Portable templates
Raw JSON, TypeScript builders, batch jobs, preview, and future editor surfaces compile to the same versioned Kavio composition format.
JSON-first programmable video
Kavio
Portable video templates for automation, AI generation, cinematic motion, browser preview, and future visual editing.
Project
One composition format from JSON to preview.
Frame-based timeline
Deterministic timing keeps validation, preview, exports, and automated render jobs aligned around stable frame boundaries.
Pre-release engine
Schema, validation, native transitions, masks, text motion, browser preview, render-worker contracts, FFmpeg planning, and CLI tools are in place.
Workflow
Author once, expand across formats.
A Kavio template declares props, assets, layers, audio, and export presets. Batch rendering combines one template with prop rows and export presets to create stable output jobs.

Getting started
Install, build, validate, inspect, and preview.
Concepts
Composition, frames, props, assets, exports, and batch jobs.
Authoring
Write reusable templates with JSON or the builder SDK.
CLI reference
Command behavior, JSON output, and render status.
Browser preview
Scrub frames, play timelines, transition series, masks, and export overrides.
Rendering
Browser-backed MP4 rendering with motion budgets and current limits.
MCP and AI plugins
Agent tools, portable skill, plugin bundle, render boundary, and safety model.
Examples
Fixtures that show the engine in motion.
basic-json
Small raw composition for CLI validation, inspection, and preview.
basic-builder
TypeScript builder sample that emits the same JSON as the raw fixture.
mvp-demo
Template expansion across five prop rows and three export presets.
motion-showcase
Transition series, masks, kinetic type, and cinematic helper output in one renderable reel.
kavio-promo all motions
Self-promo reel covering every motion family with mobile website proof.
masks-text-motion
Procedural masks, inverted shape masks, scramble text, and type-on captions.
visual-fixtures
Fixed-frame browser-renderer regression material and DOM snapshot.
Packages
Small packages with clear ownership.
