how to export videos from ipad to pc

i have tried everything and it's driving me absolutely mad!

I filmed a video with ipad camera, itunes doesn't see videos, the icloud doesn't upload videos, dropbox app won't work, they only upload to youtube in highly bad quality, too big to email and when i try to import photos and video on PC the import starts, the photos upload and when it reaches the videos it says it is not working...

HOW DO I EXPORT TO PC! someone please help...
