This plugin allows you to embed an ogg, mp4 file or YouTube or Vimeo video into your page. As the user of your website scrolls down the page to read the rest of your article and they can’t see the video any more, the video will automatically move and stick to one of the corners of the window so they can watch the video and read the page at the same time. This creates an effect like the one that can be seen on the videos of CNN, Daily Mail, and the new material design version of YouTube.
This is very useful if you have lots of articles or pages which have accompanying videos, which the user may want to watch while also reading the rest of the article or page.
The plugin will insert a video into a post or page using a shortcode. 
The plugin also adds a button to the visual editor so that you can easily intergrate the floating video into all of your pages.

Floating Video

Display a video that, when scrolled out of view, moves to the corner of the screen so that the user can continue watching it while reading a post.
