Hi, welcome to Animation For Anyone, my name is Alex.
2
Today's lesson is a bit of a crash course in animation.
3
We'll start with how animation works, and then I'll share with you the six ideas
4
that I think are the most important to understand when you first start animating. And after
5
that, I want to show you my thought process for how we can use multiple animation ideas at the same time.
6
Let's jump in.
7
I think the easiest way to understand how animation is working is by looking at a flipbook.
8
If you're anything like me, you might have made little animation flipbooks out of your exercise books at school.
9
You draw a picture, and then a slightly different picture, and you keep going until you flip through your pages and see your pictures move.
10
This is how pretty much all animation works.
11
Recreate still images and play them back quickly to create the illusion of motion.
12
If you've never tried it, maybe spend a few minutes now.
13
It's pretty fun.
14
Flipbooks are a good way to visualize animation, but they're a little bit hard to demonstrate the ideas i want to explore today
15
so instead i'm going to use a coin and capture the visuals digitally
16
that lets me play back the animation at a constant predictable
17
speed of 24 frames per second in future videos i'll show you how to do this
18
but for now we're really just looking at the ideas behind the animation
19
and how to plan out the movement so
20
if i want to animate this coin moving from one side
21
of the piece of paper to the other i take a picture of it move it a little
22
and then take another picture and then keep going until I get to the other side.
23
Now, when I play the images back, it feels as though the coin is moving across the screen.
24
Looking at it though, I think it feels a bit weird.
25
I think the most important question you can ask yourself while you're animating is how does this motion feel?
26
This is my guiding principle while I animate.
27
All of the fundamentals we talk about today and in future lessons really come back to this one question.
28
So if I ask myself, how does this motion feel?
29
I'd probably describe it as jumpy or jittery.
30
Let's look at why that might be happening.
31
Below the coin, I've illustrated the exact spacing of each of the frames.
32
You can see that it's not very even.
33
There are frames that are really close together and there are frames that are really far apart from each other.
34
And that's because I've not been very deliberate about how far I move the coin each time.
35
So if this motion feels jumpy or jittery now, I think we can make the motion feel a bit smoother
36
by making the spacing between the coins a little bit more even.
37
Now that I've evened up the spacing, you can see that the coin moves a little bit more consistently across the screen.
38
There's no more jumpiness.
39
At the moment, the coin moves across the screen in one second, or 24 pictures.
40
Let's see what happens if I move it across the screen in less time.
41
I think we can see two really clear things here.
42
The coin moves much faster, and the spacing between the coin is much larger than before.
43
Let's see what happens if we make the coin take longer to cross the screen.
44
Okay, I think that the results here are pretty clear as well.
45
The coin feels like it's moving more slowly, and the spacing between the coin is much closer than before.
46
So this is the first big idea in animation I wanted to show you.
47
Things feel fast when they're far apart, and slow when they're closer together.
48
So if I ask myself now, how does this motion feel, I'd say smooth or consistent, but maybe a little unnatural.
49
The coin starts moving suddenly and then stops moving suddenly.
50
So if we wanted to make a more natural feeling, the coin could start moving slowly, speed up in the middle, and then slow down at the end.
51
We start slow by having the coins closer together, and then gradually get further and further apart,
52
and then we slow the coin down by making the spacing closer and closer until we come to a stop.
53
I think that's starting to feel a bit more natural.
54
For this next step I'm going to loop the animation so
55
that the coin travels from the left of the screen to the right and then back again, using the exact same spacing.
56
For this next step I'm going to exaggerate the speeding up and slowing down a little.
57
You can see that the spacing's changed, so the parts that were close together before are even closer together now, and the parts that are far apart are even further apart.
58
Let's see what happens if we exaggerate it even more.
59
You can see now it feels a bit more lively or zippy.
60
We don't always have to start slow and finish slow either.
61
Here's an example of how changing the acceleration can entirely change the way the motion feels.
62
In this example, I have a coin that slowly speeds up, gets really fast, and then changes direction suddenly.
63
This gives us a kind of bouncy feeling.
64
One thing that I think is quite important to mention at this point is that these motions all feel quite different, but they have the exact same timing.
65
They all take 24 frames to get from one side of the screen to the other.
66
All of the difference in the way that they feel comes from the amount of space we put between the frames.
67
So this is the second big idea I wanted to show you.
68
If we want to make things slow down or speed up, we gradually get closer and closer together or further and further apart from each other.
69
This is called acceleration and deceleration.
70
Some people call it easing.
71
Or you can just call it speeding up and slowing down.
72
So far, all of our animation has been done using a coin, which doesn't change shape.
73
I'm going to start using a cutout piece of paper so that we can change the shape as we animate.
74
In this first example, I'm going to take the fastest frame of animation and stretch the frame out a little.
75
This changes the feeling of the animation.
76
I think it feels a little less rigid, maybe more zippy, more lively.
77
Let's try changing the shape again, but this time we'll squash it.
78
I think the best example to demonstrate squash would be our bouncy animation.
79
I'll start by stretching out the frame where we're moving the fastest and then squash it where we change direction.
80
This is going to make it feel a little bit more like a bouncing ball.
81
Squash and stretch is the third big idea I wanted to share with you.
82
It's great for adding a little bit of life to your animation and making it feel less rigid.
83
It also really helps the audience understand what the object is made of.
84
This coin doesn't squash or stretch as it bounces, so it feels quite hard, whereas a rubber ball might squash and stretch heaps, which is what makes it feel rubbery and stretchy.
85
So that's three big ideas covered, and I've got three more I want to show you.
86
The first is anticipation.
87
Anticipation is a really important part of animation, but it's something that's easy to forget about when you're first starting out.
88
Anticipation does two key things.
89
It builds up energy and it also gives the audience an indication that something's about to happen, which really helps with clarity.
90
When I think of anticipation, I think of a spring.
91
It builds up energy in one direction and then releases it all at once in the opposite direction.
92
You might like to think of someone jumping.
93
Before they jump up in the air, they often move down to build tension in their body this
94
downwards motion is the anticipation in this example i have a ball
95
that moves quite suddenly
96
and then slows down to make it feel more natural i
97
could add a little bit of squash to anticipate the movement this makes it feel like we're building up energy
98
and releasing it all at once the fifth idea i'd like
99
to talk about is overshoot overshoot is like a mirror image to anticipation.
100
Imagine you have a really big movement, go too far and then bounce back.
101
Overshoot helps add weight or springiness to your animation.
102
In this example I've added a double overshoot to the ball as it springs back into place.
103
You might have noticed that all of our motion so far has been along a straight line.
104
The last idea I'd like to talk about today is arcs.
105
Things in nature don't usually follow a perfectly straight line.
106
More often than not, natural movements follow some sort of arc.
107
Arcs tend to add flow to your motion.
108
In this example, I've taken our coin, and rather than moving it directly across the page, I've swung it down like a pendulum.
109
This gives it an entirely different feeling.
110
Okay, so those are the six big ideas I wanted to talk about today.
111
Let's have a bit of a recap.
112
Our first idea was about speed.
113
If we make things closer together, they move more slowly and if we make them further apart, they move more quickly.
114
Our second idea is about spacing and acceleration.
115
If we gradually get closer and closer together or further and further apart, things feel like they're slowing down or getting faster.
116
The third idea is about squash and stretch
117
and how using it can add a bit of life to your motion
118
and also give the audience a sense of what your objects are made of.
119
The fourth idea is about adding anticipation to your motion this will help build up energy
120
and sometimes add clarity our fifth idea is overshoot this is
121
where we let objects bounce back after a big movement
122
and our sixth idea is about arcs this is where we decide
123
if we want our motion to follow a straight line
124
or a more natural flowing arc through space
125
so the question is how do we use all of these ideas at the same time
126
if you're working on an animation you can ask yourself how does this motion feel?
127
The answer could be anywhere from it's great I love it to could be better
128
or it could just be this feels wrong.
129
If your answer is anything other than great I love it you can use these ideas to start asking questions
130
that will help improve your animation.
131
Does the speed feel right?
132
Should we change the spacing to adjust the acceleration?
133
Should we be using some squash or stretch?
134
Or maybe we need some anticipation?
135
Are the arcs working well?
136
Or do we need some overshoot to help sell the weight?
137
I'm going to walk through a simple animation now
138
and use these questions to help push our animation to the great I love it part of the graph here.
139
So for this animation, I'm trying to make a ball jump in the air
140
and land on the other side of the screen.
141
Let's just move the ball upwards, upwards, upwards, and then come back down again.
142
It takes 1 second or 24 frames to get to that point, and let's play it back at full speed.
143
Now if I ask myself how does this motion feel, I'd say not that great.
144
It feels unnatural, it feels stiff, it doesn't have any weight to it.
145
So this is where we can start asking those questions and apply those animation ideas that we've been talking about.
146
I'll start with the most obvious thing, to me at least.
147
I think this motion could use an arc.
148
If I imagine a cannibal flying through the air, I don't imagine a straight line up and a straight line down.
149
I picture more of an arc.
150
This is because it's being affected by gravity.
151
So let's add an arc to this motion.
152
Okay, so I think that's starting to feel better straight away.
153
Let's see what other ideas we can start working into this animation.
154
I think we could use some squash to create an anticipation
155
so it feels like the ball is building up energy before the jump I think
156
that we could exaggerate the acceleration by using a couple of
157
frames of stretch in the fastest part of the motion
158
And we could also use a bit of squash to create an overshoot
159
when the ball lands This will give it a bit more weight and make it feel a bit more springy Okay,
160
I think that's looking even better.
161
It's a totally usable piece of animation.
162
But if I ask myself one more time, how does this motion feel, I'd say it falls into this area here.
163
So if I look at these ideas again, I can think about which ideas I could exaggerate even more.
164
I think that we could push the anticipation even further, so it feels like it's shaking and building up energy just before it jumps.
165
I think that I could fine -tune the spacing a little bit more
166
so that the acceleration is clearer as it leaves the ground, and I think that I could exaggerate the overshoot even more by adding a stretch frame.
167
This means that it'll have a kind of double overshoot, making it feel really springy.
168
And this is the final result.
169
I think that it's got a lot more energy and personality now.
170
And that's it, six of the biggest ideas in animation
171
and how to start applying them to any animation you want to make.
172
Thanks for sticking with me.
173
Now for some homework.
174
Choose an animation medium, It could be anything from a flipbook to a program
175
that you're learning and take one of the six ideas we've talked about here today, like anticipation or arcs, and create a short animation based on that,
176
maybe one to two seconds long.
177
Then take a different idea, maybe squash or stretch, and create a second animation, once again, one to two seconds long.
178
And lastly, create a short animation that uses both of these ideas at the same time.
179
Hopefully you've enjoyed this crash course.
180
We'll be looking at these individual ideas and many more in future episodes.
181
See you next time.

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
