to the face over here.

92
00:05:53,680 --> 00:05:58,420
I press alt zoom me in and simply try to take as much as I can.

93
00:05:58,510 --> 00:06:00,510
Now I like to be meticulous.

94
00:06:00,520 --> 00:06:04,570
I like to be very precise and it would save you a lot of problems.

95
00:06:04,570 --> 00:06:11,210
And also your work will look much better and much nicer you know not like a beginner.

96
00:06:12,170 --> 00:06:13,730
Over here I need to adjust.

97
00:06:13,750 --> 00:06:20,590
I would roll the mouse press art to make it negative and then remove this bag on from here.

98
00:06:20,830 --> 00:06:21,320
OK.

99
00:06:21,320 --> 00:06:27,210
And another time up this space bar and goes down.

100
00:06:27,490 --> 00:06:28,160
Yes.

101
00:06:28,210 --> 00:06:30,970
And remove this background from here.

102
00:06:31,420 --> 00:06:32,880
It's working very fine.

103
00:06:33,070 --> 00:06:34,950
I want to adjust this one even more.

104
00:06:35,980 --> 00:06:36,730
OK.

105
00:06:37,050 --> 00:06:46,430
Here you are as good down and Helier fine and maybe maybe you would want to remove this duct.

106
00:06:46,470 --> 00:06:49,060
It's working a bit too much.

107
00:06:49,210 --> 00:06:49,480
OK.

108
00:06:49,500 --> 00:06:51,200
This is being very aggressive.

109
00:06:51,240 --> 00:06:54,180
Let's press art and forward slash to see.

110
00:06:54,180 --> 00:06:56,990
Let's go to our composition and not this well.

111
00:06:57,000 --> 00:06:57,720
It's OK.

112
00:06:57,720 --> 00:06:59,670
It's not bad maybe here we need to look at it.

113
00:06:59,700 --> 00:07:03,300
And the camera does take any piece we don't want.

114
00:07:03,340 --> 00:07:09,890
I press I'll zoom in and here I want to remove this piece just over here.

115
00:07:10,230 --> 00:07:12,030
Here you are again.

116
00:07:14,100 --> 00:07:17,870
So you did the first selection do you just started.

117
00:07:18,120 --> 00:07:24,780
And from this selection you're going to start refining the edges and the rotoscoping the whole two seconds

118
00:07:24,780 --> 00:07:31,050
or three seconds that you have in the next lecture you start using the define edge tool to work on the

119
00:07:31,050 --> 00:07:31,720
hair.

120
00:07:32,040 --> 00:07:32,570
Thank you.

121
00:07:32,650 --> 00:07:33,890
I'll see you in the next lecture.
