I am using windows 8.1
1) If you want the music soundtrack to loop, click the "loop soundtrack" option at the bottom of the music selection menu.
2) If you just want the video to loop during playback, then you will have to use a video player with that capability.
This article explains how to loop video in Quicktime player: http://tl2014.files.wordpress.com/2013/01/looping-a-video-in-quicktime.pdf
If you want something else, then you will probably have to describe what you want more clearly.

I have downloaded quicktime player in order to play my video continuously... however it says 'quicktime player cannot open files of this type'. What else can I open it with and have the continuous loop?
