THE MOTION FIELD GUIDE

A shared language
for better motion.

Plain-English definitions of Lottie, Bodymovin, SVG, Rive, GSAP, state machines, micro-interactions and animation delivery terms.

A motion brief is easier to review when everyone uses the same vocabulary. These short definitions explain the formats, interactions and handoff terms that come up in web animation projects.

Lottie
An animation format and player ecosystem used to render exported motion on websites and in apps.
Bodymovin
An After Effects extension commonly used to export Lottie-compatible animation data.
dotLottie
A container format for packaging animation data and related assets; the selected player must support it.
SVG
Scalable Vector Graphics: a vector image format that can be styled and animated on the web.
Rive
A design and animation tool with runtimes for interactive graphics, including state-machine playback.
GSAP
A JavaScript animation library used to coordinate properties, timelines and interactive motion.
State machine
A model that defines visual states and the transitions triggered by inputs or conditions.
Micro-interaction
A small piece of feedback around a user action, such as acknowledging a click or a successful save.
Empty state
The interface shown when there is no content yet, often used to explain the next useful action.
Reduced motion
A user preference to minimize nonessential movement. Provide a static or quieter experience when it is enabled.
Motion handoff
The assets, specifications and implementation notes delivered so a developer can integrate an animation correctly.
File budget
An agreed size limit for a deliverable. It should be tested alongside rendering cost and runtime overhead.
