Pandora Hearts- God Is A Girl ||Alice&Will of Abyss||

I am back!!! Can somebody help me get a new video editing software that is free (that you can download for free with no trials) and not hard to figure out? I have Mkv clips that I want to use, but Windows Live Movie Maker is too laggy and sometimes freezes. Also thank you to all my subscribers :3 Anime- Pandora Hearts Characters: Alice and Will of Abyss Song: God is a Girl by Groove Coverage
