Autoplay video on scroll into view

Hi there,

I think I have a simple question, but it seems like I can’t find the right answer anywhere.

I wanna autoplay a video that I host from Dropbox when it is scrolled into view.

I can make it autoplay in the preview but not on scroll into view. On the published site the video doesn’t even play at all.
