A specific case of the Link to video action is the video linked to itself. This way, you can create a reproduction loop, meaning, a video being reproduced in a loop indefinitely. To that end, simply choose the Link to video option and on the Next video drop-down menu displayed immediately after, select the same origin video.
This can be a helpful choice when a variety of options are offered on screen, the user has to choose one and for creativity purposes, we do not want the video background to be static. The time the user takes to decide on the option to choose, the video background is reproduced in an endless loop.
