12 principles of animation: All about Straight Ahead & Pose To Pose
12 principles of animation - The illusion of life
During the 30s of the last century, as pioneers in their field, Walt Disney and his associates (Frank Thomas, Ollie Johnston, and others) created and developed a list – 12 principles of animation. Published in the book "The Illusions Of Life", this is what has laid the foundation and core direction of the animation industry throughout its nearly century-long history.
Being a pioneer with great enthusiasm and passion, Disney did not invent these 12 principles out of the blue. Instead, it was the result of a lengthy process of comprehending, analyzing, and summarizing a myriad of Walt Disney Studios’ experiments.
Disney wanted to find ways to create “real” and “soulful” motions, and even convey the essence as well as the character’s personality through them – a truly ambitious vision especially during the infant stage of the animation industry.
Although nearly 100 years have passed, we still view these 12 principles of animation as a "bible" for animation enthusiasts. Throughout that time course, all the animation that we have ever seen, including every iconic film and movie character, were built based on Walt Disney’s framework.
Even nowadays, those principles have all been so fully presented to the animators in the training process that there is no need to explain “anticipation” or “follow-through” in a discussion. In other words, the 12 principles of animation have subconsciously become a common language among animators.
With the next series of articles in “The Animation Study”, DeeDee Animation Studio will give you an overview of what laid the foundation for the animation industry as we know it today. If you’ve read about the first three principles: Squash and stretch; Anticipation, Staging, let’s move to the fourth one: Straight Ahead & Pose To Pose.
Principles of animation - Straight Ahead & Pose To Pose
Straight-Ahead & Pose-to-pose are two different methods of creating motion in animation. Let's learn more about each method with DeeDee!
What are Straight Ahead & Pose To Pose?
Straight Ahead: The straight-ahead technique means to animate one drawing after another back to back in sequential order.
Pose to Pose: The pose-to-pose technique is a bit different as it means to draw the key poses first and then fill in the inbetween drawings to smooth out the animation later.
Other related terms:
Keyframes: The most important drawings that define the starting and ending point of any particular movement.
Breakdown: Drawings between two keyframes determine the direction of movement
Extremes: Commonly used for both Keyframes and Breakdown
Applications in animation
Pose to pose:
This is the most popular approach in animation (2D hand-drawn, 3D, etc). Pose-to-pose allows animators to tightly and effectively control the stages of production. Usually, using the straight-ahead method is much harder to keep the scale of the characters and objects consistent. It’s more time-consuming if you want to go back to do any retake when you’re already finished.
When compared to straight-ahead, pose-to-pose is a bit intricate but more efficient. If from the beginning, animators can figure out the shapes and order of drawings then they should apply the pose-to-pose method. Finalize the keyframes first, adjust them if needed, then decide on the character's movement through breakdowns, then insert the inbetweens.
With the pose-to-pose method, animators can easily identify the key poses as well as the main problems. It is more efficient when it comes to doing slow-motion with emphasis on the character’s facial expression. This method helps animators focus on details and control the sequence.
The below video will give you a vivid example of this method.
The advantage of straight ahead can be seen in animating objects that do not have solid states such as flames, water drops, or dust, etc. Such natural effects are flexible. However, animators can still apply pose-to-pose to add in the inbetweens to create smoother transitions.
In many other cases, animators can combine two methods to handle overlapping motions. For example, you have to draw a running rabbit, you can apply the pose-to-pose technique with the body then use straight ahead to draw the physical movement of the rabbit’s ears. This approach can also be applied to animate hair, tails, and other extra details.
In addition, straight ahead is also applied in stop motion materials (puppet animation, paper cut-out, etc). With "real-life" materials, it is very difficult for an artist to build keyframes by using the pose-to-pose method and then insert breakdowns and inbetweens in the middle like 2D or 3D. Therefore, before making a certain scene in a stop motion animated film, animators will have to prepare and calculate the movement very carefully to avoid mistakes.
It can be said that the two methods of straight-ahead & pose to pose are important skills that any animator needs to master. Applying a combination of these two methods helps animators to create vivid movements for the characters.
