Remotion Animation Rules

Overview

This skill enables Claude to create technically correct animations in Remotion by following Remotion-native rendering and animation principles.

Unlike traditional frontend animation workflows, Remotion relies entirely on deterministic frame-based rendering instead of browser-driven animation systems.

This workflow focuses on:

  • proper use of useCurrentFrame()
  • spring-driven motion systems
  • deterministic rendering
  • layout stability
  • frame-based timing
  • avoiding unsupported animation patterns

The goal is to ensure animations remain smooth, stable, render-safe, and consistent across all frames.


Setup

Before starting:

  1. Install Node.js: https://nodejs.org

  2. Verify installation:

node -v
npm -v
  1. Create a Remotion project:
npm init video
  1. Start development server:
npm run dev
  1. Open the project in VS Code.

Recommended tools:

  • VS Code
  • Remotion Preview
  • React knowledge
  • Prettier extension

Inputs Required
  • Animation concept
  • Video duration
  • Scene structure
  • Assets:
    • text
    • subtitles
    • images
    • audio

Optional:

  • Branding guidelines
  • Existing motion references
  • Storyboards

When to Use This Skill

Use this skill when:

  • creating Remotion animations
  • building subtitle systems
  • implementing transitions
  • designing motion graphics
  • creating reusable animation logic
  • debugging unstable animations
  • optimizing rendering consistency

When NOT to Use

Do NOT use this skill for:

  • CSS-based animation systems
  • browser-driven transition workflows
  • static design tasks
  • traditional video editors without React workflows

Example Use Case

Create animated subtitles for a startup launch video.

Claude should:

  1. Use useCurrentFrame() for all animation timing
  2. Apply spring physics for subtitle motion
  3. Avoid CSS transitions entirely
  4. Synchronize subtitle appearance frame-by-frame
  5. Maintain stable layout dimensions
  6. Ensure rendering remains deterministic across exports

Final output should:

  • render consistently
  • avoid timing glitches
  • maintain smooth motion
  • prevent layout instability
  • remain export-safe

Core Remotion Principles

1. Everything Should Be Frame-Based

In Remotion, animation timing should always derive from the current frame.

Preferred APIs:

  • useCurrentFrame()
  • interpolate()
  • spring()

Example:

const frame = useCurrentFrame();

This ensures:

  • deterministic rendering
  • precise synchronization
  • export consistency

Avoid:

  • setTimeout
  • browser timing systems
  • uncontrolled animations

2. Use Spring Physics for Motion

Motion should use spring-driven systems whenever possible.

Preferred approach:

spring({
  frame,
  fps,
  config: {
    damping: 200,
  },
});

Spring systems provide:

  • smoother easing
  • predictable movement
  • natural motion behavior

Best use cases:

  • scaling
  • fade-ins
  • subtitle reveals
  • slide animations
  • transitions

Avoid:

  • CSS easing transitions
  • uncontrolled interpolation
  • browser-driven animation timing

3. Avoid CSS Transitions Entirely

CSS transitions are not reliable in Remotion workflows.

Incorrect approach:

transition: all 0.3s ease;

Problems caused by CSS transitions:

  • inconsistent rendering
  • export mismatches
  • timing instability
  • browser-dependent behavior

Preferred approach:

  • calculate motion directly from frame values
  • use interpolation or springs

4. Control Layout Stability

A common Remotion issue is layout shifting during animation.

Example issue:

  • text jumps while typing animation plays

Recommended fix:

  • render invisible full text in background
  • overlay animated text separately
  • preserve stable layout dimensions

Claude should proactively prevent:

  • text reflow
  • resizing during animation
  • unstable positioning
  • dynamic layout shifts

Stable layouts improve:

  • render consistency
  • subtitle readability
  • animation smoothness

5. Keep Animations Deterministic

Animations should behave identically on every render.

Motion systems should:

  • use predictable timing
  • avoid randomness
  • remain frame-controlled
  • synchronize accurately with audio

Deterministic rendering improves:

  • export reliability
  • debugging
  • synchronization
  • production stability

Workflow

1. Define Animation Structure

Start by identifying:

  • video duration
  • scene breakdown
  • subtitle timing
  • transition requirements

Organize the animation into reusable scene components.

Example structure:

scenes/
  Intro.tsx
  Features.tsx
  CTA.tsx

2. Implement Frame Logic

Use useCurrentFrame() inside scenes.

Example:

const frame = useCurrentFrame();

All animation state should derive from frame progression.


3. Add Motion Systems

Use:

  • spring()
  • interpolate()

Preferred animation behaviors:

  • smooth movement
  • controlled scaling
  • timed transitions
  • synchronized subtitles

Avoid:

  • CSS animation systems
  • browser-controlled timing
  • uncontrolled easing

4. Validate Layout Stability

Check for:

  • text jumping
  • resizing
  • subtitle shifts
  • unstable positioning

Fix instability before rendering.


5. Render Final Video

Before export validate:

  • timing consistency
  • motion smoothness
  • subtitle synchronization
  • layout stability

Render output:

npm run build

or:

npx remotion render

Preferred export:

  • MP4
  • platform-optimized settings

Output Expectations

The final output should include:

  • smooth frame-based animation
  • deterministic rendering
  • stable layouts
  • synchronized subtitles
  • production-ready video export

The workflow itself should remain:

  • reusable
  • modular
  • maintainable
  • render-safe

Execution Strategy (for AI agents)

The agent should:

  1. Use Remotion-native animation systems only
  2. Control all motion frame-by-frame
  3. Avoid unsupported browser animation patterns
  4. Maintain deterministic rendering behavior
  5. Detect and prevent layout instability proactively
  6. Validate animation consistency before export

The workflow should optimize for:

  • rendering consistency
  • timing precision
  • layout stability
  • smooth motion
  • export reliability

Best Practices
  • Use useCurrentFrame() for all timing
  • Prefer spring animations over manual easing
  • Keep scenes modular
  • Validate animations frame-by-frame
  • Avoid layout-dependent motion
  • Keep subtitle systems stable
  • Reuse motion patterns across scenes

Notes
  • useCurrentFrame() is central to Remotion workflows
  • CSS transitions should never be relied on
  • Spring systems produce more natural motion
  • Stable layouts significantly improve render quality
  • Deterministic rendering is critical for professional video workflows
