I would like to play video thru the lightbox (prefer not to use youtube or vimeo) and have accomplished this by (1) uploading video to the Media Library, (2) copy and paste media link to "edit Post" or Portfolio items page and inserting link in "Use Video instead of Featured Images" options. Video plays back perfectly.
However, the first frame of video image does not appear on the post or portfolio items? It shows the URL link? Is there an option to show an image or the first frame of video?
