1
00:00:02,200 --> 00:00:05,170
[Autogenerated] in this clip, we're going to be looking at the remove note.
2
00:00:05,710 --> 00:00:06,690
Remove channels.
3
00:00:06,690 --> 00:00:11,890
Node allows us to very quickly get rid of other channels
4
00:00:12,090 --> 00:00:14,750
that we do not need for a particular task.
5
00:00:15,440 --> 00:00:19,760
This image has a lot of image layers.
6
00:00:20,130 --> 00:00:28,510
We have ale, multi diffuse body direct spec U V s.
7
00:00:28,590 --> 00:00:31,000
I mean, we have lots and lots of different layers,
8
00:00:31,000 --> 00:00:34,710
but we may not need those, so let's get rid of everything.
9
00:00:35,530 --> 00:00:42,230
Let's select remove and its default will remove all channels so you
10
00:00:42,230 --> 00:00:45,600
can see all channels are now empty for go back.
11
00:00:45,840 --> 00:00:47,430
You can see that on Lee.
12
00:00:47,430 --> 00:00:50,150
The default three are there now.
13
00:00:51,640 --> 00:00:55,100
So what we're gonna do is we're going to remove not but
14
00:00:55,110 --> 00:00:58,730
all but will remove just the oil multi.
15
00:00:59,050 --> 00:01:03,550
So you can see now that is no longer there and will remove
16
00:01:03,670 --> 00:01:08,900
body diffuse and you ve depth and multi Matt.
17
00:01:10,100 --> 00:01:13,380
And you can see as I get rid of those different layers,
18
00:01:13,390 --> 00:01:15,810
they're gone from the primary list.
19
00:01:16,080 --> 00:01:20,250
They're still in the secondary list, but they're no longer here,
20
00:01:20,260 --> 00:01:22,470
and you cannot select them or see them.
21
00:01:23,540 --> 00:01:27,640
Now let's go back to default and switch our operation not from remove,
22
00:01:27,930 --> 00:01:30,900
but to keep What are we going to keep?
23
00:01:31,320 --> 00:01:33,720
We can keep all or weaken.
24
00:01:33,720 --> 00:01:37,200
Just keep the UV depth.
25
00:01:37,590 --> 00:01:40,780
So now everything is gone except UV depth,
26
00:01:40,970 --> 00:01:45,940
which weaken select, but it's not in the RGB.
27
00:01:46,620 --> 00:01:51,480
So if we want to, just keep the UV depth, but copy it to the RGB A.
28
00:01:51,740 --> 00:01:58,380
We could use a shuffle or a copy note to move those channels around.
29
00:01:58,820 --> 00:02:03,050
The removed node is a really great way to remove data
30
00:02:03,540 --> 00:02:08,110
quickly from our image layers so we can composite with
31
00:02:08,110 --> 00:02:10,500
better workflow and better efficiency.
32
00:02:12,480 --> 00:02:13,430
To recap,
33
00:02:13,440 --> 00:02:20,870
I want to talk about how channels are the foundation of all good compositing.
34
00:02:21,640 --> 00:02:25,200
The shuffle node lets you rearrange your channels.
35
00:02:25,600 --> 00:02:29,550
Shuffle copy adds another input.
36
00:02:30,510 --> 00:02:35,090
The copy node moves and copies channel sets.
37
00:02:36,010 --> 00:02:42,390
Add channels will create empty channel sets and remove channels.
38
00:02:42,680 --> 00:02:48,060
Lets you easily delete large amounts of channels for optimization ins.
39
00:02:48,740 --> 00:02:50,940
Don't be afraid of these powerful notes.
40
00:02:51,340 --> 00:02:56,090
These nodes will help you define your greatest composites.
41
00:02:56,580 --> 00:02:59,350
I'm Daniel Smith and thank you so much
