welcome to Nuke 2:04 in class No. 1

I'm very excited to be back this term

and we'll be starting right off with

the new features in Nuke 6

this week we're gonna handle paint and rotoscoping

the new tools that they've added in Nuke 6

and the next week

we're gonna hit the very awesome camera tracker

and lens distortion tools in Nuke X

I'll be using Nuke X today

but it is I am using tools that are in Nuke 6

the paint rotor tools

um so whether you have using nuke or Nuke X

today's class will work great

and next week you will need Nuke X

um which I believe should be available for the VPN

um to do the lens distortion and camera tracking tools

so let's go ahead and get started

just look at the footage we have

so I have the same shot

but with two different color passes

and this is common in commercial

so what we have here is an interior pass

which is gonna be everything inside the windows

this is what the clients want the look to be

this is not common in features

where you usually get the high dynamic range images

but with commercials

they just do a tell us any transfer

and we lose all that wonderful

data that either the film or the red camera had

that whatever shot it had

so we have a pass for the interior

but now our windows are blown

out so then they also give us a pass for the windows

so we needed to replace the windows in this scene

with the windows in this scene

and this is the window pass is something

I would also consider something called a flat pass

which is just kind of a neutral grade

to get everything in to the

to the computer without it being too hot or too dark

I'm just kind of a neutral pass

so we're gonna use that and we'll tweak it to uh

you know darken these windows a bit and uh

make it a little bit

less obnoxious out the windows there

so to do that of course you need roto

so let's start with the roto before we

get into the paint

and um let's roto on the flat passes

a little easier to see

and doesn't matter which pass you choose of course

cause they're both identical in line up

it's literally just

the color changes

back and forth

we'll see that's just color changes

so just like in Nuke 5 if you hit the Peaky a

where a busy utilles come in

now the road of paint tool comes in

so you'll notice right away there's new

there's a new UI where there's controls here on

the left and at the top

depending on which tool you choose

and each choose

each tool rather has a little drop down box

you have different little things you can select

and we'll go

through all these today

pen tool here's your bezier tool

this is gonna be

whether you select either a bezier tool

a B spine tool

or you can now do an ellipse tool

which would just be a circle

or a rectangle tool

there you have your different brushes

so we have a brush and eraser

and then we have clone reveal

and here we have blur sharpen and smear

and here we have dodge and burn

which can also be really useful

especially when you're doing map painting work

and stuff like that so

a lot more functionality new can and one neat thing

real quick before we I won't do this too much

but just talk about paint real quick

one cool thing I've already drawn these rotor shapes

and they're in the same Myrtle paint node

but I can paint in them now

I can smear them out I can do everything so it's it's

it's neat because the vector based shape

and I'm painting over it

so if I was to select it now

and move it

you'll see that the smear

will stay where it is

and the shape will go and if I move the shape back in

you see now it's not getting smeared

if I move it back in

the shape will now get smeared again

so pretty neat that the

shapes are affected by the strokes

now let me just

make this a little bit bigger here

and let's take a look at the

the new interface over here on the right

so this is your new controls panel for the Roto tool

so your outputs similar to what it was before

you have your red

green and blue output

and you just can turn them on and off by checking red

green or blue

if you only wanted to affect one of those channels

and commonly you'll be clicking off everything

but the alpha channels cause you just wanna create Roto

for example

you have an output mask option

this is handy if you want the alpha channel

that's for example

in this image

if there was an alpha

channel here to keep piping through

and didn't wanna change that

you could simply output

click a new mask here

for example

there's a default channel now

roto paint underscore mask dot a

so now that I'll put that

and I can just click off my alpha

so I'm still gonna get the alpha channel that

any of my strokes or shapes are creating

but it's just not gonna be in the alpha

so that can come in very handy um

also if you just wanted to

I guess you can rename a channel here

but it's um

it's just kind of an additional function that

could easily be done up here as well

because you could just create a new channel here

so change under viewers

your points curves

and transform handle of color

so if we change this to

something else

red for example and we'll change the curves to

let's go with the green

so now we have those defaults and transforms

I'll just leave there

so I'll close this without saving preferences

when you close that saving your preferences

um it will only be active

these colors will only be active in your current

as long as nukes currently open

as soon as you reopen

it's going to change back in default

so that's good to know

if you don't want these things to be permanent

then you can just sit close and you won't have to

go and change them back

so you notice that

these changed already

and then if we look at our circle

it's already it's taken the changes to

but the rectangle it actually has the changes we did

inside our custom controls in here

because these will override your preferences

where shape 1 has no custom colors assigned yet

we have our different um our red and green curves

so that's how that works

and the next one is just color so

if we wanted to have a pink

or I guess it's go with yellow already yellow

when I have a yellow circle and we'll make it visible

you'll see now we have a yellow circle

so that's just color

that would work with with paint strokes as well

so the good thing is even after you've painted

you can change the color of that stroke later on

obviously that doesn't apply with strokes in our paint

strokes such as cloning

revealing smearing

things like that

next to that we have inverted or not inverted

then you see now the yellow goes everywhere

make that look bigger

so again that's just for the straight shapes

it wouldn't affect the strokes of course

so inverter uninverted

next you have

your transfer mode

so if we wanted to change it

currently it's always default to over

I could change the hard light

for example

and we'll get a different result there um

this is mostly gonna be where your bullying operations

are performed for rotor shapes

obviously you can create effects like this

um color burn

color dodge

things like that

that may be useful on occasion

but I think mostly for

the kind of stuff nukes known for uh

you're gonna be using this for bullying operations

let's go back to over

and I'm gonna create a new shape

just click on my

there's a tool

just draw a shape real quick

I wanna also

I'm no longer

for those of you that used Nuke 5 in the past

I'm no longer holding control and Alt to draw the shape

I'm not holding any keys

I'm just hitting the left mouse button

and drawing my shape

and closing the shape there

so now my shape is on top of everything else

it's done at the top

so it's on top of everything else

so if I wanted to actually be um

secluded from everything else and actually take

cut a hole in this circle for example

I would just change this operation mode to minus

and now it's gonna be there

if you look at the alpha channel

oh let me turn on the app channel of course

and after you'll see that this is the rotor ship

I would expect

when you looking at the RGB

of course for Roto

um it's gonna minus uh

in ways we don't want

because it's actually minusing the background

the foreground or the foreground plate as well

so if we shut these off

and just hit m to show our mat

you'll see that

we're subtracting that mat from the other map um

so that's really the most

often you'll use it for so it's

usually gonna be either over or it's gonna be minus

and you'll see there's a little different icon for one

minus is there

I'll zoom on that for you

so just a little

left corner there

okay so the next one is what frame

or how many frames

the shape is currently set to

now shapes automatically default to all

while strokes default to a frame

the frame number you drew them on

so if we click on this

actually I'm sorry you set this down here

so under shape uh

here we are single frame so lifetime

all frames and you'll see that on that stroke

I just changed

it now says all instead of the frame number

so we click on this one which currently says frame 11

change the shape itself

so we'll just go to the end frame

so we only have two key frames

and we have a pretty good track there

so right there we now have an alpha channel

and I'll click this off

I'll just affect the alpha channel

and make my shape visible again of course

so now we have enough shelf just that window

by now we need to remove the two crossbars

so I'll go ahead and do that as well

so I'll just add a new

busy shape

and this time I'm going to tell it to be

minus so shoulder

going to the shape menu or inside the common menu

and change my blending mode to minus

and do the same thing for the other crossbar

and make sure that's all set to minus

and check out the Alpha channel

and there we have it

so now we have the window tracked in

all the shapes done

and we can see that we except you know

not too bad friend very quick

so that's how that works

and then we can now use that to put in our color grade

so go ahead and add mix this

and there we have it

so let's go ahead and close our rotor tool

of course there need some edge work and stuff in here

but you can see

that now our new outdoor windows track in there

and we can really do the same the other two windows

but obviously I don't need to repeat those

I think you guys

either play back or you think it's pretty simple stuff

saying you guys will get that

but now that we have the Windows done

the other new thing about the paint

row tool is the Beastline ability

so never driving busiest

now you drop Beastline so

the yellow boy's head is a perfect example of a great

way to draw Beastline

so let me just

open that back up and let's

what's in your property's panel

there we go

okay so now we're back up in the properties panel

so all these menus

if you just hold down

they the window will open

or if you right click

so just hold down

and then the Beastline tools like that

close the shape

so the beastlines are controlled by these tangents

and they're great for organic shapes

like a human head and the human body in general

so just like in Nuke 5

you just hold down control the feather

and to adjust the tension of the Beastline

you hold down command and shift on a Mac

control and shift on Windows

and you can see you control the tension of the

Beastline itself

so that's how the B spawn works

and again it would

because it was created

oh it actually wasn't created in the dupe in the group

but I can drag it into the left

window group

and now it will track with the track I did before

and then whatever frame I drew it on

let's see what I draw it on

doesn't have a key so I drew on the frame 20

which is good so now I can just move it over

and now it should stay because of the tracks there

yet for the most part

um just that the windows

little bit for the waist of the tracks not perfect

but that way that's how that works and um

I really will go much and more to the bees fine

that's how it works

I don't really use bees finds that much um

but I prefer busiest

but it certainly works great and that's really useful

especially on people

so let's delete that shape

I wanna talk about one more thing before we get into uh

paint a little bit more

um so say this box um

for whatever reason

say it was moving like Jello or something

so it wasn't these four corners didn't stay put

um obviously in this case with what the track we have

we could just draw shape and do it

but I wanna do a little bit more than that

so what's that

a new tracker

and track each one of these box

corners of this box here

I'm gonna enable all four trackers too

Tracker 2

Tracker 3

and Tracker 4

and if you notice when you're doing squares

you're gonna do this kind of tracking

you wanna keep these in the same order

so 1 is the bottom left corner

4 is the top left corner 2 3 as they see there

so let's just go and track those should track fine

oh it's not connected there we go that'll work

okay so track pretty good all four corners

and now I'm gonna draw another shape

this I'm gonna click on the roof groups that we do

create a shape outside the left window group

and it doesn't matter what that shape looks like

all I need to do right now is create a

a shape with 4 corners

so obviously it doesn't look right at all

doesn't match at all

so all I need to do now though

because I have that set up is gonna be transformed

or actually I'm sorry

I don't need to do anything

just sit there like this and use my

tracker tab

just click on each one of these

and bring it to the right point

so bottom left corner tracker 1 and paint

paint the hands out on the frames that it's just

it's impossible to patch anything in

and anyone who does this work

I'd love to see it on the forms

it's a great

discussion and it's definitely challenging enough that

I think there would be a lot of good discussion with it

um but that's it for this week's class

next week we're gonna get into the meat of the lens

distortion tools and the new camera tracker

and enjoy the shot this week

I look forward to seeing any questions or comments or

anything you guys wanna show on the forms thank you
