What video editor do you use?

 What video do you use for your tech videos? i am recently been getting into videos for my lets play games
and im looking for a good video editor. what do you recommend as a new user?

on the sidenote:
i have been using AE CS6 for a few days now but im having problems with it (video becomes off sync even tho original video isnt how?!1)

Logan uses Premiere Pro and After Effects. CS6 I think... might be CC tho

so how do i fix that?
do i have to lower the frame rate?
because when i play on vlc it works fine however when it hits in AE it starts to sync off and it very frusterating
