Why does my Nikon 1 J1 camera stop recording automatically?

I have a SanDisk Ultra card with 32 GB. I have no pictures or videos on my memory card. It stops recording automatically and it says "processing video" or something like that when it stops. It is so irritating and I just bought it! I loved the camera until this problem came up. Please tell me that there's something I can do to fix this!

It also says that I can record for 20 minutes, but it stops after 1 minute or something like that!

Processing video means it can't load data onto your SD card fast enough and the solid state buffer on the camera has filled. Where did you get your SD card? There are a lot of "fake" cards being sold in asia and on eBay that are just cheap class 2 cards that have been rebranded to look like famous name high speed cards.
