My money is on Cyberlink Video Director. Great program with tons of adjustments and special effects. Along with Video Director adding Color Director and Audio Director, you can do most anything you want. There is a trial period for all three of these programs at the Cyberlink website. Lots on You Tube, and Cyberlink has many, many tutorials for us who need visual for training! Check it out.
I don't think you can beat Power Director for the money and the features. Also, the addition of Color Director and especially Audio Director gives added control over your editing.
