Create production-grade motion graphics and videos using Remotion (React). Use whenever the user wants branded video content, product demos, data-driven video generation, or motion graphics with audio sync, web fonts, TailwindCSS styling, or media embedding. Covers: marketing videos, product launches, data visualizations, social media content, personalized video at scale, explainer videos with voiceover, animated charts, 3D scenes via Three.js. Requires Node.js and Claude Code environment. Trigger on: "create a Remotion video", "React video", "motion graphics", "branded video", "product demo video", "remotion", "video with audio", "TailwindCSS video", "data-driven video generation", "personalized video at scale", "video with voiceover". For mathematical animations, algorithm visualizations, or headless container rendering, use concept-to-video (Manim) instead.

Remotion Video

Creates production-grade videos using Remotion — a React framework where video is code. Every frame is a React component. Animations use spring physics and frame-based interpolation.

Why Remotion

Remotion treats video as a React application. Each frame is a pure function of time — given frame N and total frames F, your component renders deterministically. This means:
  • Component composition: Nest scenes, reuse components, apply CSS.
  • Spring physics:
    spring()
    gives natural motion without hand-tweaking cubic beziers.
  • Asset pipeline: Import images, audio, video — the same way you import in React.
  • Iterative workflow: Edit code → hot-reload preview → render final. The
    .tsx
    file IS the editable intermediate.
  • Data-driven at scale: Render thousands of personalized videos by passing different props to the same composition.

Workflow

text
Scaffold → Compose → Preview → Iterate → Render
  1. Scaffold the project (once per video project)
  2. Interpret the user's concept — choose the right template and rule files
  3. Compose React components for each scene
  4. Preview in Remotion Studio (
    npm run dev
    )
  5. Iterate based on user feedback
  6. Render final video via
    scripts/render.sh

Step 0: Ensure Dependencies

Node.js 18+ is required. Check before scaffolding:
bash
node --version   # Must be >= 18.0.0
npm --version
If Node.js is not available, inform the user — Remotion cannot run without it.

Step 1: Scaffold the Project

Run
scripts/scaffold_project.sh
to create a new Remotion project. The script is idempotent — it detects an existing project and skips re-initialization.
bash
bash scripts/scaffold_project.sh my-video-project
cd my-video-project
npm run dev   # Opens Remotion Studio at localhost:3000

Step 2: Interpret the Concept

Determine the best approach. Read the relevant rule file for detailed patterns.
Content typeRule fileTemplate
Explainer / educationalfundamentals.mdexplainer.tsx
Product demo / marketinganimations.mdproduct-demo.tsx
Data visualization / animated chartcharts.mddata-viz.tsx

Social media clip (short, looping)animations.mdproduct-demo.tsx
3D scene / abstract motion graphicsthree-d.md(custom)
Personalized / batch generationdata-driven.mdany
Video with embedded mediamedia.mdany

Step 3: Compose the Components

Core rules for writing Remotion components:
  • One composition per video:
    registerRoot
    points to one root composition.
  • Sequences for timing: Use
    <Sequence from={30} durationInFrames={60}>
    to place scenes at specific frames.
  • AbsoluteFill for layering: Use
    <AbsoluteFill>
    as the base for any full-screen element.
  • Frame-based math only: Derive all animation state from
    useCurrentFrame()
    . Never use
    Date.now()
    or
    setTimeout
    .
  • Spring over easing: Prefer
    spring({ frame, fps })
    for natural motion.
  • Props for everything variable: Hardcoded values → props. This enables data-driven rendering.

Component structure pattern

tsx
import {
  useCurrentFrame,
  useVideoConfig,
  interpolate,
  spring,
  AbsoluteFill,
  Sequence,
} from "remotion";

type MySceneProps = {
  title: string;
  accentColor: string;
};

export const MyScene: React.FC<MySceneProps> = ({ title, accentColor }) => {
  const frame = useCurrentFrame();
  const { fps, durationInFrames } = useVideoConfig();

  const opacity = interpolate(frame, [0, 30], [0, 1], {
    extrapolateRight: "clamp",
  });
  const scale = spring({ frame, fps, config: { damping: 12, stiffness: 100 } });

  return (
    <AbsoluteFill style={{ backgroundColor: "#0a0a0a" }}>
      <div
        style={{ opacity, transform: `scale(${scale})`, color: accentColor }}
      >
        {title}
      </div>
    </AbsoluteFill>
  );
};

Step 4: Preview

Remotion Studio provides hot-reload preview. Start it with:
bash
npm run dev
Studio opens at
http://localhost:3000
. The timeline scrubber lets you inspect any frame.
Use
<Still>
component for frame-accurate screenshots during iteration.

Step 5: Iterate

RequestAction
"Slower/faster"Adjust
durationInFrames
on
<Sequence>
or change FPS
"Different color"Update props passed to composition
"Add a section"Add new
<Sequence>
block with incremented
from
offset
"Change font"Load via
@remotion/google-fonts
, apply as CSS
fontFamily
"Add background music"Add
<Audio src={staticFile('audio.mp3')} />
to root composition
"Make it loop"Set
durationInFrames
and design matching first/last frame state
"Add captions"See subtitles.md for SRT parsing and word-level timing

Step 6: Render

Use
scripts/render.sh
to render the final video:
bash
bash scripts/render.sh --composition MyComposition --quality final --format mp4

Limitations

  • Node.js required — Remotion is a Node.js framework. Cannot run in Python-only or headless container environments.
  • Chromium dependency — Remotion renders via Chromium. The
    npx remotion render
    command downloads it automatically, but it requires ~300MB disk space.
  • No server-side Lambda in v1 — Cloud rendering via
    @remotion/lambda
    is deferred to a future skill version. Local rendering only.
  • Large renders are slow — A 60-second 1080p video at 30fps = 1800 frames rendered through Chromium. Plan for 10-30 minutes on a typical laptop.
  • GIF size — GIFs at full resolution are large. Limit to 480p and <10 seconds for embeddable GIFs.
  • Audio in preview — Remotion Studio supports audio playback in preview. Rendered audio requires ffmpeg.

Design Principles

  • Frame-based thinking: Every visual state is a function of the current frame number. No timers, no intervals.
  • Composition-first: Split video into logical
    <Sequence>
    blocks. Each scene is its own component.
  • Spring over easing:
    spring()
    gives physically accurate motion. Only use
    interpolate
    with easing when spring doesn't fit.
  • Props for content: Never hardcode strings, colors, or data inside components. Pass via props to enable reuse.
  • Type everything: All composition props have TypeScript types enforced via
    z.infer<typeof schema>
    (Zod) or explicit interfaces.

Cross-Reference

For mathematical animations, algorithm visualizations, or when Node.js is unavailable, use
concept-to-video
(Manim/Python) instead. Manim runs in any Python environment and excels at geometric proofs, equation animations, and LaTeX rendering.
