Secondary action in animation is a critical principle that breathes life into animated characters and scenes. It refers to the subtle, complementary movements or gestures that occur alongside the primary action, enhancing the storytelling and emotional depth. For example, when a character walks, their arms might swing naturally, or their facial expressions might convey their mood—these are examples of secondary action in animation.

This principle is one of the 12 fundamental animation principles established by Disney animators, Frank Thomas and Ollie Johnston, to elevate the quality of animations. Secondary action in animation is not just about adding complexity; it’s about creating a richer, more engaging experience for the audience. By introducing secondary movements, animators can provide additional context, emphasize emotions, and make characters appear more realistic and relatable.

This article will explore the importance of secondary action in animation, how it differs from primary action, and practical tips to incorporate it into your work.

The Role of Secondary Action in Animation

Secondary action in animation plays a pivotal role in enhancing the visual appeal and storytelling of any animated scene. By complementing the primary action, it adds depth, realism, and emotional resonance, making animations more engaging and memorable. Let’s delve deeper into the significance of secondary action in animation:

Enhancing the Main Action

The primary purpose of secondary action in animation is to support and amplify the main action. While the primary action drives the narrative—such as a character running or jumping—the secondary action adds subtle nuances that make the scene feel natural and believable. For instance, when a character waves their hand, a secondary action might include their hair swaying slightly or their clothing fluttering with the movement. These details enrich the animation without distracting from the primary focus.

Adding Depth and Realism

Without secondary action, animations can appear stiff or mechanical. Secondary actions introduce fluidity and a sense of natural movement that resonates with how objects and beings behave in the real world. For example, when a character laughs, their shoulders might rise and fall, and their hands might gesture expressively. Such secondary motions make the character’s emotions and actions more convincing, drawing the audience into the story.

Expressing Personality and Emotion

Secondary action in animation is an excellent tool for conveying personality traits and emotions. A shy character might fidget with their hands or avoid direct eye contact as secondary actions, while a confident character might have bold, exaggerated gestures. These actions provide non-verbal cues that reveal more about the character’s personality and mood, enriching the narrative without relying solely on dialogue or primary movements.

Creating Visual Interest

In dynamic scenes, secondary action in animation helps maintain the viewer’s attention by introducing layers of movement. For instance, in a battle sequence, the swish of a cape or the scattered debris adds complexity without overshadowing the main action. These additional elements keep the scene visually stimulating, ensuring the audience remains captivated.

In summary, secondary action in animation is a subtle yet powerful principle that enhances storytelling, realism, and emotional impact. By carefully incorporating these complementary movements, animators can elevate their craft and create animations that resonate deeply with viewers.

Difference Between Primary and Secondary Action

In animation, understanding the distinction between primary and secondary action is crucial for creating dynamic and realistic sequences. While both are essential components of animation, they serve different purposes and work together to tell a compelling story. Here’s a breakdown of their differences:

1. Definition

• Primary Action:
  Primary action refers to the main movement or action that drives the narrative. It is the core motion that conveys the primary intent or purpose of a character or object in a scene. For example, a character walking, jumping, or throwing an object represents primary action.
• Secondary Action:
  Secondary action, on the other hand, complements the primary action. It involves additional movements that add depth, context, or personality to the scene. For instance, while a character is walking (primary action), their swinging arms or bouncing hair would be the secondary action.

2. Purpose

• Primary Action:
  The primary action is responsible for advancing the story. It ensures that the main focus of the scene is clear and directs the audience’s attention to the critical elements of the narrative.
• Secondary Action:
  Secondary action enhances the primary action by adding layers of realism and detail. It provides subtle cues about a character’s emotions, environment, or personality without overshadowing the primary focus.

3. Impact on Storytelling

• Primary Action:
  Primary action is essential for the audience to understand what is happening. It is the foundation of the scene, ensuring the animation serves its storytelling purpose effectively.
• Secondary Action:
  Secondary action enriches the storytelling by adding texture and nuance. It helps express emotions, establish mood, and make the scene more engaging and relatable.

4. Examples

• Primary Action Examples:

• A character swinging a bat.
• A bird flying across the sky.
• A car accelerating on a road.
• Secondary Action Examples:

• The character’s hair swaying with the motion of the bat.
• The bird’s feathers rippling in the wind.
• The car’s tires kicking up dust as it speeds up.

5. Dependency

• Primary Action:
  Primary action exists independently and can stand on its own to communicate the main idea of the scene.
• Secondary Action:
  Secondary action depends on the primary action. It cannot exist without the main motion as it is intended to complement and enhance it.

The primary action provides the foundation of movement and narrative, while secondary action in animation adds the fine details that elevate the scene. Together, they create animations that are both clear in intent and rich in storytelling, ensuring an immersive experience for the audience.

Examples of Secondary Action in Animation

Secondary action in animation enriches scenes by adding complementary movements that bring realism and depth. These subtle yet impactful actions enhance the narrative and make characters and environments more engaging. Here are some common examples of secondary action in animation:

1. Facial Expressions

While a character performs a primary action like speaking, their facial expressions can act as a secondary action. For instance, a smile, raised eyebrows, or a frown adds emotional depth and helps convey their feelings.

Example:
A character delivers a powerful speech (primary action) while their eyes widen and lips curl into a slight smile, reflecting their enthusiasm (secondary action).

2. Arm and Hand Movements

When a character walks or runs, their arms naturally swing as a secondary action. Similarly, subtle hand gestures can accompany dialogue or emotions.

Example:
A character waving goodbye (primary action) while their other hand adjusts their hat or a bag slung over their shoulder (secondary action).

3. Clothing or Accessories Movement

The swaying of a character’s clothing, jewelry, or accessories in response to their primary action adds realism and a sense of motion.

Example:
As a character dances (primary action), their scarf flows in the air, reacting to their movements (secondary action).

4. Body Movements

Secondary action often includes movements that reflect a character’s emotional state or personality, such as a nervous twitch or confident posture.

Example:
A nervous character fidgets with their fingers (secondary action) while explaining a plan (primary action).

5. Environmental Interactions

Secondary action is not limited to characters; objects in the environment can also react to primary actions.

Example:
A character slams a door (primary action), and a nearby picture frame wobbles or falls off the wall (secondary action).

6. Animal and Creature Behavior

In animations featuring animals, secondary actions like tail movements, ear flicks, or breathing add realism.

Example:
A dog runs across a field (primary action), while its tail wags energetically and its ears flop with each step (secondary action).

7. Hair or Fur Movement

Hair and fur can provide natural secondary action, reacting to the motion of characters or environmental factors like wind.

Example:
A character jumps from a high ledge (primary action), and their hair trails behind them, catching the breeze (secondary action).

8. Object Movements

When characters interact with objects, these objects can display secondary actions that enhance realism.

Example:
A character picks up a glass (primary action), and the liquid inside swirls gently in response (secondary action).

These examples demonstrate how secondary action in animation complements primary movements, enhancing realism and storytelling. By carefully incorporating these subtle actions, animators can create scenes that resonate deeply with audiences.

Techniques for Implementing Secondary Action in Animation

Mastering secondary action in animation requires thoughtful planning and execution. These actions must enhance the primary movement without overshadowing it. Here are proven techniques to effectively implement secondary action in animation:

1. Plan with Storyboards and Animatics

• Start by visualizing the primary action through storyboards or animatics.
• Identify opportunities where secondary action can enhance the scene.
• Ensure the secondary action aligns with the story’s tone and character’s personality.

Example: If a character is running, plan secondary actions like their hair bouncing or their clothing flapping in the wind to complement the motion.

2. Layer Movements Sequentially

• Animate the primary action first to establish the core movement.
• Add secondary action as a separate layer, ensuring it doesn’t interfere with the main action.
• This approach helps maintain clarity and balance between the actions.

Example: Animate a character swinging a sword (primary action) before adding details like their cape billowing (secondary action).

3. Use Timing and Spacing Effectively

• The timing of secondary actions should be slightly offset from the primary action to create a natural, organic feel.
• Ensure secondary actions follow principles like “follow-through” and “overlapping action” to enhance realism.

Example: When a character claps, their hands (primary action) might cause ripples in their sleeves or bracelets that lag slightly behind (secondary action).

4. Reflect Character Personality

• Tailor secondary actions to the character’s personality, emotions, and traits.
• Shy characters might fidget or avoid eye contact, while confident ones may have bold, exaggerated gestures.

Example: A mischievous character might smirk (secondary action) while sneaking away (primary action), adding layers to their personality.

5. Add Secondary Action to Objects and Environment

• Incorporate secondary movements in objects or environmental elements affected by the main action.
• This technique adds realism and helps blend characters seamlessly into their surroundings.

Example: A character slamming a door might cause nearby curtains to sway or a stack of papers to fall over.

6. Keep Secondary Action Subtle

• Secondary action should enhance the scene without drawing attention away from the primary action.
• Overly pronounced secondary movements can confuse viewers and detract from the main focus.

Example: A character sipping coffee (primary action) might lightly tap their fingers on the cup (secondary action), keeping it subtle yet effective.

7. Test and Iterate

• Review the animation frequently to ensure secondary actions feel natural and cohesive.
• Seek feedback from peers or test audiences to refine the balance between primary and secondary actions.

Example: During playback, ensure that a character’s bouncing ball (primary action) and trailing shadow (secondary action) are synchronized and visually appealing.

8. Use Physics to Your Advantage

• Apply principles of physics, like inertia and gravity, to secondary actions for added realism.
• Objects like hair, clothing, and accessories should move naturally based on the forces acting on them.

Example: When a character stops abruptly, their scarf (secondary action) should continue moving forward slightly before settling down.

Implementing secondary action in animation involves a blend of planning, creativity, and technical skill. By layering movements, perfecting timing, and reflecting character traits, you can create animations that are dynamic, engaging, and realistic.

Secondary Action in Different Animation Styles

Secondary action is a versatile principle that enhances the storytelling and realism of animations across various styles.

Examples:

• A character jumping (primary action) with their shoelaces fluttering or water splashing under their feet (secondary actions).
• A bouncing ball causing a ripple effect on a puddle it lands in.

Techniques:

• Physics-based simulations for elements like cloth, hair, and water.
• Animating secondary actions on separate layers to maintain control over their timing and intensity.

3. Stop-Motion Animation

Stop-motion animation relies on physical objects, making secondary actions both a creative and technical challenge. Subtle secondary actions can make scenes feel more lifelike.

Examples:

• A puppet character’s clothes shifting slightly as they move.
• Environmental interactions, such as dust particles or leaves reacting to a character’s movement.

Techniques:

• Adjusting props and objects frame-by-frame to achieve realistic motion.
• Using additional materials like flexible wires for controlled secondary movements.

4. Motion Graphics

In motion graphics, secondary action often involves abstract shapes, typography, or visual elements that complement the main narrative or motion.

Examples:

• Text sliding in (primary action) while a shadow or glow trails behind (secondary action).
• A spinning logo causing smaller elements around it to ripple or rotate.

Techniques:

• Layered animations to create harmony between the main motion and secondary elements.
• Easing and timing adjustments for smooth and synchronized effects.

5. Anime and Stylized Animation

Anime often incorporates exaggerated primary actions, making secondary actions a vital tool for enhancing dramatic and emotional impact. Stylized animation, in general, uses secondary actions to amplify artistic expression.

Examples:

• A character’s scarf dramatically blowing in the wind as they strike a heroic pose.
• Sweat droplets or sparkles accentuating a character’s emotions.

Techniques:

• Emphasizing artistic exaggeration to fit the style.
• Combining digital effects with hand-drawn details for added flair.

6. Experimental and Abstract Animation

In experimental animation, secondary action can take unconventional forms, such as abstract shapes or color changes that respond to the main motion.

Examples:

• A geometric shape expanding and sending out ripples of smaller shapes.
• A character’s movements causing dynamic shifts in background colors or patterns.

Techniques:

• Creative use of software tools like particle systems or dynamic brushes.
• Exploring unconventional visual languages to represent secondary actions.

Secondary action adapts to the requirements of various animation styles, from realistic simulations in 3D animation to exaggerated movements in anime. Understanding how to implement these actions based on the chosen style ensures animations are not only visually engaging but also emotionally resonant.
