In this lesson, we're going to learn how to edit shapes in the Roto node,

and how to add more points to Bezier shapes that we've already created.

OK, so we're right here where we left off in our last lesson.

And I want to go ahead and show you how to edit this shape to fit

this jelly bean just a little more closely.

Now, you may be saying that's pretty close,

but sometimes you really want to get a shape that

matches that contour perfectly.

Especially when you start working with human figures,

and things that are really obviously wrong,

because it's something that is very widely recognized.

So we want to practice on a shape like this,

and then by the time your rotoscoping people at the end of this course,

you'll be a pro.

So what I'm going to do is just show you how to edit one of these handles.

So what I want to do is just make sure that I have my Select All tool selected,

just right there.

And then I'm going to click this handle right here.

Now, you can see that I have pulled these handles out and just,

unsuccessfully,

I cannot quite get that to go down into this curve

without messing up the curve on this side.

So one thing I can do is just by pulling that out a little bit there,

I can hold the Control key-- so I'm pushing the Control key right

now-- and now I'm going to grab this handle.

And you can see that now I have the ability to manipulate

that without using the other handle, and moving that other handle around.

So that's going to be really useful for us later on.

So I'm going to tilt this down a little bit just to make that

follow this curve here a little bit better.

Then we can come over here on our other side and do the same thing.

So I'm going to hold Control and pull that down.

So you can see that that really helps to give us

that contour that we're wanting, and really make that look a lot better.

Now, you still may be wanting a little bit of a prettier curve on the side.

So you can see how this comes to a sharp point,

and then starts to curve around down to the bottom.

So let's say that we didn't fix it in this way,

we didn't use the control-click method.

I'm going to undo that that I did earlier until-- I'm hitting Control

Z a few times-- until those handles pop back to that position where

they're directly across from each other.

And you can tell that this curve effects this curve over here.

So what I'm going to do is we'll just kind of flatten that back out.

And now I want to add another point right here in the

middle of this curve that's going to allow me to just pull

that point down into that area.

So sometimes you're not going to know that you need an extra point until later,

and you have to add it after your Roto shape has been closed.

So the way you do that is with this tool, right here, the Add Points.

Now, Add Points is just what this starts out with.

There's lots of other options in here, as well.

So let's choose Add Points,

and I'm just going to click it right there in the middle.

And you can see that it automatically gives me a Bezier point,

so I have handles on both sides instead of just a regular point.

So that's really helpful.

Now I don't want to add any more points, I want to move this now.

So I don't want to click it again with the Add Points tool selected.

I'm just going to go up there and choose my selection,

and we'll pull this point down now.

And maybe pull that handle out a little bit over here,

maybe a little bit on this side.

And now that Roto shape looks great.

It's just perfectly hugging the contour of that little jelly bean.

OK, so now let's take a look at our other jelly bean.

I'm going to switch over to Bezier 2.

And let's go back over here to frame 4 where we drew that.

You can notice that by that blue line on our timeline.

And one of the problems we had was kind of similar.

We had a point they didn't have any Bezier handles

because of the way we drew it.

I simply clicked the point at the end instead of clicking and dragging.

So we don't have any Bezier handles.

And we definitely need a little more of a pretty curve here.

So to achieve that,

you simply want to use your selection tools to select that point.

And then we'll come over here to the Add Points tool, which is the default.

But we have all these other tools inside of that.

And the one that we want to use to get Bezier handles is Smooth Points.

So Smooth Points is going to give us those handles.

So I'm just going to choose that, and then click that point.

Now, just by clicking it, it gives me the handles.

And if I try to start dragging them out,

you'll see that it's not really helping,

it's just making that curve a little more smooth.

But you can see that the curve has been smoothed out.

But if you don't want to continue just making that curve more and more smooth,

you want to actually get in here and edit,

you have to go back to that selection tool.

So don't forget to do that if you don't want to mess up your mask a bit.

So I can decrease that over here on the side,

maybe pull this one down a little bit.

And in the end,

we may actually need to go around to this point we have here at the bottom,

and pull that in a little bit better to give us a nicer curve there

that is closer to this edge of the jelly bean.

So that's looking pretty good.

I really like the way that that works,

and that's just a few of the tools that you're going to be

able to use to create those Roto scopes.

And I would definitely recommend in between lessons play around with

what happens with some of these different tools.

Maybe come in here.

What happens if you don't choose Smooth Points, you choose Cusp Points?

We can go ahead and do one of those now.

I'll just select that.

Now I'm on the Cusp Points tool.

And if I click that,

basically what happened was it took it back to what it looked like before.

So now we just have no Bezier handles on that point.

it It's been taken away, and now that point is more of just a harsh angle.

So really interesting the way that this tool works.

And eventually in this course,

we're going to get into keying these masks to move over time.

So then we'll be able to move that shape along with

this little bean as it rolls around,

and you would be able to have this shape follow along.

But for now, we're just drawing and editing.

Now,

what happens if you have to draw something a little

more complex than a jelly bean?

Say, maybe a human hand, for instance.

There's a specific way that you should rotoscope pieces like that,

images like that, that have multiple pieces that can move around.

A hand has lots of joints because of your fingers.

So the basics, though, are still the same.

So if you know how to rotoscope a jelly bean, you'll be able to do a hand.

And we're going to learn how to do that in our next lesson.
