My camera won't focus?

I got the Nikon Coolpix L610 because it not only takes good pictures but the records at 1080p, now i'm having a problem because while I was recording a makeup tutorial video for youtube, the camera would constantly blur out and then blur back in and focus and then it would blur out for sometimes a minute. Any advice? Please help.
