- [Instructor] So far we've watched several videos
that demonstrate various aspects of the Nuke user interface.
Here we'll pull it all together to see the overall workflow
for building the simple little shot
that we've been working with.
So, the first thing I need to do
is read in my jet and my background plate.
To do that I need a node that reads in an image.
So, we'll come up here to the Images tab,
pop that up and select the Read node.
The Read node contains a browser.
My VFX compositing course is located on my Desktop,
and there's my Nuke VFX Compositing course here
and we'll go to the Lesson 1 Media
and there's my jet, jet fighter.tif.
I click on that, the browser shows me a copy of the image,
now we're not using any clips
because that's a little more complicated,
so I just have a single still image here.
Okay, that's the image I want, so I'll click Open
and the Read node lands in the Node Graph.
I'm going to hook the Viewer up to it
so I can admire my jet
and up here, I want to open up the Alpha channel
but I don't seem to see my channels.
That's because I've squeezed my viewer so small,
that the menu has folded up.
There it is.
Okay now, we'll look at the Alpha channel,
go, "Uh huh, nice CG jet" and go back to RGB.
Okay next, I need to bring in my background.
Now the behavior of Nuke is,
that it's going to land the node you pick at the last location
that you have clicked in the Node Graph.
So, if I click over here, click
and I go to the Image tab and get a Read node,
select my jet background ocean,
say Open, it lands the last place I clicked.
Now you'll notice that Nuke
is calling these images 1K_Super_35.
In fact, if I hook the Viewer up to the background
you can see it says the same thing right there.
Here's where Nuke gets that, it's from the project settings.
So, I'm going to click in the Node Graph,
type S on the keyboard,
we'll scroll down to where the action is.
When you bring in an image, Nuke looks in this list
to see if it matches anything in the list
and it matches right here, the 1K_Super_35.
So, Nuke looked in this list, saw it matched,
and put that label up here.
That did not change the project settings.
You'll notice my Full Size Format is still 2K_Super_35.
I want to change my full size format to match my shot,
so I'm going to select 1K_Super_35
and now my Full Size Format is all good to go.
The 24 frames per second, which is Nuke's default,
will be fine but the frame range,
which is one to 100, that default will not work for me
'cause I want a 50 frame shot, so I'm going to type in 50.
Okay, timeline switched to 50 and we're ready to go.
Now I want to composite my lovely CGI jet over my background.
To do that, I need to do a Merge operation
with the Merge node.
I want to set the Merge node right here,
so I'll select the Read node for the jet fighter,
come up to the Merge tab and select a Merge node.
Now it hooks the A side in to the image I had selected
because it does A over B,
the way you read this is A over B, okay?
We'll hook the B side up to the background
and viola, I have a composite
because my viewer is looking at the Merge node.
We'll just tidy up a little bit here,
this is kind of clunky.
Okay next, I want to brighten up the background
a little bit, it's kind of dark.
So, I want to add a Grade node
between the Read node and the Merge node.
I'll click on the Read node to select it,
that way my Grade node will land right here,
come over to the Color tab and pick a Grade node
and there it is and Nuke inserts it for me very nicely.
Thank you very much.
I want it brighter,
so I'm going to gain up the background a little bit here.
And then the next thing I want to do
is add some animation to my jet.
So, we'll select the jet,
come to the Transform tab and click on a Transform node
and it inserts itself right in there for me.
Very nice, thank you very much.
What do I want to do?
Let me click on the viewer
and type H so we push in a little bit.
The animation that I want to do
will be for Translate, Rotate and Scale.
The first thing I do, this is always the first thing you do,
is make sure you play head is at the start of the shot.
Then we'll set a key frame for the Translate
and then selecting the Rotate,
a right mouse pop up, Set key,
click on Scale, right mouse pop up, Set key.
So, I've set a key frame on frame one
for the jet's current location,
so there's no Translate, no Rotate and no Scale.
Now that we've set the key frames, in the next video,
we'll see how to dial in the animation.
