Overview
Remotion is a React-based framework for creating real MP4 videos programmatically. You write React components that read useCurrentFrame() and render what should appear at that instant. Remotion stitches every frame into a video file via headless Chromium + ffmpeg.
Key capabilities: frame-precise animation via interpolate/spring, timeline management via <Sequence>/
<TransitionSeries>
@remotion/captions
@remotion/media-utils
@remotion/renderer
Process
Scaffold — npx create-video@latest my-video to bootstrapDesign — Define color palette, typography, timing structure (acts/scenes)Build components — Create reusable animated components (cards, text, charts)Compose timeline — Use <Sequence> / <TransitionSeries> to orchestrate scenesPolish motion — Tune easing curves, spring configs, stagger delaysAdd audio — Background music, sound effects, voiceoverAdd captions — Transcribe or import SRT, display with @remotion/captionsRender draft — npx remotion render with fast settings (jpeg, high crf)Review — Watch the actual MP4, check timing and motion qualityRender final — Production settings (png or jpeg 80+, crf 18)

Root.tsx — Composition Registry import { Composition } from "remotion" ;
import { MyVideo } from "./MyVideo" ;
export const RemotionRoot : React .FC = () => (
<Composition
id ="MyVideo"
component ={MyVideo}
durationInFrames ={900} // 30 seconds at 30fps
fps ={30}
width ={1920}
height ={1080}
/>
Dynamic Metadata with calculateMetadata For data-driven duration/dimensions/props:
import { CalculateMetadataFunction } from "remotion" ;
const calculateMetadata : CalculateMetadataFunction <MyProps > = async ({
props, abortSignal,
}) => {
const data = await fetch (`https://api.example.com/video/${props.id} ` , {
signal : abortSignal,
}).then (r =>json ());
return {
durationInFrames : Math .ceil (data.duration * 30 ),
width : 1920 ,
height : 1080 ,
props : { ...props, videoUrl : data.url },
};
};
The Four Primitives
1. useCurrentFrame() — The Clock Returns the current frame number (0-indexed). Inside a <Sequence>, this is relative to the sequence start.
2. useVideoConfig() — The Constants const { fps, durationInFrames, width, height } = useVideoConfig ();
3. interpolate() — The Mapper (PREFERRED) Your primary animation tool. Prefer interpolate() over spring() unless physics-based motion is explicitly needed.
import { interpolate, Easing } from "remotion" ;
const opacity = interpolate (frame, [0 , 2 * fps], [0 , 1 ], {
extrapolateRight : "clamp" ,
extrapolateLeft : "clamp" ,
});
const enter = interpolate (frame, [0 , 45 ], [0 , 1 ], {
easing : Easing .bezier (0.16 , 1 , 0.3 , 1 ),
extrapolateLeft : "clamp" ,
extrapolateRight : "clamp" ,
});
Studio-Editable Animation (IMPORTANT) Keep interpolate() inline in the style prop. Use individual CSS transform properties, NOT transform strings:
style={{
scale : interpolate (frame, [0 , 100 ], [0 , 1 ]),
translate : interpolate (frame, [0 , 100 ], ["0px 0px" , "100px 100px" ]),
rotate : interpolate (frame, [0 , 100 ], ["20deg" , "90deg" ]),
opacity : interpolate (frame, [0 , 30 ], [0 , 1 ], { extrapolateRight : "clamp" }),
}}
const scale = interpolate (frame, [0 , 100 ], [0 , 1 ]);
style={{ transform : `scale(${scale} )` }}
Only use transform strings for skew(), perspective(), or order-sensitive multi-transform chains.
Copy-Paste Bézier Curves Curve cubic-bezier Use Crisp UI entrance (0.16, 1, 0.3, 1)Strong ease-out, no overshoot Editorial fade (0.45, 0, 0.55, 1)Balanced ease-in-out Snappy pop (0.34, 1.56, 0.64, 1)Overshoot, then settle Dramatic slow-in (0.7, 0, 0.84, 0)Long hold, fast release Smooth decel (0, 0, 0.2, 1)Gentle landing
4. spring() — The Physics Engine Use only when physics-based motion is explicitly needed. Always pass fps.
import { spring } from "remotion" ;
const scale = spring ({
frame,
fps,
config : {
damping : 20 ,
stiffness : 200 ,
mass : 0.5 ,
overshootClamping : true ,
},
});
Spring Config Presets Style damping stiffness mass overshootClamping Snappy (UI)20 200 0.5 true Smooth (text)15 100 1 true Bouncy (playful)8 180 1 false Gentle (bg)30 80 1.5 true Elastic (accent)5 150 0.8 false
Layout — Video-First Design Videos are watched differently than web pages are read. Design for quick understanding from the full frame.
Rules
One focal point per scene. One main text message, one supporting visual, one or two background accents.Safe area: Keep key text ≥80px from sides, ≥100px from top/bottom on 1080p.Use flex/grid/gap for readable content. Absolute positioning is for backgrounds, decorative shapes, particles.Solve crowding with time. Reveal elements sequentially instead of showing everything at once.Text sizing minimums (1080px-wide):
Main headline: 84px
Supporting text: 44px
Labels/callouts: 32px
Scale proportionally for other widths.
<AbsoluteFill>Base layer for everything. Later children render on top.
import { AbsoluteFill } from "remotion" ;
<AbsoluteFill style ={{
backgroundColor: "#FAFBFE ",
justifyContent: "center ",
alignItems: "center ",
}}>
<MyContent />
</AbsoluteFill >
<Sequence> — Timeline ManagementUse sequences to mount/unmount components at specific times. Never use if (frame > X) for lifecycle.
import { Sequence } from "remotion" ;
<AbsoluteFill >
<Sequence durationInFrames ={90} >
<Intro />
</Sequence >
<Sequence from ={90} durationInFrames ={630} >
<MainContent />
</Sequence >
<Sequence from ={720} durationInFrames ={180} >
<Outro />
</Sequence >
</AbsoluteFill >
useCurrentFrame() inside is relative to fromChildren unmounted after durationInFrames (performance win)
Default: wraps in <AbsoluteFill>. Use layout="none" for flex/grid children.
Using Frontend Skills in Video Context Remotion components are React — you can (and should) use frontend skills for styling, layout, and component design. But video has different constraints than web.
What transfers from web → video Web Skill How to use in Remotion tailwind-advanced Install via @remotion-dev/tailwind package. Use for rapid styling of cards, badges, layouts. frontend-design Typography hierarchy, spacing rhythm, visual hierarchy — all apply to video frames. shadcn-ui Use shadcn components (Card, Badge, Button) as visual building blocks in product demos and dashboard mockups. design-tokens Define brand colors, spacing, typography tokens once, use across all compositions. styled-components Works in Remotion. Good for dynamic styles driven by frame number.
What does NOT transfer Web Pattern Why it fails in video @media queries / responsive breakpointsVideo has fixed dimensions (1920×1080). No responsive design. CSS transitions / animations FORBIDDEN — they desync from the frame clock. Use interpolate().Hover / focus states No mouse in video. No interactive states. rem / em unitsUse px — there's no root font-size to scale against. Lazy loading / code splitting Remotion renders every frame synchronously. No lazy loading. Browser-specific hacks Remotion uses headless Chromium. No cross-browser concerns. SEO / accessibility Not applicable to video output.
Video-first frontend rules
Fixed canvas — Always px, never relative unitsInline styles for animation — Keep interpolate() calls in style prop for Studio editabilityIndividual transform properties — Use scale, translate, rotate (not transform string)Large text — Main headline ≥84px, supporting ≥44px, labels ≥32px at 1080pOne focal point per scene — Not a dense dashboard; a clear visual messageNo z-index wars — Stacking is controlled by JSX source order in <AbsoluteFill>
Example: shadcn Card in a promo video import { AbsoluteFill , useCurrentFrame, interpolate, Easing } from "remotion" ;
const FeatureCard : React .FC <{ title : string ; delay : number }> = ({ title, delay } ) => {
const frame = useCurrentFrame ();
const enter = interpolate (
Math .max (0 , frame - delay),
[0 , 20 ], [0 , 1 ],
{ easing : Easing .bezier (0.16 , 1 , 0.3 , 1 ), extrapolateRight : "clamp" }
);
return (
<div style ={{
opacity: enter ,
translate: `0px ${interpolate (enter , [0 , 1 ], [30 , 0 ])}px `,
background: "white ",
borderRadius: 12 ,
padding: 32 ,
boxShadow: "0 4px 24px rgba (0 ,0 ,0 ,0.06 )",

Audio Visualization (Podcast/Audiogram) Install: npx remotion add @remotion/media-utils
import { useWindowedAudioData, visualizeAudio } from "@remotion/media-utils" ;
import { staticFile, useCurrentFrame, useVideoConfig } from "remotion" ;
const { audioData, dataOffsetInSeconds } = useWindowedAudioData ({
src : staticFile ("podcast.wav" ),
frame, fps,
windowInSeconds : 30 ,
});
const frequencies = visualizeAudio ({
fps, frame, audioData,
numberOfSamples : 256 ,

dataOffsetInSeconds,
});
<div style ={{ display: "flex ", alignItems: "flex-end ", height: 200 }}>
{frequencies.map((v, i) => (
<div key ={i} style ={{
flex: 1 , height: `${v * 100 }%`,
backgroundColor: "#0b84f3 ", margin: "0 1px ",
}} />
))}
</div >
Voiceover (ElevenLabs TTS) Generate speech per scene, then use calculateMetadata to size the composition:
const response = await fetch (
`https://api.elevenlabs.io/v1/text-to-speech/${voiceId} ` ,
{
method : "POST" ,
headers : {
"xi-api-key" : process.env .ELEVENLABS_API_KEY !,
"Content-Type" : "application/json" ,
},
body : JSON .stringify ({
text : "Welcome to the show." ,
model_id : "eleven_multilingual_v2" ,
voice_settings : { stability : 0.5 , similarity_boost : 0.75 , style : 0.3 },
}),
},
);
const audioBuffer = Buffer .from (await response.arrayBuffer ());
writeFileSync (`public/voiceover/scene-01.mp3` , audioBuffer);
Use calculateMetadata + getAudioDuration to dynamically set duration from audio length.
Captions & Subtitles Install: npx remotion add @remotion/captions
import type { Caption } from "@remotion/captions" ;
type Caption = {
text : string ;
startMs : number ;
endMs : number ;
timestampMs : number | null ;
confidence : number | null ;
};
Transcribe: Use Whisper or ElevenLabs to generate captions from audioImport SRT: Parse .srt files into Caption[]Display: Use <CaptionRenderer> for word-by-word highlighting
Fonts
Google Fonts (Recommended) Never use CSS @import or <link> — Remotion blocks rendering until loadFont() completes.
import { loadFont } from "@remotion/google-fonts/Inter" ;
const { fontFamily } = loadFont ("normal" , {
weights : ["400" , "600" , "700" ],

});
<AbsoluteFill style ={{ fontFamily }}>
<h1 style ={{ fontWeight: 700 , fontSize: 84 }}> Hello</h1 >

Professional Motion Design Patterns
Pattern 1: SaaS Hero Video (Capitalise.ai style) Clean white background, dashboard mockups floating in with orchestrated timing.
<AbsoluteFill >
<Sequence from ={0} durationInFrames ={150} >
<BrandReveal /> {/* Logo + tagline fade in */}
</Sequence > <Sequence from ={150} durationInFrames ={900} >
<DashboardScene /> {/* Sidebar + floating cards */}
</Sequence > <Sequence from ={1050} durationInFrames ={300} >
<ClosingCTA /> {/* Fade to white, CTA */}
</Sequence > AbsoluteFill >
Pattern 2: Floating Card Entry const FloatingCard : React .FC <{
delay : number ;
direction : "left" | "right" | "up" ;
children : React .ReactNode ;
}> = ({ delay, direction, children } ) => {
const frame = useCurrentFrame ();
const { fps } = useVideoConfig ();
const enter = interpolate (
Math .max (0 , frame - delay),
[0 , 20 ], [0 , 1 ],
{ easing : Easing .bezier (0.16 , 1 , 0.3 , 1 ), extrapolateRight : "clamp" }
);
const offsets = { left : [-120 , 0 ], right : [120 , 0 ], up : [0 , -80 ] };
const [dx, dy] = offsets[direction];
return (
<div style ={{
opacity: enter ,
translate: `${interpolate (enter , [0 , 1 ], [dx , 0 ])}px ${interpolate (enter , [0 , 1 ], [dy , 0 ])}px `,
scale: interpolate (enter , [0 , 1 ], [0.95 , 1 ]),
}}>
{children}
</div >
Pattern 3: Staggered List Reveal {items.map ((item, i ) => {
const delay = i * 8 ;
const enter = interpolate (
Math .max (0 , frame - delay),
[0 , 20 ], [0 , 1 ],
{ easing : Easing .bezier (0.16 , 1 , 0.3 , 1 ), extrapolateRight : "clamp" }
);
return (
<div key ={i} style ={{
opacity: enter ,
translate: `0px ${interpolate (enter , [0 , 1 ], [30 , 0 ])}px `,
}}>
{item}
</div >
Pattern 4: Typewriter Effect const TypewriterText : React .FC <{ text : string ; cps ?: number ; startFrame ?: number }> = ({
text, cps = 30 , startFrame = 0 ,
} ) => {
const frame = useCurrentFrame ();
const { fps } = useVideoConfig ();
const elapsed = Math .max (0 , frame - startFrame);
const chars = Math .min (text.length , Math .floor (elapsed * (cps / fps)));
return (
<span >
{text.slice(0, chars)}
<span style ={{ opacity: frame % 16 < 8 ? 1 : 0 }}> |</span >
</span >
Pattern 5: Parallax Background const ParallaxScene : React .FC = () => {
const frame = useCurrentFrame ();
const { durationInFrames } = useVideoConfig ();
return (
<AbsoluteFill >
<AbsoluteFill style ={{ translate: `${interpolate (frame , [0 , durationInFrames ], [0 , -200 ])}px 0 ` }}>
{/* Background — sky, gradient */}
</AbsoluteFill >
<AbsoluteFill style ={{ translate: `${interpolate (frame , [0 , durationInFrames ], [0 , -400 ])}px 0 ` }}>
{/* Mid-ground — buildings */}
</AbsoluteFill >
<AbsoluteFill style ={{ translate: `${interpolate (frame , [0 , durationInFrames ], [0 , -600 ])}px 0 ` }}>
{/* Foreground — text, CTA */}
</AbsoluteFill >
</AbsoluteFill >
Pattern 6: Beat-Synced Pulse const BeatPulse : React .FC <{ bpm : number }> = ({ bpm } ) => {
const frame = useCurrentFrame ();
const { fps } = useVideoConfig ();
const framesPerBeat = (fps * 60 ) / bpm;
const beatPhase = (frame % framesPerBeat) / framesPerBeat;
const pulse = interpolate (beatPhase, [0 , 0.1 , 0.3 ], [1 , 1.05 , 1 ], { extrapolateRight : "clamp" });
return <div style ={{ scale: pulse }}> {/* Content */}</div >

Anti-Rationalization Table Rationalization Reality "CSS animations are simpler" CSS animations desync from the frame clock. Every pixel will be wrong on render. "I'll use transform: scale()" Not editable in Remotion Studio. Use individual scale, translate, rotate properties. "spring() looks better" Official guidance: prefer interpolate() unless physics is explicitly needed. "I'll hardcode frame numbers" Breaks when fps changes. Always use fps from useVideoConfig(). "Regular <img> is fine" Doesn't block render. Images flicker. Use Remotion's <Img>. "CSS @import for fonts" Render starts before fonts load. Use @remotion/google-fonts. "Small text looks clean" Video is watched at distance. Main headline ≥84px at 1080p. "Show everything at once" Crowded frames lose viewers. Solve crowding with time — reveal sequentially. "Good enough motion" Jarring timing and amateur easing are immediately visible. Polish the motion. "I don't need extrapolateRight: clamp" Values continue past range — elements fly off screen.
