On desktops

On pageload ARVE Pro loads just a thumbnail image, title and play icon (all optional). The actual player is loaded when the thumbnail is clicked. The video will start to play as soon as the player loads.

On mobiles

Unfortunately mobile browsers prevent loading iframes with autoplaying videos. This is mitigated with the YouTube and Vimeo JavaScript APIs and does not affect HTML5 videos. But for other video hosts this means users may have to click twice to play.
