- [Instructor] All right, checking,
back to our folder, transform tab.
Okay let's see how we did,
right here I want to go turn off the splines,
and turn on the mat overlay,
I'm on frame 24, 23, and 22.
Okay, well sometimes you got to do it ones, okay,
let's say we'd like to fix frame 23,
mat off, wire frames on, select folder, transform tab,
and I'm going to use the nudge keys on the keyboard,
remember the ten keypad can nudge, so nudge.
To nudge you got to turn on the on-screen control jack,
when I click on it, you see that white dot appeared,
the nudge does not respond
until you have that white dot lit up,
and that's why it's not been working for you, ha.
Okay so now I can give it the old nudge,
and get that guy in there, and the shoe,
let's say the shoe looks good.
I'm not going to worry about that, all right.
So the splines off, mat on,
and let's say we like that, okay,
we don't but let's say we do, okay.
Now let's roto backwards to the beginning of the shot.
So my first key frame was here on 11,
so I'm going to go back to
let's say frame eight.
I picked eight because
I'm starting to get some new action in the toe,
so I want to lock it between eight and eleven.
All right select folder, transform tab,
grab my on-screen transform jack, move it,
rotate it, let's push in a little bit here.
Maybe just a little keyboard nudge,
all right, if I super tune my rotation up here
with the thumb wheel in the tenth of a degree,
you can get some really, really accurate rotations.
Okay so let's get this shoe rotated,
all right, so let's say we like that.
Okay, eight and eleven, eight and eleven,
now let's check for in-betweens,
splines off, mat overlay on,
nine, ten, eleven, hmm, not bad.
This would be our worst frame,
if we wanted to fix it we would do nine, okay?
All right, mat overlay off, screen overlay on.
And let's go back and set another key frame
at, ooh, six, six is a big one, look at that, hmm.
All right, so, we'll grab this,
bring it up here, making sure, you know,
get folder, transform, right, okay.
Give us a rotate please,
and since remember my control jack now
or the little white dot in the center
it lit up so I can nudge and nudge, nudge, okay.
And then we'll go to the right shoe, grab him,
give him a little rotation,
now he has got a lot of motion blur issues, okay,
so we're going to have to do a little point twiddling.
So I got to switch to the roto tab,
so that I can move these guys around,
I'm going to grab them,
get my on-screen transformation jack control points.
All right, okay, well let's pretend
that that looks good.
All right, back to the folder in the transform tab.
So we're right here between six and eight,
how does seven look?
Let's turn off our splines and on our mat overlay.
Eh, we're getting a little bit of
stuff going on here that we don't want.
But we'll just move along anyway,
back to our key frame six.
All right let's jump to the very first frame,
okay and just to button this thing up, again,
folder, transform tab, screen jack,
over, rotate, position, shoe.
What's going on with the shoe?
All right let's,
again it doesn't want to play for me
so we'll go to rotate
and do it that way,
it was trying to de-tent.
Also now I got to move these guys in
'cause of the motion blur, got to tuck this in, right?
So I select them, go to the roto tab
to get my on-screen control jack,
pull them in, and life is good, all right.
All right, okay.
So, again selecting our folder,
making sure we're on the transform jack,
that just lights up my key frames for me,
okay, that's all I'm doing there.
And let's play that.
All right, for inspection purposes we'll come in here,
zoom in, again, splines off,
mat overlay on, maybe I'm in a little too tight,
and let's single frame,
okay, wow, we're really off here, okay?
I need an in-between, huh, big, bigly.
All right, so maybe I want the worst one,
maybe it's this one, okay.
Mat overlay off, on-screen overlays on,
folder, transform tab.
Give us a rotate, would you,
and we're going to need to do a little nudging.
So I got my white point at the center of the on-screen jack,
I can do a little nudging here.
I'll go up here to the property panel
and do some tiny rotation.
Okay, see how fine tuning that is, ever so tiny.
Okay now got to go back and touch up my nudging, don't I?
So make sure my jack is lit up in the middle
nudge, nudge, nudge, nudge.
Okay well let's say we like that, okay?
How about our shoe, looks like mister shoe,
I could use the transform on the shoe
nah we'll go to the roto tab, select those control points,
and just move that down just a skosh.
All right, splines off, mat overlay on,
let's see how we did.
Okay frame one,
we're going to do motion blurring in just a moment.
(humming)
Okay looks like four needs a little love too.
There, just a little touch up,
and for the shoe, we're going to have to
go to the roto tab so that we get the
point transforms, pull that toe in a little bit.
Okay, so let's pretend that we did a good job
and that we like our rotoscoping very much.
All right, next
we're going to have to turn on the motion blur, okay?
So let's pick a frame, a lot of motion blur,
oh, see that big shoe thing going on here?
Okay go to the alpha channel, let's turn off our overlays,
the motion blur tab, turn on global motion blur,
and there we go, let the machine do all the work.
If you feel the need to increase the amount of motion blur,
you do not increase the motion blur number,
that's your quality number.
You go to shudder, see that, whoa,
ha ha, back to default,
If you had a lot of big motion blurs,
with a quality of one you might start seeing some
banding in your feathered edges.
So what we would do there
is increase the motion blur setting
to smooth that out, okay?
But we're not going to do any of that here.
All right, so let's see what we got here.
(humming)
Clump, clump, clump, clump, okay,
this will give you the general workflow
for rotoscoping moving characters in Nuke.
Of course, roto offers a variety of challenges
because of the infinite variation in images
and how they move.
But with patience and practice,
you can become a capable roto artist.
