1
00:00:00,256 --> 00:00:01,536
Hello there in Welsh
2
00:00:03,072 --> 00:00:07,168
In the next video we're going to start getting into denoising and retraining at college
3
00:00:07,424 --> 00:00:10,240
It started took a little bit more about exactly
4
00:00:11,520 --> 00:00:14,848
The first thing I want to cover is what exactly is the day
5
00:00:15,360 --> 00:00:16,128
Between
6
00:00:17,152 --> 00:00:18,688
Because you may have heard these terms
7
00:00:18,944 --> 00:00:19,456
Entity
8
00:00:20,480 --> 00:00:22,272
All the concept behind both of
9
00:00:22,528 --> 00:00:23,040
Is pretty
10
00:00:23,296 --> 00:00:26,112
It's random imperfections in your
11
00:00:27,904 --> 00:00:28,416
Between
12
00:00:28,672 --> 00:00:30,976
Is that rain comes from film star
13
00:00:31,488 --> 00:00:33,280
Annoys comes from digit
14
00:00:34,048 --> 00:00:36,096
Brain is generally thought to be more than that
15
00:00:36,352 --> 00:00:36,864
Pleasing
16
00:00:37,120 --> 00:00:39,680
Because that doesn't break up the image into
17
00:00:40,704 --> 00:00:41,728
Red green and blue
18
00:00:42,240 --> 00:00:43,008
It's sold
19
00:00:43,264 --> 00:00:43,776
Luminous
20
00:00:44,544 --> 00:00:45,312
You can see Anna Wright
21
00:00:46,080 --> 00:00:47,360
Noise on the other hand
22
00:00:47,616 --> 00:00:50,944
Has varying intensities of your range of powder
23
00:00:51,200 --> 00:00:51,968
The red
24
00:00:54,016 --> 00:00:55,808
It also doesn't feel quite as you're getting
25
00:00:56,064 --> 00:00:56,832
Which is another breeze
26
00:00:57,088 --> 00:00:57,856
It's not
27
00:00:58,624 --> 00:01:00,269
Regardless of if you have green or no

https://t.me/joinchat/ailxpXoW3JVjYzQ1
29
00:01:02,620 --> 00:01:02,464
Terms are interchangeable
30
00:01:02,720 --> 00:01:05,024
And we will be approaching them in the same way
31
00:01:05,536 --> 00:01:06,816
So as composite
32
00:01:07,072 --> 00:01:08,608
What do we need to keep in mind
33
00:01:08,864 --> 00:01:10,400
When looking at green Earth
34
00:01:10,912 --> 00:01:12,448
Are there really two major
35
00:01:13,216 --> 00:01:14,496
The first is that
36
00:01:14,752 --> 00:01:15,520
Any compound
37
00:01:15,776 --> 00:01:16,800
Element that were
38
00:01:17,312 --> 00:01:20,896
It needs to have green applied that matches our original
39
00:01:21,920 --> 00:01:23,968
And what do we mean by match grey
40
00:01:24,480 --> 00:01:26,016
Or looking for these five
41
00:01:27,296 --> 00:01:28,576
The first is pretty
42
00:01:30,112 --> 00:01:32,928
You want to make sure that the greater adding isn't 2 and 10
43
00:01:33,184 --> 00:01:33,952
Or Tucson
44
00:01:34,208 --> 00:01:36,000
I need the blind with the fridge
45
00:01:36,256 --> 00:01:38,304
And this is tied and closely
46
00:01:38,816 --> 00:01:39,584
Luminous
47
00:01:40,096 --> 00:01:42,144
What exactly does luminous Curve mean
48
00:01:42,656 --> 00:01:44,960
Well brain is not uniform
49
00:01:45,216 --> 00:01:45,984
Applied across
50
00:01:47,008 --> 00:01:47,776
Typically
51
00:01:48,032 --> 00:01:52,896
Your blacks and your dart points are going to have significantly more visible Green
52
00:01:53,408 --> 00:01:54,688
In your highlights
53
00:01:54,944 --> 00:01:59,808
Is because a couple reasons in digital cameras that means that less light is reaching a sensor
54
00:02:00,064 --> 00:02:02,368
And so more rainy day mistakes and up
55
00:02:02,880 --> 00:02:07,488
Ending a break areas plenty of data is getting there and typically not is noise
56
00:02:08,256 --> 00:02:09,024
Another reason is
57
00:02:09,280 --> 00:02:13,120
Humans are much better at seeing the differences in contrast
58
00:02:13,376 --> 00:02:15,936
In dark areas as opposed to very low
59
00:02:16,448 --> 00:02:16,960
Areas
60
00:02:17,472 --> 00:02:19,008
And some matching your luminous Curve
61
00:02:19,264 --> 00:02:22,848
Is very important looks like a brief look at the exam
62
00:02:24,128 --> 00:02:27,456
Is green uniformly applied across the whole image
63
00:02:27,712 --> 00:02:28,992
The luminous curry Bazaar
64
00:02:29,504 --> 00:02:34,368
You can tell it looks a very strange and now let's go to the properly applied luminous
65
00:02:34,880 --> 00:02:36,672
Not see everything a City match
66
00:02:37,696 --> 00:02:39,744
I'm using the exact same green
67
00:02:40,000 --> 00:02:40,768
Between these two
68
00:02:41,024 --> 00:02:44,608
Only difference is I've turned off are luminous curve in the wrong
69
00:02:45,888 --> 00:02:49,216
The next thing we're going to have to keep in mind is the size of a
70
00:02:49,984 --> 00:02:54,848
We need to make sure that were match in the individual that call them particles
71
00:02:55,104 --> 00:02:56,896
Between our elements and our
72
00:02:57,152 --> 00:02:57,920
She don't want to
73
00:02:58,176 --> 00:02:58,944
Too big or too
74
00:02:59,456 --> 00:03:00,224
That's pretty soft
75
00:03:01,504 --> 00:03:05,856
The next thing is that green can come in varying levels of sharpness or softness
76
00:03:06,112 --> 00:03:07,904
He asked me to make sure that matches
77
00:03:08,416 --> 00:03:08,928
And
78
00:03:09,184 --> 00:03:12,000
Define thing is matching the irregularity in the
79
00:03:12,512 --> 00:03:15,072
In other words matching the general pattern
80
00:03:15,328 --> 00:03:16,608
Of the grain structure
81
00:03:17,376 --> 00:03:22,496
In general this is as much of a problem with modern day digital cameras because
82
00:03:22,752 --> 00:03:23,520
The census have
83
00:03:23,776 --> 00:03:25,568
Pretty good there's not a lot of pattern
84
00:03:25,824 --> 00:03:27,616
The noise is pretty uniform
85
00:03:28,640 --> 00:03:30,432
So does the five keys to matching
86
00:03:30,688 --> 00:03:36,064
Over practically matching green with bees in the next video in nuke but I just wanted to briefly talk about
87
00:03:36,320 --> 00:03:36,832
I can't say
88
00:03:37,600 --> 00:03:39,904
Let's move onto the second way that Grey
89
00:03:41,696 --> 00:03:42,464
And that is
90
00:03:42,720 --> 00:03:44,512
Brian May need to be removed from RL
91
00:03:44,768 --> 00:03:45,536
1 of 2
92
00:03:46,304 --> 00:03:46,816
The first
93
00:03:47,072 --> 00:03:47,584
Is there
94
00:03:47,840 --> 00:03:49,120
The green under ellum
95
00:03:49,376 --> 00:03:51,680
Either isn't moving or doesn't matter fully
96
00:03:51,936 --> 00:03:54,496
So we have to remove the grain and then reapply
97
00:03:54,752 --> 00:03:55,264
Correct
98
00:03:56,032 --> 00:03:56,800
And the second
99
00:03:57,056 --> 00:03:58,592
Is that removing Green
100
00:03:58,848 --> 00:04:00,640
Can help some of the work that were doing
101
00:04:00,896 --> 00:04:03,712
Be much more precise especially when you're team
102
00:04:04,224 --> 00:04:06,016
Let's take a look at an example key
103
00:04:06,272 --> 00:04:08,832
One side is the ground and the other is
104
00:04:09,088 --> 00:04:13,440
So here we have the alpha of our key and as you can see on the right side
105
00:04:13,696 --> 00:04:19,839
Green is less than 40 we're getting a lot of chatting at the Edge and that's a very common when you work on
106
00:04:21,119 --> 00:04:27,263
Once you remove all the noise you can see on the left that's a very smooth key there might be a tiny
107
00:04:27,519 --> 00:04:30,591
Bit of chattering but it's much more settled on the ridge
108
00:04:33,407 --> 00:04:33,919
Whenever you're
109
00:04:35,711 --> 00:04:37,759
And that sums up what to keep in mind
110
00:04:38,015 --> 00:04:39,295
When you're looking at great
111
00:04:39,551 --> 00:04:40,319
In your footage
112
00:04:40,575 --> 00:04:42,367
As long as you're following this principle
113
00:04:42,623 --> 00:04:46,463
You'll be set a girl green is typically pretty black and white cider
114
00:04:47,999 --> 00:04:50,047
And was very important to keep in mind
115
00:04:50,303 --> 00:04:54,143
Is there just because you're using the exact same camera as another
116
00:04:54,399 --> 00:05:00,031
Does not mean that your green or be similar green varies greatly under different lighting conditions
117
00:05:00,287 --> 00:05:02,591
Depends how the camera setup is it daylight
118
00:05:02,847 --> 00:05:04,639
Are you Saturday night scene
119
00:05:04,895 --> 00:05:06,943
It really depends so each shot
120
00:05:07,199 --> 00:05:11,551
Should be approached as if it's a brand new grain structure because you will see diff
121
00:05:12,319 --> 00:05:15,135
What's go ahead and move on to the next video put these concepts
122
00:05:15,391 --> 00:05:16,159
Interact
123
00:05:16,415 --> 00:05:17,695
Thank you very much for listen
124
00:05:17,951 --> 00:05:18,975
And I'll catch you in the next
8947
