As you said guys rotoscoping is separating an object an element or a subject if you like from its background.
And then you can change the background and give it any other background you did like this very practical
when you didn't shoot in front of a green screen.
If you want to follow along with me please open the project file.
Rotoscoping started the AP and in this project you have four videos here.
You are going to try to work or most of them.
The first and easiest one is the man walking in the desert here.
If you just the other guy walking in the desert and then you want to separate this guy from the background
which is the desert very dull.
I put him like walking in the rain or at the fire or whatever you like.
I landed on one that is pretty complicated.
Very nice is to separate the leaves from the blurred background and not as there is quite some work
here to do because the leaves on the background are almost human of course.
The technique I would show you would even allow you to do this one very easily.
Then you have the photographer here a video we have already used and it's very interesting to use the
Schwann because she has some hair here.
Delegate you know that is that you want to keep after all the Skopec So usually when you are at a scoping
you don't want to use the whole video shot like for example there is nothing here and here.
You don't want that for example.
So you can decide where to start your footage.
For example you can start the footage from here and put the important.
Then go to whatever you want to and for example over here and put the outpoint.
Now you have defined your footage defining your footage here is much better than creating a composition
was the whole footage start me inside the composition.
This is a much better way because you have limited your footage and you know exactly what you're working
on.
So now after working on the footage panel you can click and drag the footage to create a new composition
and you know here you have the composition exactly like your footage.
As close.
The footage palette to the being in after effects.
The best way is to use the Rotto brush tool.
If you click on it you have Rotto brush and a fine edge.
Two very powerful tools.
Let's start with the rotor approach which will allow us to select our subject or the foreground and
later on the refined edge will allow us to refine the edges as simple as this.
We start with a lot of brush but you're not as in the composition panel here.
There is nothing I can't use the brush use a lot of brush in the layer palette so to open the panel
of course you know you click and here you are you are in the last panel.
Now this is the Rotto brush tool.
When it is green it's used to do the selection.
If you press alt or option on the Mac it will become red and you have a negative sign.
Now it is used to de-select foreground or background to adjust the size.
You can press control of command on the Mac and go left or right to make it bigger or smaller.
For example I make it this size here.
You're not quite practical.
Now the first thing to do is to set your timeline indicated at the beginning of your footage in the
composition panel.
Of course you notice that moving in sync here with the their palette.
And then you start doing the selection.
What do you want to do.
Is the best selection possible for now.
So I click and drag.
You are trying to select everything.
You don't have to be very meticulous.
Don't go too much on the borders.
No something like this will be OK.
Fine.
I love this work.
So usually I go very nicely.
One by Byron and I love the result.
Now you have done your first selection and you're not this you have a purple line all around the purple
line.
Well defined the foreground or your subject whatever is inside the glows purple line it is your foreground
and whatever is outside it is your background.
You can click on your compositional panel already and see the results.
You notice that the background does appear and what I've it was that within the purple line it's your
finger but you're not this we need to you know adjusted a bit over here.
Let's go back here and the way I like working.
First of all I like to look at the big elements for example.
We missed you know a big part of the address here.
So I'm going to click and start adding.
OK.
Notice how the line has moved and I'm going to do another one just over here.
Better yet is to press alt point whatever you want to select and roll the mouse button.
So you know exactly what you want to select.
So I press control here to make the brush a bit smaller.
Come over here and select this piece.
I'm happy with it.
It's very nice that you are very meticulous.
If you're past the spacebar move it will show you the results so you can come and you know see exactly
what has been removed and was staying here.
Here you are.
Very nice.
Now press over here and we know that you want to take the hair later on we will refine it but it's ok.
I don't like it very much.
I'm going to remove it.
You see I press alt or option on the Mac now and the minus I removed that will work is that the fine
tool to get this word right.
Good.
You want now to use the zoom in that's on or capture the Mac and photos slash video.
Let's go to the face over here.
I press alt zoom me in and simply try to take as much as I can.
Now I like to be meticulous.
I like to be very precise and it would save you a lot of problems.
And also your work will look much better and much nicer you know not like a beginner.
Over here I need to adjust.
I would roll the mouse press art to make it negative and then remove this bag on from here.
OK.
And another time up this space bar and goes down.
Yes.
And remove this background from here.
It's working very fine.
I want to adjust this one even more.
OK.
Here you are as good down and Helier fine and maybe maybe you would want to remove this duct.
It's working a bit too much.
OK.
This is being very aggressive.
Let's press art and forward slash to see.
Let's go to our composition and not this well.
It's OK.
It's not bad maybe here we need to look at it.
And the camera does take any piece we don't want.
I press I'll zoom in and here I want to remove this piece just over here.
Here you are again.
So you did the first selection do you just started.
And from this selection you're going to start refining the edges and the rotoscoping the whole two seconds
or three seconds that you have in the next lecture you start using the define edge tool to work on the
hair.
Thank you.
I'll see you in the next lecture.
