Remotion — Toolkit Extensions

Core Remotion knowledge lives in .claude/skills/remotion-official/ (synced from the official remotion-dev/skills repo). This file covers toolkit-specific patterns only.

Shared Components

Reusable video components in lib/components/. Import in templates via:

import { AnimatedBackground, SlideTransition, Label } from '../../../../lib/components';

Custom Transitions

The toolkit includes a transitions library at lib/transitions/ for scene-to-scene effects beyond the official @remotion/transitions package.

Using TransitionSeries

import { TransitionSeries, linearTiming } from '@remotion/transitions';
// Import custom transitions from lib (adjust path based on your project location)
import { glitch, lightLeak, clockWipe, checkerboard } from '../../../../lib/transitions';
// Or import from @remotion/transitions for official ones
import { slide, fade } from '@remotion/transitions/slide';

<TransitionSeries>
  <TransitionSeries.Sequence durationInFrames={90}>
    <TitleSlide />
  </TransitionSeries.Sequence>
  <TransitionSeries.Transition
    presentation={glitch({ intensity: 0.8 })}
    timing={linearTiming({ durationInFrames: 30 })}
  />
  <TransitionSeries.Sequence durationInFrames={120}>
    <ContentSlide />
  </TransitionSeries.Sequence>
</TransitionSeries>

Available Custom Transitions

Checkerboard patterns: sequential, random, diagonal, alternating, spiral, rows, columns, center-out, corners-in

Transition Examples

// Tech/cyberpunk feel
glitch({ intensity: 0.8, slices: 8, rgbShift: true })

// Warm celebration
lightLeak({ temperature: 'warm', direction: 'right' })

// High energy zoom
zoomBlur({ direction: 'in', blurAmount: 20 })

// Chromatic aberration
rgbSplit({ direction: 'diagonal', displacement: 30 })

// Clock sweep reveal
clockWipe({ direction: 'clockwise', startAngle: 0 })

// Retro pixelation
pixelate({ maxBlockSize: 50, glitchArtifacts: true })

// Checkerboard patterns
checkerboard({ pattern: 'diagonal', gridSize: 8 })
checkerboard({ pattern: 'spiral', gridSize: 10 })
checkerboard({ pattern: 'center-out', squareAnimation: 'scale' })

Transition Duration Guidelines

Preview Transitions

Run the showcase gallery to see all transitions:

cd showcase/transitions && npm run studio

Toolkit Best Practices

1. Frame-based animations only — Avoid CSS transitions/animations; they cause flickering during render
2. Use fps from useVideoConfig() — Make animations frame-rate independent
3. Clamp interpolations — Use extrapolateRight: 'clamp' to prevent runaway values
4. Use OffthreadVideo — Better performance than <Video> for complex compositions
5. delayRender for async — Always block rendering until data is ready
6. staticFile for assets — Reference files from public/ folder correctly
7. All projects use 30fps — Timing: frames = seconds × 30
8. playbackRate must be constant — For variable/extreme speeds, pre-process with FFmpeg

Project Timing Conventions

Pacing: ~150 words/minute for voiceover. Voiceover drives timing.

Advanced API

For detailed API documentation on all hooks, components, renderer, Lambda, and Player APIs, see reference.md.
