As part of our effort to provide rich and varied content, we've been incorporating more video on our site. The goal is to ensure you are able to view video without having to leave the Web page you are on - whether it is launching a new browser window or launching an external media player. But the positioning/placement of the video directly impacts the scale of the video. For example, if we are placing a video in the main content well of a page, embedding the video achieves our end goal; but if we need to place a video in less forgiving real estate like the right channel of a page, it renders the video unviewable and utlimately, ineffective as the video interface becomes much too small deeming the picture undecipherable and textual content unreadable.
So, our solution around such spatially challenging cases has been to provide a graphical promotion of the video which onclick launches an overlay on the page with a larger version of the video embedded in the overlay so users can clearly view the video. This way, users are not taken away from the originating Web page. And, once they are done watching the video, they can close the overlay and return to their regular browsing.
