I was wondering when somebody would get to Cyberlink PowerDirector, I have never heard of any of the others, but use Cyberlink PowerDirector all the time......works great for me, even if I haven't mastered all the things it can do....I've been using Cyberlink PowerDirector for years. It can be simple for beginners but also has plenty of depth as you gain experience. I really like its speed, even when handling 4K video.
