All language subtitles for 05 - Wrinkle, Blemish, and Imperfections Removal - 2D Tracking and Roto for Her Face

hey guys in this module

we're gonna look at some different techniques

on how to remove wrinkles

blemishes and other types of imperfections

we're gonna be working towards trying to maintain

as much detail as possible in the surface of her skin

just to make sure we

end up with a photorealistic result

so when you're ready

let's get started

so in the previous module

I showed you guys how to isolate your grain

and explain to you why it is important

that we can isolate it

so we can maintain its quality

and apply it in the end

after we've done our other work on the image

and now I wanna show you another reason

why it can be really useful to isolate the grain

if we take a look here

at the grain as we did before

gain up the image here

gonna go to another frame

we can see that we have a lot of detail in here

actually almost we

we see her entire face just in the picture of the grain

so first I wanna

cook the grain together with our denoist image again

so we have the denoist image

or isolated grain

and we apply it on top of the denoist

so we end up with our raw plate image

it's exactly the same

and what is usually the case

is that you can see

that some of the imperfections we want to remove

are actually part of the grain image

as you can see some small ones here

and to show this even further

I'm gonna put a blur after the noise

and exaggerate this just a notch

so you get a better understanding

of what's going on here

so now I'm blurring the image

and essentially just applying the grain on top

and you can see here that we clearly have

some of these imperfections that we wanna get rid of

and they are part of the grain

so removing these

are not just as easy as blurring the grain plate

because we cannot do that

and we can also not apply

re grain inside of our original grain plate

that's not gonna work either

because it's not gonna match

you can spend a lot of time trying to match the grain

in the re grain to the plate grain

and you probably not gonna get amazing result anyway

because what we don't have in the regain

that we have in a grain plate

is the other types of detail we see here

and that type of detail

we do not want to get rid of

what we instead are gonna do is we gonna sheet it

and we gonna roll throughout

the imperfections we wanna replace

and we gonna offset them

to pull in a clean piece of grain skin

and put on top of it with a transformer mask basically

and we will use the tracking

that we lay down in the previous module

just to make sure this stick properly

let's start by making some rotos

and we gonna use the tracks

that we created in the previous module here

and we already have a stabilized image

Wanna begin with isolating the blemishes in the

bottom of the forehead

so I'm gonna select only the tracks

that are close to the area that I wanna treat

so we get the

the best tracking possible for this area

and I can see here

that it's probably gonna be best to keep the eyebrow

and probably the eyes as well

I'm just gonna disable the other tracks down here

because the area we gonna treat this just one up here

so just gonna

disable these and also make sure that we don't use them

for the overall transform here in the time

so we now have the eye tracks

and the eyebrow

and just gonna preview this and see

it's really stable or not

I'm gonna buffer this and pause for you

and we resume after

so in the beginning here

we didn't have enough values to keep our

vertical alignment

you see her head is tilting to the side here

so not enough information in our tree

select the trackers to

to work there

so I'm gonna

I'm gonna select some other track

and that we did here down at her mouth

just to align this in the beginning just

just for the simplicity of

of working in one axis like this

keeping everything in one direction

so we gonna enable

rotate here

and then I'm gonna buffer this for you

and we take another look

and we're back

and if I play this

you can clearly see that now

her face is keeping the vertical alignment

pretty well there

so let's just carry on to lay down some some rotos

some people like to put the tracking translate values

directly in the road to when they

when they do something here

to get the tracking information

but I like to stabilize the plate as much as possible

and then I put my viewer here

and then I just start working on my rotos

while watching the stabilized image

and then in the end

when we finished all the rotos

we gonna apply another tracker below the road

to set it to match move

and that way we get the tracking

transform information back on

and everything will stick as we want

so first let's start with isolating some of these

so let's make sure our reference frame

is always set to the frame

that we put our first road on

so ninety seven in this case

otherwise you're

there's gonna be an offset on your road on

and that will be a pain to fix

so since we wanna remove these blemishes here

we just gonna put a bigger roller shape here

and then one up here

but first let's apply one row to here

and try not to get into the areas

with contrasted details

or any area we don't want to remove stuff on

this is probably gonna be enough just to show example

we also we need to isolate this part

like that and actually let's look through our

the one we set up here yeah

it looks like these are the worst ones actually

and maybe we have some something down there as well

yeah I think we gonna put one rotor shape here also

let's go back to our tracker view

and let's do like a

just a rough shape here

you can always go back

and tweak these afterwards you know

but just lay down some simple ones now

and we can easily preview the results for this

so I wanna split this up in different roles

because they're gonna need different transform values

depending on where they are

like maybe some places

such as up here

we wanna bring grain from this side inward

but maybe in this one

we wanna bring grain upwards and down

so move it from here down here to cover

so that's why I wanna isolate them

so I'm gonna cut this out from this roller

just paste it inside this one

and I'm gonna do the same with the bottom one here

just cut it out

and create another photo paste it

and now wanna look at this so

now we're gonna work on top of the isolated grain here

so let's just clean this up a bit

this is just for preview

we don't need that

and let's move our rotor shapes

over to the left side here

we disable the blur

so down here we can easily preview what we're doing

I wanna select the top one to start with

and we're gonna apply

copy the tracker put

put it underneath the roto

and in the transform

we're gonna apply a match move

instead of our stabilizer

so now it's gonna apply the whole stabilizing operation

but inverse it

so we actually track the roto on top of her skin now

and then we do a transform masked

and if we take a look here on the grain plate

if we transform this

let's say 10 pixels to the right

can see that it moves up here

and also the imperfection we wanna get rid of

we essentially just squeeze it out

from the rotor that dries

and this is starting to look pretty clean now

and we even have the detail in the skin

that's baked into the grain

we still keep that

so this is some much better idea and way to work

than just trying to blur it away

so let's disable this

look at the end here

where we combined the grain

with the denoid so we get the plate

and if we enable our transform here

indeed see that

we shuffle some of this noise to the side

and the edge is looking a bit hard here

so we're gonna add a light blur

just blur this edge maybe a 10

sorry a 5 or a 10

I think a 10 is about right

and we still have some blemish here

but actually

if we look closely on the grain

that blemish does not come from the grain

it's baked inside of the rest of the plate

that does not have the grain

so this is the pass without the plate grain applied

and this is the one we will be working more on to

to make her skin smoother

and some other tweaks and beautifying effects

and we will look at that after we finish this

on the grain

but just so you know that

you cannot get rid of everything

just in the great grain pass

because everything is not located in the grain

so let's take a break here

and we will resume cleaning up the rest of the areas

in the next clip
