A background video can add motion, emotion, and context to your site when used correctly. It should support your message, not overpower it. Before adding one, prioritize performance, accessibility, and a clear fallback for small screens so visitors get the experience you intend.
Key considerations
- Purpose & length: Use video to reinforce a single idea — a short loop under 15 seconds works best for backgrounds; avoid long narrative clips.
- File size & formats: Compress aggressively and provide modern formats such as MP4 and WebM. Smaller files mean faster loads and fewer abandoned visits.
- Autoplay, mute & controls: If the video autoplays, keep it muted and looping, and give users a clear control to pause or disable motion.
- Mobile fallback: Offer a poster image or disable the background video on mobile to preserve bandwidth and battery life.
- Accessibility: Ensure important content is available as text, provide a short descriptive caption or transcript in the page content, and use overlays so text remains legible.
- Performance: Lazy load the video, serve responsive sizes, and deliver via CDN when possible to protect Core Web Vitals.
Implementation tips
- Optimize export settings and create a short, seamless loop.
- Host on a CDN or your server, use a poster image, and provide fallbacks for older browsers.
- Test on multiple devices and measure load times and perceived performance.
- Keep motion aligned with brand tone and avoid distracting visitors from calls to action.
