While all are good suggestions, I think Larry is "on the mark". I design curricula and multimedia products. I generally work with teams of specialized professionals.
Every video professional I have ever worked with, for the last 10 years, prefered Adobe Premiere when working with raw video. It is also simple enough that I picked up the basics in a few hours. PREMIERE is not cheap, but worth every penny.
As well as the others suggested, you might also look into Adobe ELEMENT. It offers a scaled-suite version of Adobe's media tools.
