Having trouble importing videos to computer from Nikon camera?

I've taken some videos with my Nikon camera and I tried uploading them to my PC. They say they are uploading but I can never locate them on the computer after that and every time I plug my camera in, it tries to re-upload them. It never says there's an error when uploading them. What could be wrong? How can I get them uploaded? I need to get them on my computer and saved so I can get the space back on my card: P Thanks! I have a Nikon D3200

When I upload movies from my camera
they look like regular pictures until I click on them

Take control of your computer. It's the same process for pictures and videos.
