1
00:00:38,283 --> 00:00:41,049
Welcome back to part 3, and this time
we're going to be looking at

2
00:00:41,349 --> 00:00:45,333
post-production with the green screen
and how to edit it into your sequence.

3
00:00:47,899 --> 00:00:49,666
For this example,

4
00:00:49,666 --> 00:00:52,399
we're going to be using Premiere Pro
but across different

5
00:00:52,749 --> 00:00:57,166
editing softwares, the names of tools
and the process will remain similar.

6
00:00:58,366 --> 00:01:01,633
First up, we're going to import a footage,
which I've downloaded

7
00:01:01,633 --> 00:01:02,899
from the stock website.

8
00:01:02,899 --> 00:01:07,366
Drag that onto our timeline,
and this one is our backing.

9
00:01:07,399 --> 00:01:12,099
So this one's going to be background
subject will be pasted on top of.

10
00:01:12,499 --> 00:01:15,166
And over here we've got the subject,
which we're going to be putting

11
00:01:15,166 --> 00:01:18,099
into the background
that I've just shown you.

12
00:01:21,199 --> 00:01:24,132
Sometimes when you import stock
footage, it's not cropped

13
00:01:24,282 --> 00:01:28,116
correctly, so you can just correct that by
double clicking and stretching out.

14
00:01:32,716 --> 00:01:33,499
And then move it

15
00:01:33,499 --> 00:01:36,666
on to layer 2 of the timeline.

16
00:01:36,666 --> 00:01:40,032
So then the bottom layer
clip of the women on the stage

17
00:01:40,182 --> 00:01:43,816
that's going to be prominent on the clip
when we take the green out.

18
00:01:45,799 --> 00:01:48,166
Once we've done that,
we open the 'effects' tab found

19
00:01:48,166 --> 00:01:51,432
at the top of the screen there
and search in this bar for 'Ultra Key'.

20
00:01:53,366 --> 00:01:54,849
And drag that over

21
00:01:54,849 --> 00:01:57,332
onto the top layer,
which is of the businesswoman.

22
00:01:58,532 --> 00:02:00,816
And then over here,
we've got the 'key colour' setting,

23
00:02:00,966 --> 00:02:04,299
we want to select the color selection tool

24
00:02:04,682 --> 00:02:06,849
and we click on the background
to remove the green.

25
00:02:08,182 --> 00:02:11,782
That'll work whether it's blue or white,

26
00:02:12,166 --> 00:02:15,416
but in this case, it's obviously the green
and we're turning that transparent.

27
00:02:16,316 --> 00:02:19,532
To fit this businesswoman into the scene,
we need to re-scale her

28
00:02:19,532 --> 00:02:21,599
because otherwise
she's just going to be taking up

29
00:02:22,549 --> 00:02:24,599
the entire space.

30
00:02:24,999 --> 00:02:28,249
So this
the woman on the stage is walking out.

31
00:02:28,266 --> 00:02:31,416
So we want to make sure
that the businesswoman is scaled

32
00:02:31,416 --> 00:02:33,849
to fit with that scene.

33
00:02:33,849 --> 00:02:37,116
So we do that again
by double clicking and just correcting it

34
00:02:37,449 --> 00:02:39,599
until we think it's suitable.

35
00:02:40,966 --> 00:02:42,949
Sometimes be helped by zooming in,

36
00:02:42,949 --> 00:02:45,932
which you can find in the corner there.

37
00:02:46,549 --> 00:02:49,149
But once we've done that, as we can see,
there's a bit of an outline

38
00:02:49,149 --> 00:02:53,799
around the businesswoman and see that
white kind of shade on her calf.

39
00:02:55,182 --> 00:02:57,915
And you can also see it around her
arm and face.

40
00:02:59,049 --> 00:03:01,149
So that will happen
quite a lot when you're

41
00:03:01,149 --> 00:03:05,165
green screening, as will quite a lot
of other imperfections, but that's OK.

42
00:03:05,165 --> 00:03:09,815
We can go over here and see the 'Effect Controls' tab and go into matte generation.

43
00:03:11,299 --> 00:03:11,749
'Pedestal' at the bottom,

44
00:03:11,749 --> 00:03:14,749
there is usually the most useful
I've found.

45
00:03:19,165 --> 00:03:21,599
Sometimes
'highlight' can make a big difference too.

46
00:03:21,699 --> 00:03:24,899
This is predominantly useful
when you're using stock footage

47
00:03:24,899 --> 00:03:26,799
because obviously the two scenes

48
00:03:26,799 --> 00:03:29,249
that you're trying to edit together,
were not filmed the same.

49
00:03:29,999 --> 00:03:31,799
Next up, we want to open 'matte cleanup'.

50
00:03:31,799 --> 00:03:36,065
The most useful tool I've found here is
'choke', which just crops out the outside.

51
00:03:36,065 --> 00:03:38,882
As we can see
here, I'll scale it all the way up

52
00:03:38,882 --> 00:03:41,699
just so you can see what it does.

53
00:03:42,682 --> 00:03:44,815
So we're just going to reset that

54
00:03:44,815 --> 00:03:48,049
and then gently nudge it up
so that she doesn't lose half of her face,

55
00:03:48,199 --> 00:03:50,782
but that she loses that white outline
around her.

56
00:03:51,232 --> 00:03:54,799
Well, as you can see around
the hair is a bit of a hard edge there,

57
00:03:55,165 --> 00:03:56,332
but we can correct that as well.

58
00:03:56,332 --> 00:03:59,949
So we go in to 'soften' and again,
just gently nudge that up,

59
00:04:00,232 --> 00:04:02,949
so as to not ruin the footage
by trying to correct it.

60
00:04:03,915 --> 00:04:04,649
But if you do make

61
00:04:04,649 --> 00:04:09,415
any mistakes, as we saw earlier,
there is a refresh button

62
00:04:09,415 --> 00:04:11,015
just on the side.

63
00:04:11,632 --> 00:04:15,232
So here we're going to de-saturate
the green screen footage

64
00:04:15,748 --> 00:04:18,232
because that was lit in an environment

65
00:04:18,232 --> 00:04:20,365
that is not this environment
from the background.

66
00:04:21,298 --> 00:04:23,298
So we're going to take out that color
from there,

67
00:04:23,598 --> 00:04:29,148
but we can put that back in over here so
as to match with the background footage.

68
00:04:29,148 --> 00:04:32,298
It's taking away
the light that came with it

69
00:04:32,298 --> 00:04:34,398
and replacing it
with lighting that we want.

70
00:04:34,965 --> 00:04:38,715
So as we can see, it's
put a bit more color in the cheeks there,

71
00:04:39,265 --> 00:04:43,048
which fits well because this woman
on the side here is lit very strongly.

72
00:04:44,382 --> 00:04:48,365
And there's a lot of hues
of yellow and pink.

73
00:04:49,298 --> 00:04:52,482
So over here, we can correct that
by upping the temperature more towards

74
00:04:52,482 --> 00:04:53,432
orange.

75
00:04:53,432 --> 00:04:57,248
We're trying to match that harsh
lighting on the presenters face.

76
00:04:58,698 --> 00:05:01,498
And then we can go into highlights
and do the same thing

77
00:05:01,732 --> 00:05:04,948
so as to try and replicate light,
that's bouncing off the presenters

78
00:05:05,182 --> 00:05:06,248
head there.

79
00:05:09,265 --> 00:05:11,798
If we were to watch that back, it's
now more believable

80
00:05:11,798 --> 00:05:14,515
that that scene is one piece of footage.

81
00:05:18,082 --> 00:05:19,365
Except that she's presenting

82
00:05:19,365 --> 00:05:23,182
just before the actual presenter
walks out onto the stage.

83
00:05:23,482 --> 00:05:25,998
But we can correct that in the timeline
here by syncing that

84
00:05:28,932 --> 00:05:31,148
up, by moving it to where she walks out

85
00:05:31,148 --> 00:05:35,115
and then removing the footage
that we don't need.

86
00:05:39,581 --> 00:05:42,065
So now the businesswoman
is presenting the speaker,

87
00:05:42,281 --> 00:05:45,215
right as the speaker walks out.

88
00:05:49,081 --> 00:05:50,448
And if we just take out

89
00:05:50,448 --> 00:05:53,115
all that other footage that we don't need,

90
00:05:53,848 --> 00:05:56,548
then we've got quite a nice short,
coherent clip

91
00:05:57,081 --> 00:06:00,915
of a woman presenting a speaker
on stage to deliver a presentation.

92
00:06:04,965 --> 00:06:07,865
So as
I said, as we're using stock footage,

93
00:06:07,865 --> 00:06:09,515
the lighting doesn't quite match up,

94
00:06:09,515 --> 00:06:12,698
but this won't be a problem when you're
filming the footage for yourself.

95
00:06:13,515 --> 00:06:16,215
So over here
we can save and export when we're ready.

96
00:06:16,398 --> 00:06:19,015
And that's how you edit a green screen
in post-production.

97
00:06:20,015 --> 00:06:23,015
Green screens are helpful
and can advance your skills professionally

98
00:06:23,015 --> 00:06:23,781
and creatively.
