I have been looking for a non plugin solution where a user can upload a video, say, something from a site like http://www.coverr.co/.
When the user adds the video via the featured image link in the post/page editor, a static image will be generated and used as the featured image, but when the post is viewed, the title of the post is displayed on top of the actual video being played.
Hope that made sense. So far I haven't found anything. Ideas?
