Youtube video editing? (Beauty channels)?

Okay so soon I will start making beauty videos like OOTD's, room tours, hauls, etc. What type of camera should I use? I have a nikon camera & my iphone 4. I also really need help in what type of video editing software I should use to edit my videos with? I need a free software that's easy to use!

Windows Movie Maker.

Good luck with a beauty channel, there's already alot of them out there and new ones get no success.

Thats a perfect camera (nikon) and for editing software, i prefer final cut pro, it has everything and its so easy to use, macup101 uses it and her videos are perfect
