MB Tutorial Part 33 : Animating with Keyframes Video Lecture | A Complete Course: Motion Builder - Professional Skills

alright an assassin here what we're
going to do is take a look at doing some
keyframe animation on our actor face
which as you saw on the last lesson is
connected up to the character face now
we've got mr. Zack in the hot seat here
and he is now going to show you how we
would first go about bringing some audio
into our scene that's okay i looked at
that's all she's doing good knob viously
one of the important things is to be a
ability to go ahead and bring some audio
in Council and he's going to bring some
audio in and he doesn't know i'm about
to show him real quick is or tell him is
now we can't do a lot of scrubbing here
because we are really stressing our
audio if you will on the system right
i'm with recording audio and pumping it
back to the mixer back in and playing it
at the same time this computer maddox
blue yeah we've already done this a
couple of times and it's it's becoming a
little frustrating because too much
scrubbing will cause this to just die on
us right so zach is going to show you
how we could go about bringing audio
into the scene getting it set up so that
you can see it on the timeline and
everything and then how you can scrub
but it from that point is that just
going to make up some animation without
scrubbing the audio just so that we can
keep the system from locking up on it
exactly what I really want you guys to
see how we can do or guys n gals let me
be PC here we're going to go ahead and
show you how you can scrub through the
the sound so you can actually listen to
it you'll be able to listen to it in
like fast motion slow motion so you get
really get a feel for not really the
words that are being said but for the
kind of sounds that will be coming out
of your like the mouth of whoever
speaking and then you can beat you'll be
able to change the sliders here inside
of your actor face to make your
character actually seem to mouth those
words to make the same sounds that's
right so the first thing we need to do
is get some audio in here now on our
computer we have a motion builder audio
file you won't actually have these this
is not a standard file that comes inside
a MotionBuilder this is something we set
up as a favorite path so you guys
learned how to do that in the first
video
so I'm going to go ahead and drag the 3d
buzz wave into the scene and let's go
ahead and play it once and just listen
to it welcome to 3d buzz this is an
example of facial animation with
quedaras motionbuilder ok so there's
buzz coming at us actually in two
directions now so what I'm going to do
is show you how you can get this into
the time slider just so you can see the
waveform because that can really help
when you're actually trying to animate
the stuff by hand to see where like if
you hear a loud sound you'll be able to
actually see it much like you see it
right here like your zip or we may not
actually be on the audio settings pane
down there we may have it locked on the
actor faces pain well which we're going
to need exactly so being able to see it
up on the timelines a really good thing
like just looking at this we know it
says welcome to 3d buzz and that welcome
is stressed very loud when Buzz first
says it and so we can actually see the
waveform really pick up right here so we
know one what's being said and we know
what parts to emphasize as we animate so
let's go ahead and get this waveform
into our transport controls I'll go
ahead and open up my audio section here
in the navigator and I can just drag the
3d buzz wave into the timeline and you
can just barely make out that way for
them actually if I drag this down let's
expand our timeline just a little bit
then we can actually see the waveform
very faintly as white in the background
now a lot of you may know that dragon on
a timeline once you've got audio in
there and other 3d applications will
then let you hear that sound as you're
scrubbing back and forth exactly works a
little bit different inside of
MotionBuilder right now let me go ahead
and enable scrubbing none of what I'm
about to show you will work unless the
enable scrubbing checkbox is activated
and we'll go since I kind of adjusted my
timeline i'll just hit rewind so we snap
to the front of it this is where we get
into a very delicate position with
recording this vtm right right i will
show you guys how we can scrub and then
what I'm gonna do is just pretty much
make my character mouth the word welcome
and then we'll see how that's actually
done how we keyframe I'll just do it for
you I'll be like well come I have like
an honest 3d scrub over here that's
that's going to be creepy but either way
either way we do this the just simple
fact is we're not gonna be able to sit
here and keep scrubbing through this
over and over or this computer might
explode and take half the house with
so I love exaggerating okay so we'll go
ahead i'll try scrubbing once i'm going
to hold down the jakey and then with the
left mouse button i'm just going to drag
a little bit now before i do that here's
how this works this is like an analog
scrubber which some of you who might
have a sound background might be used to
and that it's kind of like a knob and
the further you turn it the faster your
scrub goes in either direction so as I
hold down J hold down the left mouse
button to start to scrub over a little
bit we get slow motion that's good and
the faster we go the faster it'll scrub
until buzz sound like a chipmunk right
now yeah buzz buzz is just stressed that
we don't want to lose this again because
we've already gone through several times
exactly so there's how you scrub you
guys now know it's holding on the jakey
using the left left mouse button and
again i do want to read i don't want to
say something to reiterate the fact
about it kind of locking up on it's not
necessarily MotionBuilder it's the fact
that MotionBuilder with us going through
and scrubbing this audio and with the
methods that we use for recording the
audio at the same time we're really
pushing this card pretty hard right now
absolutely and that's what seems to give
us a you know a little bit of a problem
if we take and stop recording audio
ourselves from an outside source and
then just go about you know scrubbing
it's fine all day long right I've
actually I've done this several times
now and had not a single problem with
MotionBuilder we only started having
problems when we actually tried to
record both microphones into the
computer and play a WAV file at the same
time and scrub through it and animate
and then then yeah that's not good so if
you prod at this point now that we've
seen how we can actually bring audio
into our scene and how we can enable it
for scrubbing let's focus on keyframe
animation that sounds good so I'll come
in here under actor face we sounded like
a couple of agents again right there
yeah anyway so uh I'm gonna go ahead and
slide my transport controls up just a
little bit to shrink them down so I can
take my navigator and blow it back up
just to get a few more listings here and
let's say I just want my character to
mouth out the word welcome welcome
come so there's a couple ways I can go
about this the first thing you're
probably going to want to do is place a
key on every one of your channels now it
would be really dull to have to sit here
and with all nine hundred billion
channels you might have sit here and
click the little cakey on each and every
one of these so if you just select the
first one and you hit the key button
over here well that's the only one that
keys that's okay or we could just go
through and ship select all those yeah
that's what I did last time and I just
kind as okay Zack was kinda often never
never I was like wow Jack's about to
show me something so I didn't know and
be cool it's great nobody knows it
because it's just not true we're not
gonna worry about be animating the left
bra that we only want to animate the
mouth so we'll just keep all of the
channels on the mouth ki them all at the
same time another keyed at the first
parade that's how I knew it work yeah
well they're okay so once again zach
tries to show off and crashes miserably
alright no problem no no you did not
come alright so let's go ahead and try
to mouth out the word welcome the first
thing I think these need to go down they
let going to need to happen is the mouth
is gonna have to open okay so let's go
ahead and drag our time slider up we can
actually see the waveform in the back so
if we could want to kind of use that as
a reference we can we don't have to
scrub through this we'll just kind of
pretend I'm thinking about welcome
instead of opening well yeah first thing
you're doing is actually pushing those
lips okay but working oh yeah but person
your lips while you're close you get
this kind of fish a thing nobody could
see me do that but anyway so it wants to
see you did that thank you okay so I'm
just gonna go ahead will open the mouth
just a little bit and maybe we'll take
the whistle and start to bring it up
okay and so that kind of starts to bring
the lips together just a little bit
nothing major cuz you know when you're
just talking normally you're not really
emphasizing any of your syllables very
very clear just kind of you just really
relax right welcome and if you watch
yourself in the mirror when you just say
welcome to somebody you bring your lips
together but it's nothing really crazy
and really since that's the amount of
animation we have that's what we're
going to use typically if this were like
a big project and I was trying to get
perfect example facial animation when I
be doing is sitting in front of a mirror
and creating my own blend shapes inside
of my that looked absolutely perfect but
i'm going to go ahead and complete this
animation with our generic channels let
me go ahead and key these out here and
then right about here we'll get to the
ESO for like well welcome so maybe i'll
open the mouth a little bit more will
slide back on this and let's go ahead
and bring the corners of the mouth out
just a little bit
and I let's go ahead and key everything
I just moved
well not not looking too bad now we need
some kind of an L sound now we don't
have any uh sort of a blend shape that
just changes the tongue right now we
have we had one set up over in the
character thing but we don't actually
have a channel established just for that
so we're gonna be doing is kind of
bringing our characters mouth pretty
well close they won't be able to see the
tongue anyway whoa see what else should
be right about here I'm doing my own
scrubbing that's going and we'll go
ahead and bring the mouth down a little
bit let's say right about there maybe
and I'll just key it's the only channel
that I moved so we got well tongue comes
up and downs but behind the teeth it
actually did come up i'm sure well
current let's say we need it kind of
sound so we got to kind of fake that a
little bit it will bring in mouth square
a little bit let's try this will go
ahead and place a key very close to
where we just place this one in fact
let's go ahead and bring my timeline
really close together those that are
wondering obviously if this was the real
deal what we would have done is set up a
bunch of custom phoneme user channels
right very very rarely are you going to
try to actually animate out a character
speaking a conversation of soliloquy
anything like that without having a
whole big long stack of facial
expressions of your mouth saying
different sounds and you know the best
thing you can do is really go to your
local store and pick up a little shaving
mirror or something and just have it by
your computer and watch yourself talk so
just kind of moving along let's see
we'll put a keyframe very close by with
blends into the mouth square kind of
make his jaw pop open a little quick for
the CUH sound
and I'll try kina see how this is
looking well I need to open up a little
more right there so i'll go ahead and
jump back to that keyframe and let's
just pull my mouth open just a little
bit i'm thinking and wilke that
well yeah not bad and we just kind of
need to really blend everything back
down to an um which is just bringing
your area bringing them out back close
so we'll go ahead and drag all these
back down and don't forget mouth square
that we set way back here and now with
all these selector we just go ahead and
hit the key button again and let sure
whoa um okay not bad we can play through
that if we want to welcome that's not
bad actually as we watch that play
across it really sounds like he's saying
welcome welcome and I don't to play that
too many times because who knows the
machine might explode again okay well
actually at this point is there anything
else act that you wanted to show is that
pretty much gonna cover just basic
keyframe animation that covers it right
there we got all the way through one
word and I know it's a small step but I
mean if we go on like we could just grab
our timeline and move it down and then
attack the next word is gonna become
very repetitive for this lesson and
people will get bored and send us
letters and we just don't want that
that's right so quick recap basically
what we did is in this lesson we showed
you how we'd go about bringing some
audio into our scene by simply dragging
and dropping the wave into the viewer
once that was established and we went in
there and we enabled inside the audio
settings pane we enabled the ability to
scrub the audio then we showed you that
we could simply grab okay we could grab
that audio and drag and drop it up into
our timeline and then once we did that
we could then use J after we had enabled
the scrubbing to be able to scrub
through the timeline so that we could
then hear the actual audio absolutely
and Zach talked about it being like an
analog scrubber where while holding the
j/ki down on the keyboard as you scrub
back and forth by dragging your mouse
left and right it'll go forwards
backwards and you can control the speed
which can be very handy while you go in
there and you're tweaking out all of
your key frames let's think the haughty
look nice and slowly can be very freaky
to to take buzz and make it sound like a
little chipmunk okay yeah he was doing
that all day long
so basically that's it that's going to
cover everything that we wanted to talk
about in this lesson right here so thank
you guys very much and just as a quick
reminder before we take off yes well
remember we are animating with the actor
face we're not using the character face
at all just in case there's any
confusion from the last lesson that's
right actor face is driving the
character face which in turn drives the
blinch I just want to keep throwing that
out there in case people are getting
confused sounds good all right thanks
everyone
