Background video best practice
Keep loops short (6–15 seconds), scale to the displayed size, and cap frame rate at 24–30 fps. Dark or low-contrast footage compresses best and keeps overlaid text readable.
Use <video autoplay loop muted playsinline> with a poster image, and consider a prefers-reduced-motion media query to pause it for users who ask for less motion.
Frequently asked questions
Why is the audio removed?
Background videos must be muted to autoplay, so an audio track is just wasted bytes.
How big should a background video be?
Aim for under 2–3 MB for a hero loop; smaller is better on mobile.
Can a background video be transparent?
Yes — use transparent WebM, which composites over your page design.
