Native <video> in HTML is extremely good these days. Videos encoded with H264/AAC are universally playable and with HTTP chunk support you can serve the same video to all users.

However, browsers seem to request videos with preload=auto/metadata as soon as the page loads which is unnecessary. So I built this lazy-load solution that hides the src attribute (prevents loading) until an Intersection Observer callback.
