An animator creates and controls the movement of characters, objects, environments, graphics or other visual elements over time. Animators can work in traditional hand drawn animation, stop motion, two dimensional digital animation, three dimensional computer animation, visual effects, games, advertising, television, film and other media. Their central task is to determine how movement should look and feel, not merely to make an object change position. Animators control timing, spacing, posing, anticipation, weight, acceleration, expression, interaction and rhythm so that movement communicates physical properties, emotion and intention. The exact tools differ by medium, but the underlying responsibility is the design of movement.
In traditional animation, animators create drawings that represent key poses and actions. In modern two dimensional and three dimensional digital production, animators often work with keyframes and digital controls. A keyframe identifies an important state of an object or character, while software can generate intermediate frames through interpolation. The animator then adjusts the timing and movement so that the automatically generated motion produces the intended result. This means computer animation does not remove the animator's role. The software performs calculations, but the animator determines what the movement should communicate and continually edits the resulting motion.
Three dimensional character animation usually involves a digital model and rig. The model defines the visible character, while the rig provides an underlying control structure that allows the animator to manipulate limbs, joints, facial features and other components. Animators create poses and sequences using these controls. They must understand anatomy, balance, centre of gravity, body mechanics and acting principles even when the character is fictional or non human. A convincing walk, for example, requires coordinated movement of legs, hips, arms, torso and head, with timing that communicates weight and personality. The animator therefore combines technical software knowledge with observation of physical and behavioural movement.
Timing and spacing are fundamental animation concepts. Timing determines how many frames an action occupies, while spacing describes the distance between successive positions. Evenly distributed positions can create constant motion, whereas changing spacing can create acceleration and deceleration. A rapidly accelerating object can have widely changing positions between frames, while a slow movement can use closely spaced positions. Animators manipulate these relationships to communicate weight, force and intention. Anticipation prepares the viewer for an action, follow through allows parts to continue moving after a main action and overlapping action prevents every body part from appearing to move simultaneously.
Animators also perform a form of visual acting. Facial expressions, posture, gestures, eye direction and body language communicate character without spoken dialogue. The animator decides when a character looks, pauses, reacts or changes posture. Subtle movements can communicate hesitation or attention, while larger movements can communicate excitement, fear or physical exertion. The same action can be animated differently for different characters to establish personality. This is why character animation requires interpretation rather than simple mechanical reproduction. Animators may study acting, gesture drawing, biomechanics and observation to improve their ability to communicate intention through movement.
Animators work closely with other production departments. In film and television they may collaborate with directors, storyboard artists, character designers, layout artists, riggers, modellers, texture artists, lighting artists, effects artists, compositors and editors. In games, animators may work with programmers and technical artists to ensure that movement responds correctly to player input and game systems. Production constraints can affect animation because a scene may need to match camera movement, dialogue, visual effects or technical requirements. Professional animation is therefore usually collaborative, even when the final movement is attributed to an individual animator.
Different animation disciplines require different workflows. Stop motion animators physically reposition objects or puppets between photographs, while traditional animators create drawings. Two dimensional digital animators manipulate flat artwork, and three dimensional animators manipulate digital objects in virtual space. Motion graphics artists animate typography, shapes and graphic elements, while visual effects animators may create or modify movement within live action footage. Motion capture can provide recorded movement data that animators clean, modify or combine with keyframe animation. These methods can overlap, and productions often use more than one technique.
The professional animator's role is therefore to design readable, purposeful and technically achievable movement. The work requires artistic judgement, observation, timing, spatial understanding, software or physical production skills and collaboration. Animators must consider how movement interacts with camera framing, editing, sound and narrative. Their work can range from subtle facial motion to large scale action, from abstract graphic movement to realistic creature behaviour. Animation is consequently not simply the creation of individual images but the controlled construction of behaviour and motion across time, with the animator responsible for turning static assets, drawings or models into expressive moving performances.
