Realistic Basics Creating Moving 2D Graphics: Layers and Keyframes
GCC Academy
Hello everyone, this is instructor Choi Ji-won
This session will cover creating moving 2D graphics
layers, and keyframes
Today's learning content is first, through a practice of creating vector graphics
using shape layers
we will understand layers in After Effects
Second, by applying animation
using keyframes
we will learn about acceleration and deceleration
using keyframes and the graph editor
Creating Vector Graphics Using Shape Layers
Yes, everyone, the timeline is the most important this time
The timeline panel
The last time we learned about interfaces
it was one of many
There was the composition panel, the project panel
the panel where effects are displayed
and even the timeline panel
Why is the timeline panel important among all these panels?
Because it is where the actual work is done
First, the timeline is where media files
are managed in layers
The concept of layers is also very important
and many tasks are done by arranging each of these layers
in the timeline and working with them
Also, this timeline is where the actual work is done
by setting the playback time of the layer
or creating keyframes
This time is very important
No matter what effect you put in
the time setting is important
You can control the speed
such as when it starts and ends
and tell various motion stories
so the concept of time is important
So, it's the timeline
What does this timeline have?
It has so many functions
I think it would be good to go over them one by one
First, I've enlarged the timeline
and the current time is set like this on the upper left
You can see the current time with this time indicator
If you hold down Ctrl and click on this
you can change this display style
to this timecode frame format
Right next to it is a search box
This is a quick find
If you press Ctrl+F to activate it
you can search for the layer's name or property
Next to it is this composition chart
Next to it is this who shows the composition
as a small flow chart
I think it would be good to click on them one by one
Next to it is the fourth Hide from Timeline panel
Smooth movement of the video
Show Layer's Motion Blur, Graph Editor
Next to it is the time navigator and the work area
There are so many functions just above
First of all, the current time is important to us
Another important thing is the time navigator
Time is the most important
The reason why this work area is important is
because we can drag and set
this work area
If the work area is narrower than I intended
or there are too many, the video may be cut off when extracted
or the video may be extracted too much
So it is important always to check that
this work area is set correctly
Another important thing is the Graph Editor
Graph Editor is important because it is about time
and this can finely adjust the speed
That is why it is important
The things to remember on the top line are Current Time, Graph Editor
Time Navigator, and Work Area
Then, if you look at
the things I marked with arrows below
there are many functions, but you will not use them all right away
so don't hate them too much
If you look on the left, you will see Show/Hide
This is shaped like an eye
If you click on this, the eye will turn off
It means you don't want to see this layer
Then, if you turn it on again, you will see an eye shape like this
which means you will see it
Next to it, Audio On/Off
also determines whether you want to listen to the audio of this layer or not
When you work on a lot of layers, it can get confusing
So, if you turn off the unnecessary ones for a moment, what will it sound like?
If you turn them on, what will it sound like?
You will need both of these a lot when checking
Next, there is Solo
This Solo means that only the selected layer will be displayed on the screen
and the rest will be hidden
Next, there is the lock, which is shaped like a key lock
Since there are so many layers
this layer is important and will never be changed
If you think you won't edit this layer
if you activate it, it will not be edited
That's how it is
The four in front of this are for viewing and locking
It indicates things like whether we'll see or listen or not
It indicate those
I think you can understand it like that
Next to it, there is also a tag
It has this tag shape, and the reason for this
is to indicate a label
There are names of layers like this
but you can't find them all by name, so when you have a lot of layers
you can label these layers with the same color
to indicate that they are similar
and can be grouped
This will reduce confusion when you work
That's why there are labels
Next, there is the name of the layer
You should name this layer well
Because it will be confusing later
So, we looked at the layer name
It is written in English a little complicatedly
but the Shy function
is a function that enables or disables hiding the layer
The second is the Collapse transformation
This maintains the 3D nature
of the composition layer, including the 3D layer
or maintains the rasterization
in the case of the vector layer
It's hard, but you don't have to remember it for now
Next, Quality and sampling
adjust the preview quality
Next, Effect, shows or hides the effect
When I applied the effect
What happened when I didn't apply it?
If you want to see it, apply this
You will use this a lot
Next is Frame blending
which is used to set the frame mix, which is often used
Next is Motion blur
What is Motion blur?
It is used to activate or deactivate the blur function
Next is Adjustment Layer
This is used when applying effects, and it is used a lot
There is one layer among the layers and when you want to
apply a new effect to the lower layer
you use this layer
Next is the 3D Layer, which, when activated
converts the layer to 3D
We will use that later
I think you can understand it like that
CTI, this is important
CTI is Current Time Indicator
It tells you the time position of the part displayed on the screen
Where it is standing is the screen I am looking at in the composition
I think you can understand it like that
At first, you don't use all of these functions
Usually, if you know the current time, CTI
and layer
you will not have any difficulties when practicing, so don't worry
Another important concept to memorize today is layers
Layers are so important
They are the most basic
Layers are an important concept
used in After Effects
When you arrange these layers
graphic spaces are created
Through arrangement
you can separate the background and objects
to create
individual and detailed work
Layers are what make everything up of
and because layers are classified
you can create various graphics
Okay, move on
There are many layers
but the most representative is Shape Layer
Shape Layer is a shape
a layer that creates various shapes
The second is the text layer
Text is text
There is a layer where you can write text
Then, there is Solid Layer
This Solid Layer is a cross-section
A cross-section, a surface
It is usually used when you want to remove the alpha value
from the background
What was it that I mentioned earlier?
There is also an Adjustment Layer
You can understand it like that
The next important concept is Keyframe concept
Keyframe concept is
an essential element in creating animation
Keyframes and layers are important
If you enter the desired value in the measurement time
you can use the stopwatch to create
the desired keyframe
It is related to time
If there are at least two keyframes, movement is created
You will understand this right away when you practice
This is because movement is created
This keyframe concept will be used often
so please familiarize yourself with it and practice
We will practice layers and keyframes
Practical Exercise: Layers and Keyframes
First, let's take a look at the compositions
The compositions are Maze Game Complete, Basketball Bouncing Complete
Character Creation Practice, Maze Game Keyframe Practice
Basketball Bouncing, and Graph Editor Practice
It's like this
I've created several compositions
so I'll put the indicator on Maze Game Complete
and press the space bar
This cloud character is going to the four-leaf clover
I will video him solving the maze and going to
the four-leaf clover
I made this once for keyframe practice
and will make a video like this
Then, there's the third character creation layer practice, right?
Click on it
Then, there's nothing
There's nothing
We have to make everything
But here
we're going to make only the four-leaf clover character
We're going to make only the four-leaf clover character
We're going to use the shape layer
If you go in the toolbar
you'll see the Rectangle Tool
If you click on this for a long time
you can see what shape layers you can create next to it
There are squares, rounded squares, ovals, stars
things like these
We're going to make the most basic square first
Think of this as a drawing paper
click and drag like this
Did you drag it?
You're going to drag it
Strange? When I pulled it earlier
it came out as a rectangle
but this time, it came out as a square
How do I do this? Press Shift
I'll do Ctrl+Z and do it again
If you hold down Shift and drag
it will appear square
I'll make it a square
I made it big so you can see it bigger
Since we're practicing, you can make it bigger
The red here isn't a four-leaf clover
Let's change the color
Here, there's Fill and Stroke
They're fill and stroke
and you can use them
First, let's press Fill
If you press it, you'll see options
like "No fill," "Fill,"
and "Add a little effect"
I will say, "I'm going to paint this,"
you can also adjust the Opacity here
If you put the cursor over it, an arrow will appear like this
If you move it to the left, it will be transparent
If you move it to the right
it will be opaque
First, I'm going to paint with a solid color
I've selected the option OK
Then, for the color
click on the square next to Fill
A color will appear like this when you click on the square
Here, I will make a green
a color close to green
You can intuitively create
the color you want
I thought this color was appropriate
so I set the number to 4FD9EF
I clicked OK
Then, we've created a light green square
Since I've painted here, we need to look at the Stroke, right?
If you click on the Stroke
there are four options
There will and won't be stroke
I'll apply an effect to the stroke
I'm going to use a solid color
You can adjust this Opacity as well
but to make it visible
I'll just leave it at 100 and click OK
Click OK
Likewise, clicking on the surface next to the Stroke
changes the Stroke's color
You can change the color
But in my case, I'll just leave it as FFFFFF
I'll just leave it as white
Click OK
If you look next to it, there is a Stroke width
If you hover over this
an arrow will appear like this
The wider you make it, the wider it becomes
the smaller you make it, the less it disappears
I'll make it 13 so that
you can see it well
Yes, let's make it 15
Make it 15
Press V
If you press somewhere else
a square will be created like this
Then, you might be thinking
How can I make this square point
in the direction of the clover?
Let's change it
This time, instead of the Composition panel
we'll look at the Timeline panel
I'll raise it to show you
the Timeline panel better
When I raise it, if you want to see the panel bigger
or smaller, you can click and drag
between the panels like I did
Likewise, you can adjust it
like this on the side
You can adjust it here, too
I think that's enough
We're going to work on this Shape Layer
in the third composition
So you should always select the layer you will work on
That's the only way to apply the effect
If you look next to the content, there's Add
What are you going to add?
Let's press the arrow
There are various effects
Let's select one of the effects
and use it
Let's press the one
called Pucker & Bloat
It's under Offset Paths here
If you press this
What happened?
There's distortion
When there's distortion
there's content called Pucker & Bloat below
You can open this
If you open it, it says Amount
This means how much distortion
you're going to do
How much?
If unsure
you can always adjust it
by placing the cursor over this number
Let's adjust it
The more you go to the minus, the more concave it becomes
the more you go to the plus, the more blocked it becomes
It's almost like a four-leaf clover
If you stop, it's about 75
It's about 75
You can make it like this
If you've made it like this
let's make a stem
Select the same shape layer
and make it with the pen tool
We'll make it with the pen tool
If you drag the pen tool on the toolbar
there are a lot of effects
but for now, we'll use the pen tool
I will draw it here
You have to follow it carefully
Click once
hen drag while holding the click
and then click once more to make a curve
Don't panic
just click on the curve like this
But I didn't want to make this shape
The same Pucker & Bloat Amount amount
as before was applied here
In this case, you have to drag this newly created shape
all the way down to the Pucker
and release it to solve the problem
A blue line will appear
If you drop it here
the effect won't be applied
This is because everything is based on the layer above
However, since this fill has been formed
I'll remove this
Go to Fil
Remove it
Done
Here, we need to adjust the position
of Shape 1 a little bit
To do that, go to Transform
Our position is slightly different on the right and left
so push it like this
and put it inside
If it matches like this, it should be about right
It should be about right
You've made it right
Now
since we made it with the pen
and rectangle drawing tools
press V to change it to select
merge it into one
and drag it like this
and go to Add with it selected
What should I do?
Press Merge Paths
Oh, what happens?
It becomes one
If the color disappears when it becomes one
move Merge Path to the top to solve it
Yes, you can make it like this
Yes, like this
I'm going to rotate the content itself a little like this
Go to Transform
click Rotation, and drag it
If you do it like this
it's a bit burdensome
so I'll reduce it
Do it like this
When we move, there are two things
There are two Scales
and two Positions
If you look here, there's a shape
hanging like a keychain
This means that it's going to move at the same rate
If you want to move them separately
you can release them
Click to release them
Okay?
If you've come this far
we can create something
with shape layers
We can create graphics
Among shape layers
we created it with the rectangle tool and the pen tool
You can understand it like this
You've all entered the mirror game?
Let's retake a look
How do we give this movement?
We'll provide it using keyframes
If you look at it, it only moves in the X-axis, Y-axis
horizontal, and vertical directions
Let's create an animation of it
moving and finding its way using keyframes
This is the finished version
So we have 1, 2, 3, 4, 5
If you go to the fourth
If you click on the fourth composition
there is this guy without any animation
The four-leaf clover will stay still
so that we will leave it
The cloud will move
so I made a mirror for now
I made a medium orange solid color, and the background, too
You just need to move the cloud
Shall we open the cloud?
The cloud contains various traces
and contents that we made
We will only use the transformation below this
Yes, it is very easy
We will only use this
If you click on the cloud transformation
and the position and position values are activated
This diamond is a keyframe that marks the time
and I set it to -181.4 and 132.1
I marked that position value
But we can't understand the distance
with numbers like this
So, we will not do it with numbers
I will move it by 1 second
If you drag this indicator
it will move exactly every 1 or 2 second
After moving it around 2 seconds
I will move this
I will move it to here in the composition
Move it here and let go
The moment you let go, a diamond appears in the timeline panel
This means that I'm going to specify this time and distance here
I will move the indicator to the beginning
and press the space bar
It came until here
I'll do it again
This time, I'll put the indicator at around 4 seconds No, it's a little short
so it's about 3 seconds
and I'll lower this
I'll lower it diagonally
I'll look at it again
It went and came down
Yes, it came down
Do you get it?
One more time
I have to go farther down that road
so I'll stop the indicator at around 5 seconds and go
I'll go all the way
I'll go all the way here
I have to go down again,
so move the indicator slightly and go all the way
Move the indicator again and go all the way
Move the indicator, and if it seems a little far
I've come to 11 seconds now
Let's go ahead and move it to the end
and then do a mid-check
You can move this guy's position value in the composition panel
without having to input a numeric value
In the timeline panel, position the time value
and move the distance position in the composition
Move it like this
Then go further
and this time, let's go a little longer
Go all the way to the four-leaf clover
I finished in 18 seconds
Let's take a look
Move it in front of the indicator and press the space bar
We arrived
This is how you can do it
It finished earlier
than the time zone I created
If you finish early and want to finish here
you can move this work area
I'll do that later
You can move this work area like this
You can only move the work area up to 18
and extract this much
Yes, do you understand?
We marked a point like this
and changed the position value in the composition
We did that
but now you can move it right here
or if you put the cursor over our numeric value like this
the numeric value will change
You can use that to create it
Enoughly
Then, there is one bad thing
What is it?
Can't we make this speed a little more natural?
This question arises
So we will practice the speed a little more
This time, let's select the second composition
Basketball Bouncing Complete
Let's set the indicator to 0, zero point
and play it
Play it with Backspace
How does the basketball go?
The basketball bounces and bounces
There is some kind of deceleration and acceleration
Let's practice how to make
this deceleration and acceleration for the basketball
We will use Graph Editor
You can adjust the speed quite precisely
So, let's use this function
This is another completed composition example
to practice the fifth Basketball Bouncing Graph Editor
Activate the composition
There is nothing
We will fill it in
How to do it is in the Project panel
There is a basketball PNG file
so you need to drag it
and change the scale to change it
If you set a keyframe
to around 860 in frame 15
it will fall vertically
It will fall
It falls
If you press Ctrl+C at the point of 860
you can copy and paste it at regular intervals
Copy and paste
I made
3, 4, 5, 6, 7, 8
9 diamonds
Right now, nothing has changed
It doesn't
Now, I'm going to make a change
How to do it? Graph Editor
Click Graph Editor
f you click Graph Editor
a straight line will appear, and the graph will appear linearly
but to make it curved and adjust it
select the entire thing
and then select Easy Ease, and a point will appear
A point will appear
and this Easy Ease can also be used with the F9 shortcut key
Click somewhere else
Did you see the points that appeared earlier?
We're going to adjust them
and let's make a curve
Please drag to create a curve
and then lower the curve from the midpoint here
Lower it a lot
Please create a curve that gradually goes up
If you make it like this
Shall we take a look?
Press spacebar, and ball bounces
The speed changes like this
Then, we can't make it in a place like this
So, let's take a look at our X-axis
I will drag the X Position to the left
with the indicator in front
Drag it all the way so that it's almost invisible
Let's do that
and then, with the indicator at the very end
drag the X Position
Should I make it go all the way out?
I'm going to make it almost out
I did it around 194.3
Let's see
Put the indicator in front
Put it
Ball bounces
It goes over
Let's retake a look
Give it a bounce like this
give this guy X Position the same Graph Editor
make two selections
and give it Easy Ease
Then, it'll be a little more natural
Bounce bounce bounce
Please move it yourself
to see how it can be more natural
How can I make it more natural?
Should we do like this?
Yes, please modify this bounce
to be more natural
Finally, close the graph editor window
and activate Motion Blur next to it
If you activate it, press the space bar again
and you will see a slight motion blur
This way, we have adjusted the speed in detail
including acceleration and deceleration
I think we have covered
a lot of very basic and important concepts today
We have learned that if you use keyframes and the graph editor well
you can adjust the speed
and create animations using that speed
We learned these
In this session, we created graphics
using shape layers
and applied keyframe animations
It was a time to familiarize yourself
with the various layers used in After Effects
and learn about acceleration and deceleration
using keyframes and the graph editor
It would be good to think of it
as creating a layer-like drawing on a piece of paper
and drawing on it to draw a moving picture
Then, let's wrap up
by summarizing what we learned in this session
Thank you
