Can you import videos to video files and photos to photo files simultaneously?

when importing from an iphone, all the videos and photos are getting put in the photos folder of PhotoGallery.  I look under File Options to change importing settings but it does not have a way to send photos to photos and videos to videos when importing from a camcorder or iphone - they all get lumped together into one folder.  i don't understand why they get lumped together or how a person is meant to organize them like that.  I am used to using iPhoto and iMovie and the two programs handled their own file types so I'm having a hard time understanding how PhotoGallery and MovieMaker are meant to work together.
