Is it possible to create a continuously looping video?
I make similar videos for our corporate reception, interstate and overseas offices, events, conferences and presentations etc. The answer is to look outside the video file itself and focus on the application that is playing the file - you want the application to loop the video file playback.

An alternative approach that works on some devices is to embed the single instance of the video file in a PDF and set the playback preferences of the PDF viewer to loop.
