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.
