Hello,
not that long ago I wanted to make a youtube video, not wanting to spend any money I decided to find a free editing software. The best software I found was HitFilm 4 Express, it is a bit harder to use than professional programs, it's not as intuitive and its composite shots are annoying, however compared to others it's really useful. There is basically everything you need for basic editing + some effects, so it's pretty cool. If you don't want to spend hundreds of dollars on software, it's your best choice.
