A Fundamental Aspect of Animation Basics:
Everything about Inbetweening

Why is it important to learn inbetweening
before tackling key animation poses?

If you can’t draw inbetween animations
that connect movement smoothly,
it is merely illustration,
not animation.

In order to master the most crucial aspect of inbetweening,
which ultimately determines the quality of the final motion,
Studio Ppuri, one of Korea’s top 2D animation production companies,
is providing a practical basic guide
based on the actual 2D animation production process,
led by animation director Boksim Kim.

In this class, you will learn
all the essential and valuable information
that hasn't been taught elsewhere,
starting from the basics of animation terminology
and reading key exposure sheets
to understanding orientation and directed lines
for various inbetween expressions.

Our comprehensive 2D animation inbetweening class helps you
to acquire the skills to master natural movement in animation.
You'll learn how to create character movements at different angles,
natural effects like smoke and fire, and much more.

Boksim Kim

Hello, I’m Boksim Kim, an inbetween animator.

I have been in charge of the cell animation
and digital animation departments for a long time,
and have mainly participated in Japanese
and American TV series and movies,
as well as domestic productions.
Afterwards, I was dispatched to China
for about 3 years as a supervisor
and currently, I am actively working
based on accumulated practical experience.

In this class, we'll cover the foundational skills
of inbetween animation
and checking tasks using TVPaint software.
You'll get a thorough understanding of these skills
and be able to apply them immediately
in practical work situations.

Question. 01
Why is inbetweening important
in animation?

Animating is not an individual task. In the animation industry, collaboration and communication are crucial. In order to produce a seamless product, it is essential to have a clear understanding of the animation process, particularly inbetweening, before starting the keyframe animation. Simply having good drawing skills is not enough for inbetweening; it is also necessary to have a solid grasp of basic skills such as reading exposure sheets and separating cells to avoid problems in the later stages and achieve high-quality animation.

Question. 02
As a director of inbetween animation,
what do you consider to be your strengths?

My strength lies in preserving the intricate details of characters based on a deep understanding of visual art. Furthermore, I have been working in the animation industry since 1996, starting with traditional paper animation. Over the years, this experience has helped me develop a keen sense of creativity in the digital environment using TVPaint software. In this class, I aim to share this expertise in detail.

Question. 03
What are the key aspects of this class?

Animation is a time-consuming process, particularly in the area of inbetweening, making time efficiency a critical aspect of the workflow. Thus, before diving into this field, it is important to build a foundation of basic skills such as line work, artwork tracing, and inbetweening, as well as mastering the fundamentals of using TVPaint for animation. This class will provide practical guidance to efficiently apply these skills in professional settings and help students excel in their careers.

Question. 04
Who would you recommend
this class to?

This class is recommended for beginners and aspiring animators who want to build a foundation in 2D animation skills and gradually apply them to various commercial animation projects. It is also suitable for students majoring in animation, new graduates, and anyone interested in learning professional animation skills for practical use in the industry, as well as those who are curious about digital animation production or seeking more efficient workflows and error correction methods.
