Is there a way to render a short loop into a longer video?

Hi,
I have a 6 second video clip I need to render as a 3 minute loop.
I know I can copy and paste the clip to make a 3 minute long video. But is there a way to simply render the 6 second video clip to a specific length using the transport's loop function?
Thanks,
Chris
