Video

jampack optimize videos below the fold.

Autoplay videos

Videos below the fold with attribute autoplay are lazy loaded using JavaScript.

Click-to-play videos

Videos without autoplay and with a poster get a preload="none" attribute to postpone the loading of the video until user request.

As of today, jampack doesn’t automatically create posters for video. It’s a TODO.
