Animation Vocabulary in English
20 essential animation words with definitions and example sentences — frames, rigging, and rendering for B2–C1 ESL learners.
Pedagogically reviewed by LexFizz Team
Animation vocabulary describes the creative and technical process of bringing drawings, models, or digital characters to life on screen. Words such as keyframe, rigging, and rendering carry precise meanings used across film, television, and video game studios. You can check the full entry for any of these terms in the Cambridge Dictionary.
This page covers 20 key animation words used in production studios, tutorials, and reviews of animated films and games. These terms appear whenever animators discuss their workflow, tools, or techniques.
Unlike our broader Film and Cinema vocabulary and Video Games vocabulary pages, this list focuses specifically on the techniques used to create movement and character performance frame by frame. Mastering this vocabulary will help you follow behind-the-scenes documentaries, read production credits, and discuss animation with confidence.

| keyframe | a frame that defines the starting or ending point of a smooth transition or movement | The lead animator drew the keyframes first, leaving the in-between poses for later. | B1 |
| in-between | a frame drawn or generated between two keyframes to create smooth motion | Junior animators traditionally drew the in-betweens under the supervision of a senior artist. | B2 |
| storyboard | a series of drawings that plan out the shots, action, and camera angles of a scene before production | The director reviewed the storyboard carefully before any animation work began. | B1 |
| rigging | the process of creating a digital skeleton and controls that allow a 3D character model to move | Good rigging lets an animator pose the character's arms and face with precise control. | C1 |
| rendering | the process of generating the final image or video from a 3D scene, including lighting and textures | The final rendering of the complex scene took several hours per frame. | B2 |
| motion capture | a technique that records the movements of a real actor and applies them to a digital character | The studio used motion capture to give the creature's movements a realistic feel. | C1 |
| timeline | the software interface showing frames, keyframes, and layers in sequence over time | She scrubbed through the timeline to check the character's movement frame by frame. | A2 |
| cel | a traditional transparent sheet used to draw individual animated characters, layered over a background | Classic hand-drawn films were created by painting characters onto celluloid cels. | B1 |
| stop-motion | an animation technique in which physical objects or models are moved slightly and photographed one frame at a time | The studio is famous for its detailed stop-motion films using handmade puppets. | B2 |
| rotoscoping | a technique in which animators trace over live-action film footage frame by frame to create realistic movement | Rotoscoping gave the animated dancers unusually fluid and realistic motion. | C1 |
| character design | the process of creating the visual appearance, proportions, and personality of an animated character | The character design went through dozens of revisions before the final look was approved. | B1 |
| sprite | a small two-dimensional image or animation used to represent a character or object, especially in video games | The player's sprite changed animation as soon as the jump button was pressed. | B1 |
| lip sync | matching a character's mouth movements accurately to recorded spoken dialogue | Poor lip sync can make even great voice acting feel unconvincing on screen. | B1 |
| easing | the gradual speeding up or slowing down of a movement, rather than constant speed, to look natural | Adding easing to the bouncing ball made its motion feel far more realistic. | B2 |
| walk cycle | a short, repeating sequence of frames showing a character walking, designed to loop seamlessly | Animators often perfect a basic walk cycle before tackling more complex character actions. | B1 |
| compositing | combining multiple visual elements, such as characters, backgrounds, and effects, into a single final image | Compositing brought together the hand-drawn character and the digitally painted background. | C1 |
| voice-over | recorded spoken dialogue performed by an actor, added to an animated character or scene | The animators timed the character's expressions to match the recorded voice-over exactly. | A2 |
| render farm | a large network of powerful computers used to process and complete rendering jobs quickly | The studio's render farm worked through the night to finish the final scenes on schedule. | C1 |

Frequently Asked Questions
What is animation?
Animation is the technique of creating the illusion of movement by displaying a rapid sequence of still frames, whether hand-drawn, model-based, or created with 3D software. It is used in films, television, video games, and advertising.
What is the difference between a keyframe and an in-between?
A keyframe marks an important pose or moment, such as the start or end of a movement. An in-between is a frame created to smoothly connect two keyframes, filling in the motion so the transition looks natural rather than jumpy.
What is rigging in 3D animation?
Rigging is the process of building a digital skeleton, along with controls, inside a 3D character model. This rig allows an animator to pose and move the character's limbs, face, and body realistically, without needing to reshape the model manually for every frame.
What is the difference between motion capture and rotoscoping?
Motion capture records the actual movements of a real actor using sensors, then applies that data directly to a digital character. Rotoscoping instead has an animator manually trace over live-action footage frame by frame, producing a more stylised but still realistic result.
What is a storyboard used for?
A storyboard is a series of drawings showing the planned shots, actions, and camera angles of a scene before full animation begins. It helps a director and team plan pacing and composition early, avoiding costly changes later in production.
What is compositing?
Compositing is the process of combining multiple separate visual elements — such as characters, backgrounds, lighting effects, and text — into a single finished image or shot. It is often one of the final steps before a scene is considered complete.
What does easing mean in animation?
Easing refers to the gradual acceleration or deceleration of a moving object or character, rather than constant, mechanical-looking speed. Natural motion in the real world almost always eases in and out, so animators add this effect to make movement feel believable.
What is stop-motion animation?
Stop-motion is a technique where physical models, puppets, or objects are moved slightly and photographed one frame at a time. When played back in sequence, these individual photographs create the illusion of continuous movement.
Is animation vocabulary useful for English learners?
Yes, especially for learners interested in film, gaming, or digital media, since animation vocabulary appears in production credits, tutorials, and behind-the-scenes documentaries. Many terms, like rendering and timeline, are also used more broadly in digital creative software.
Which animation words should I learn first?
Start with the basics: animator, frame, keyframe, and storyboard. Then learn technical production terms such as rigging, rendering, compositing, and motion capture, which describe how a finished animated scene is created.
