Responsive Video Demo Page

This demo page shows how to implement responsive videos with proper poster images that adapt to different screen sizes.

By using Shopify's preview_image feature, we create a responsive picture element that serves as an adaptive poster, ensuring users see crisp, device-optimized visuals while videos load.

Video preview

Key features of this implementation:

  • Responsive poster images that automatically match your video content across all screen sizes
  • Zero extra uploads required - uses Shopify's auto-generated preview_image from your video's first frame
  • Improved Core Web Vitals - poster images load faster than videos, reducing LCP times significantly
  • Better user experience - eliminates blank rectangles and stretched images during video loading
  • Mobile-optimized - serves portrait posters for mobile videos and landscape posters for desktop
