What problem does it solve? Writing Remotion videos requires frame-driven animation patterns, correct media handling, and deterministic rendering rules that differ from normal React development; this Skill supplies the domain knowledge needed to produce correct Remotion code. ## Core Features & Use Cases - Project scaffolding and composition setup: Create new Remotion projects, define compositions with width, height, fps, and duration, and compute metadata dynamically with calculateMetadata. - Animation and sequencing patterns: Animate with useCurrentFrame, interpolate, and Bézier easing, and control timing with Sequence, Series, and premounting. - Media and effects rules: Loadable rule files cover captions, subtitles, audio, video trimming, FFmpeg, silence detection, audio visualization, 3D with Three.js, Lottie, maps with MapLibre, fonts, transitions, and parameterized videos with Zod schemas. - Use Case: Ask the assistant to build a captioned promotional video with a voiceover, background music, and an animated map route, and it will apply the correct Remotion patterns for each part. ## Quick Start Use the remotion-best-practices skill to scaffold a new Remotion project and create an animated title composition with fade-in text.
