Video Content Accessibility

This Skill provides Claude Code with specific guidance on how it should handle accessibility in Remotion video compositions.

When to use this skill:

Designing video composition layouts and color schemes
Choosing text sizes and font weights for readability
Setting animation timing and transition durations
Using emojis or visual indicators in video content
Ensuring information hierarchy through visual design
Testing color contrast in theme.ts color choices

Instructions

Color Contrast: Maintain high contrast ratios (4.5:1 minimum) for text on backgrounds; test with various backgrounds
Readable Typography: Use large, clear fonts; minimum 48px for body text in 1080x1920 format
Text Alternatives: Ensure all information conveyed visually has text equivalents (e.g., star ratings + numeric score)
Animation Timing: Provide sufficient time for text to be read; minimum 3 seconds for short text
Emoji Accessibility: Use Noto Color Emoji font for consistent emoji rendering; always pair with text labels
Motion Sensitivity: Avoid jarring transitions; use smooth easing functions from src/lib/animations.ts
Information Hierarchy: Use size, color, and position to create clear visual hierarchy

Examples:

// Good: High contrast, large text, sufficient timing, text + visual
import { theme } from '@/lib/theme';

export const BookRating: React.FC<{ rating: number }> = ({ rating }) => (
  <div style={{
    backgroundColor: theme.colors.background, // Dark
    color: theme.colors.text, // Light - high contrast
    fontSize: 64, // Large and readable
    padding: 40,
  }}>
    <div>⭐ {rating.toFixed(1)}</div> {/* Emoji + numeric */}
  </div>
);

// Bad: Low contrast, small text, emoji only
<div style={{ color: '#666', fontSize: 24 }}>
  ⭐⭐⭐⭐
</div>
