Procedural animationThere are short films that are procedurally
produced.No feature length animation that is entirely
procedural animation. Procedural animation is often used as effect
animation for live action films and 3D computer animations.

Keyframe is a drawing (image) of a key moment in an animation sequence, where the motion is at its extreme
Inbetweens fill the gaps between keyframes
Keyframe animation

In traditional animation, skilled animators draw keyframes; less experienced animators draw inbetweens
In 3D computer animations, animators set up parameter values for keyframes; software interpolates parameter values between keyframes for inbetweens
Every motion is created by animators

Different interpolation methods create different timing

Linear interpolation
Spline interpolation

What is motion capture?
Sampling and recording motion of humans, animals, and inanimate objects s 3D data
Data can be applied to 3D computer models
Motion capture animation

Faster to produce animation than keyframing (if an established production pipeline exists)
Secondary motions and all the subtle motions are captured, providing more realism
Motion capture animation

Motion is generated by a procedure, a set of rules
Animator specifies rules and initial conditions and runs simulation
Procedural animation

Provides more realism in natural phenomena than keyframing
Frees animators from generating complex objects and keyframing a large number of objects
Procedural animation

Used for effect animation for traditional animation and live action films as well as for 3D computer animation

A combination of keyframe animation, motion capture and/or procedural animation is often used to produce animations
