🖌️2D Animation Unit 7 – Follow Through and Overlapping Action

Follow through and overlapping action are essential principles in animation that bring characters and objects to life. These techniques add realism and believability by mimicking how different parts of a subject move at varying rates and times, creating fluid and dynamic motion. Mastering these concepts is crucial for animators to create engaging visuals. By understanding how to apply follow through and overlapping action, artists can convey weight, momentum, and flexibility in their animated subjects, avoiding stiff or mechanical movements that can make animations feel lifeless.

What's the Deal with Follow Through and Overlapping Action?

  • Fundamental principles in animation that bring characters and objects to life
  • Follow through refers to how parts of an object or character continue moving after the main body has stopped
  • Overlapping action describes how different parts of a character or object move at different rates and times
  • These principles add realism and believability to animated motion
  • Without follow through and overlapping action, animations can appear stiff, mechanical, and lifeless
  • They help to convey the illusion of weight, momentum, and flexibility in animated subjects
  • Mastering these concepts is crucial for creating fluid, dynamic, and engaging animations

Key Principles: Breaking It Down

  • Follow through is based on the concept of inertia, where parts continue moving due to their mass and velocity
    • Examples include a character's hair, clothing, or tail continuing to move after they stop
    • The speed and duration of follow through depends on the weight and flexibility of the parts
  • Overlapping action involves different parts of a character or object moving at different times and speeds
    • This creates a sense of natural, organic motion rather than everything moving in perfect unison
    • Examples include a character's arms, legs, and head moving at slightly different rates when walking or running
  • Drag is another key principle related to follow through, where parts lag behind the main body due to air resistance or friction
    • This is often seen in long hair, capes, or loose clothing trailing behind a moving character
  • Anticipation is the preparation for a major action, and it can be enhanced by follow through and overlapping action
    • A character may crouch down (anticipation) before jumping, and their hair and clothing will follow through after the jump

Real-World Examples: Where You've Seen It

  • Disney and Pixar animations are known for their masterful use of follow through and overlapping action
    • In "The Incredibles," Elastigirl's stretchy body demonstrates exaggerated follow through and overlapping action
    • Sulley's fur in "Monsters, Inc." is a prime example of follow through, as it continues to move and settle after he stops
  • Traditional hand-drawn animations also rely heavily on these principles
    • The flowing dresses in "Sleeping Beauty" and "Cinderella" showcase follow through and overlapping action
    • In "The Lion King," Simba's mane and tail demonstrate these principles in action
  • Even in stop-motion animation, follow through and overlapping action are crucial
    • The clay characters in "Wallace and Gromit" and "Shaun the Sheep" display these principles through their malleable bodies
  • In video games, characters and objects often utilize follow through and overlapping action
    • The iconic red scarf of the protagonist in "Journey" is a standout example of follow through in gaming

Techniques: How to Pull It Off

  • Timing is crucial in achieving effective follow through and overlapping action
    • Parts should start and stop moving at different times to create a sense of natural motion
    • Adjusting the spacing between frames can help control the speed and duration of follow through
  • Pose-to-pose animation can be used to plan out the main poses, with follow through and overlapping action added in between
    • This allows for greater control over the timing and placement of these principles
  • Straight-ahead animation can also be used, where each frame is drawn in sequence
    • This approach can lead to more fluid and organic follow through and overlapping action
  • Exaggeration is often used to emphasize follow through and overlapping action for stylistic or comedic effect
    • Animators may choose to exaggerate the amount or duration of follow through to convey a specific mood or feeling
  • Reference footage of real-world movements can help inform the timing and application of these principles
    • Studying how hair, clothing, and body parts move in reality can guide the animation process

Common Mistakes and How to Avoid Them

  • Overlooking follow through and overlapping action altogether, resulting in stiff and lifeless animation
    • Make a conscious effort to incorporate these principles into every animation
  • Applying follow through and overlapping action inconsistently throughout an animation
    • Establish rules for how different materials and body parts should move and stick to them
  • Making all parts move at the same speed and start/stop at the same time
    • Vary the timing and speed of different parts to create a more natural, organic look
  • Exaggerating follow through and overlapping action too much, leading to unrealistic or distracting motion
    • Find a balance between realism and stylization that suits the project's goals
  • Forgetting to consider the weight and properties of different materials when applying these principles
    • A heavy, rigid object will have less follow through than a light, flexible one

Tools and Software: Making Your Life Easier

  • Most 2D animation software includes tools to help with follow through and overlapping action
    • Adobe Animate has a "Bones" tool that allows you to create a simple skeleton for your character, making it easier to animate overlapping action
    • Toon Boom Harmony has a "Deform" tool that lets you create a mesh for your character, which can be used to create follow through effects
  • Onion skinning is a feature in many animation programs that allows you to see multiple frames at once
    • This can be helpful in visualizing and timing follow through and overlapping action
  • Some software, like TVPaint, have built-in physics engines that can simulate follow through and overlapping action
    • This can be a quick way to rough in these effects, which can then be fine-tuned by hand
  • Plug-ins and scripts can also be used to automate or simplify the process of creating follow through and overlapping action
    • For example, the "Overlappy" plug-in for After Effects can help create overlapping action effects

Practice Exercises: Get Your Hands Dirty

  • Animate a simple pendulum swinging back and forth
    • Focus on the timing and spacing of the pendulum's motion to create a sense of weight and follow through
  • Create a walk cycle for a character with long hair or a tail
    • Pay attention to how the hair or tail moves in relation to the body, and how it continues to move after the body stops
  • Animate a flag waving in the wind
    • Consider how the fabric moves and folds, and how different parts of the flag move at different rates
  • Create a character jumping or leaping
    • Incorporate anticipation, follow through, and overlapping action to make the motion feel dynamic and realistic
  • Animate a character with loose clothing performing a dance or acrobatic move
    • Think about how the clothing moves in relation to the body, and how it continues to move after the character stops

Taking It Further: Advanced Tips and Tricks

  • Combine follow through and overlapping action with other animation principles like squash and stretch or secondary action
    • This can create even more dynamic and interesting animations
  • Experiment with different timing and spacing patterns to create unique and expressive follow through and overlapping action
    • Varying the easing or adding holds can dramatically change the feel of the animation
  • Study live-action footage frame-by-frame to analyze how follow through and overlapping action occur in the real world
    • This can help you develop a deeper understanding of these principles and how to apply them effectively
  • Practice animating different materials (hair, cloth, metal, etc.) to get a feel for how they move differently
    • This will expand your skillset and make your animations more versatile
  • Collaborate with other animators and get feedback on your use of follow through and overlapping action
    • Fresh perspectives can help you identify areas for improvement and refine your techniques
