Remotion

Overview

Remotion enables programmatic video creation using React components. Compositions define renderable videos with explicit width, height, fps, and duration. All animations must be driven by useCurrentFrame() -- CSS animations and Tailwind animation classes are forbidden as they cause rendering artifacts. Use this skill for Remotion compositions, animations, audio, captions, transitions, media handling, or rendering. Not intended for general React UI development.

Quick Reference

Pattern	API / Approach	Key Points
Basic animation	useCurrentFrame() + interpolate()	Always clamp with extrapolateRight: 'clamp'
Spring animation	spring({ frame, fps })	{ damping: 200 } for smooth, no-bounce motion
Composition	<Composition id, component, durationInFrames, fps, width, height>	Always set explicit dimensions
Dynamic metadata	calculateMetadata on <Composition>	Set duration, dimensions, props before render
Sequencing	<Sequence from, durationInFrames>	useCurrentFrame() returns local frame (starts at 0)
Series	<Series> with <Series.Sequence>	Sequential playback; negative offset for overlaps
Transitions	<TransitionSeries> with fade(), slide(), wipe()	Total duration = sum of scenes minus transition durations
Audio/Video	<Audio> / <Video> from @remotion/media	Use staticFile() for local assets
Captions	createTikTokStyleCaptions()	Token-level word highlighting via page.tokens
Images	<Img> from remotion	Never use native <img> or Next.js <Image>
GIFs	<AnimatedImage> from remotion	Synced with timeline; playbackRate for speed control
Fonts	@remotion/google-fonts or @remotion/fonts	Call loadFont() at top level; blocks rendering until ready
3D content	<ThreeCanvas> from @remotion/three	Must set width/height; useFrame() from R3F is forbidden
Text measurement	measureText(), fitText() from @remotion/layout-utils	Load fonts first; match properties for measurement and render
Parameters	Zod schema on <Composition schema>	Top-level must be z.object(); exact Zod version required (check Remotion docs)
Transparent video	--pixel-format=yuva420p --codec=vp9	WebM for browser; ProRes 4444 for editing software
Maps	Mapbox with useCurrentFrame()	Set interactive: false, fadeDuration: 0; render with --gl=angle --concurrency=1

Common Mistakes

Mistake	Correct Pattern
Using CSS animations or setTimeout	Use interpolate() and useCurrentFrame() for timeline-synced animations
Using native <img>, <video>, <audio> tags	Use <Img>, <Video>, <Audio> from Remotion for proper preloading
Hardcoding video duration	Use calculateMetadata to dynamically set duration from content
Not specifying width/height on compositions	Always define explicit dimensions to avoid rendering issues
Using useFrame() from React Three Fiber	Use useCurrentFrame() from Remotion inside <ThreeCanvas>
Forgetting premountFor on sequences	Always premount sequences to preload components before playback
Not clamping interpolate() output	Set extrapolateRight: 'clamp' to prevent values exceeding target range
Placing <Sequence> in <ThreeCanvas> without layout="none"	Set layout="none" on any <Sequence> inside <ThreeCanvas>

Delegation

• Discover available Remotion components and their props: Use Explore agent to search the codebase for composition definitions and asset usage
• Build a multi-scene video with transitions and audio: Use Task agent to compose sequences, transitions, and audio tracks step by step
• Plan a video generation pipeline with dynamic data: Use Plan agent to design the architecture for parametrized compositions and rendering workflow
