Remotion Video
Remotion is a framework for creating videos programmatically using React. Instead
of timeline-based editors, you write compositions as React components where every
frame is a function of the current frame number. This gives you the full power of
TypeScript, npm packages, and component-based architecture for building videos -
from animated explainers and social media clips to data-driven visualizations and
personalized video at scale.
This skill covers project setup, composition structure, frame-based animations
with interpolate and spring, scene sequencing, asset management, audio
integration, parametrized videos with Zod schemas, and rendering to MP4/WebM
via CLI or programmatic APIs.
When to use this skill
Trigger this skill when the user:
Wants to create a video programmatically using React/TypeScript
Asks about Remotion compositions, useCurrentFrame, or useVideoConfig
Needs to animate text, elements, or transitions between scenes
Wants to render a video to MP4, WebM, or GIF from code
Asks about spring animations, interpolate, or frame-based timing
Needs to set up a new Remotion project from scratch
Wants to add audio, images, or fonts to a Remotion video
Asks about parametrized/data-driven video generation
Needs to configure Remotion Studio for previewing compositions
Do NOT trigger this skill for:
General React questions unrelated to video creation - use React skills
Video editing with traditional timeline tools (Premiere, DaVinci, FFmpeg CLI)
CSS animations for web pages - use animation/motion-design skills
Video playback or streaming in web apps - use media player skills
Key principles
Every frame is a pure function - A Remotion component receives the current
frame via useCurrentFrame() and must render deterministically for that frame.
No side effects, no randomness without seeds, no reliance on wall-clock time.
The same frame number must always produce the same visual output.
Compositions are the unit of video - Each <Composition> defines a video
with explicit dimensions (width, height), frame rate (fps), and duration
(durationInFrames). Think of compositions as "pages" in your project - one
per video variant or scene that can be rendered independently.
Interpolate for everything - The interpolate() function maps frame
numbers to any numeric value (opacity, position, scale, color channels).
Combined with , it is the workhorse for all
animations. Use when you need physics-based easing.
extrapolateRight: 'clamp'
spring()
Sequence for time offsets - Use <Sequence from={frame}> to delay when
children start appearing, and <Series> to play children one after another.
Never use setTimeout or manual frame math for sequencing - the declarative
primitives handle it correctly across preview and render.
Assets are static, data is dynamic - Put images, fonts, and audio files
in the public/ folder and reference them with staticFile(). For dynamic
data (API responses, database records), use delayRender() /
continueRender() to pause rendering until the data is loaded.
Core concepts
Composition structure
Every Remotion project has a root file that registers compositions:
For programmatic rendering, see references/rendering-guide.md.
Anti-patterns / common mistakes
Mistake
Why it is wrong
What to do instead
Using Math.random() without a seed
Produces different output per frame during render
Use a deterministic seed or random() from Remotion
Using setTimeout / setInterval
Breaks frame-based rendering - timers do not advance per frame
Use useCurrentFrame() and frame math for all timing
Missing extrapolateRight: 'clamp'
Values overshoot beyond the target range on later frames
Always add { extrapolateRight: 'clamp' } to interpolate()
Hardcoding fps in frame calculations
Breaks when composition fps changes
Use useVideoConfig().fps to derive timing
Using <Video> for rendered output
Slower rendering performance due to seeking overhead
Use <OffthreadVideo> for better render performance
Forgetting delayRender() for async data
Renders before data loads, showing empty/broken frames
Call delayRender() immediately, continueRender() when ready
Inline styles with non-deterministic values
Flickers or inconsistency between preview and render
Derive all style values from the frame number only
Giant single composition
Hard to maintain and impossible to render scenes independently
Split into multiple compositions or use Series for scenes
Gotchas
extrapolateRight default is 'extend' - If you write interpolate(frame, [0, 30], [0, 1]) without clamping, the value will keep increasing beyond 1 after frame 30 (e.g., frame 60 gives opacity 2). Always pass { extrapolateRight: 'clamp' } unless you intentionally want extrapolation.
spring() starts from frame 0 of its context - When using spring() inside a <Sequence from={60}>, the frame passed to spring resets to 0 at frame 60 of the parent. If you pass the parent's raw frame, the animation will already be complete. Use useCurrentFrame() inside the Sequence child, not a frame from the parent.
staticFile() paths are relative to public/ - Calling staticFile('images/logo.png') looks for public/images/logo.png. Using absolute paths or paths outside public/ will fail silently in preview and error during render. Ensure all assets are in the public/ directory.
delayRender has a 30-second timeout - If your async operation (API call, font load) takes longer than 30 seconds, the render will abort. Increase the timeout with delayRender('Loading data', { timeoutInMilliseconds: 60000 }) for slow operations.
Composition dimensions must be even numbers - Video codecs (H.264, VP8) require even width and height. Remotion will throw an error if you use odd dimensions like 1921x1081. Always use even pixel values (1920x1080, 1280x720, etc.).
References
For detailed patterns on specific Remotion sub-domains, read the relevant file
from the references/ folder:
references/animation-patterns.md - advanced animation techniques including
staggered cascades, parallax effects, morph transitions, easing curves, and
complex multi-property animations
references/project-structure.md - project organization, parametrized videos
with Zod schemas, reusable component patterns, shared styles, and multi-
composition architecture
Only load a references file if the current task requires it - they are
long and will consume context.
