Production guidance for assessing, exporting, packaging, integrating, capturing, validating, and handing off Lottie vector animations. Use for Bodymovin/Lottie JSON, dotLottie archives, renderer and player compatibility, fonts and glyphs, image assets, markers and segments, deterministic video capture, responsive sizing, optimization, accessibility, and cross-platform QA; not for general After Effects animation craft or live-action/video delivery.

# Lottie animation delivery

Use this skill when a designed vector animation must move reliably from an authoring tool into web, mobile, application, or rendered-video players. The production problem is interchange: preserving intended motion, typography, assets, timing, accessibility, and control across implementations with different feature support.

Lottie is not a universal After Effects renderer. Treat the target-player matrix as an input before animation is finalized, not as a test performed only after export.

## Evidence and volatility

- **Documented fact:** behavior from the official Lottie specification, lottie-web, dotLottie specification, W3C, or browser documentation.
- **Production heuristic:** a practical default that must be tested against target players and the design.
- **Empirical observation:** a measured result from an exported file, player fixture, device, frame capture, or final delivery.

Facts were checked **2026-07-12**. The official Lottie specification describes itself as a work in progress. Player feature support, exporter options, dotLottie versions, state machines, themes, and package APIs can change. Record exact exporter/player versions and re-check their current documentation.
