[Autogenerated] in this clip,

we're gonna go through the shuffle node and let's just take a look at

where we get our shuffle notes from And in fact,

all of the channel nodes there, over here in this icon A is like a stack,

and these represent layers or channels and you can see we get the shuffle

note right here and right below that is shuffle Copy.

Now, if you select this, we get a shuffle note.

Now, we have a default shuffle note over here, and I'm gonna open it up.

We can see it's interface now It's directly attached to our image of

thehuffingtonpost er and you can see our red channels coming in red,

going out to read and so forth.

But if I check off blue right here,

it's now taking the Blue Channel and reinterpreting it as red.

And then we get this funky inverted color scheme.

If I take the Blue Channel over here and I reassigned that

take the input of red and output it the blue.

We even further complicate the color scheme.

But Green is still in the same place Now we could take

green and we could reassign it down here,

or we could take green and just copy the green to every channel.

So now green coming in is going out as red,

green,

blue and let's just go ahead and check off Alfa to and that what

happens now as we create an essentially a black and white image

that represents on Lee the green pixels.

Now, if I do this same thing to the red,

you can see that it is slightly different

interpretation of a black and white image,

because now it's just the red pixels being interpreted as the black and white.

And we can also do the blue.

And you can see Blue has so much darker values,

especially in things that are green or or the blue helicopter itself.

So let's return this back to normal Red, green, blue and Alfa.

Now you'll notice that I cannot select the incoming Alfa Channel.

Let's take a look at that.

We can see that right here that completely PNG.

It does show that there is an Alfa Channel embedded in the image.

However, the input of the shuffle note is set toe rgb,

so it's not reading the Alfa, so let's click on the selector and select R G B A.

Now this is RGB A.

It now shows that I can select the A and Aiken Select.

It's incoming Alfa to go out as an Alfa.

Now let's take a look at that Alfa Channel.

I'm gonna hit a and we can see that the Alfa Channel is pure white.

We can use these internal options here to rearrange at Alfa Channel.

We can say Alfa Channel could be a copy of the blue,

a copy of the green copy of the red.

Or we could flush it with black or flush it with white.

It happens to already be white, so that's kind of redundant.

But that's what these do.

They basically override that central channel that it already has.

Now we can also take from other things up here,

Weaken, Say, Oh,

you know we're not gonna and bring in anything which seems silly.

We can also bring in just the Alfa and you can see

it puts the A in the first slot.

We can also bring in other layers.

Now these other layers are in this drop down because

they do not exist in this image.

If the layers existed they would then appear in this primary

drop down and then there's also new and new.

We will cover in another clip.

So I'm gonna go back to RGB A and what we can also do is we can

input from other sources so this in to weaken,

select Alfa and have this RGB so we can have rgb an Alfa

expressed in these to drop downs so I can put the Alfa over

here and copy it instead of selecting.

And over here now this becomes extremely useful when using embedded

layers because then those embedded layers which will cover in

another clip will allow us to select that.

Let's return our image back to RGB and we can see what we have here and

let's take a look in the next clip of shuffle copy.
