Is there any step-by-step guide to make a loop of an existing video? I am newbie to video editing and I am having a hard time understanding the editor. I just want to make a loop of a three second video for a turntable animation.
You can either use Shift D to duplicate the strip or use this addon:

I could not get it to work though.
