Hi, Christopher: please see the first three grids on the following page: http://kypipe.com/draft-2018-release-video/.
There are other attempts on this page which are not grid-based that I just tried to play as an embedded video using HTML code. These have a “play” button but won’t autoplay either. If there is no way to autoplay a video within an essential grid, perhaps there is a workaround using one of these methods.
When I say autoplay when a page is opened, what I mean is when someone links to this page and it opens for the first time, I want the video to start playing on its own. See the last three animated GIFs on the page – they autoplay immediately and continuously loop, that’s what I’m looking to duplicate. Unfortunately those last three animated GIFs are displaying video files that are hosted within the WordPress Media Library, and I’d rather not load the Media Library up with too much data.
