Power Director 9.
Got it from a torrenting site years ago and still love and use it till this day. I've played around with other programs, like Abobe After Effects but it took me 5 years just to learn photoshop and AAE seemed even harder to learn.
Power Director is easy as hell to use. Drag and drop. You can add cool fxs super quick. You're not paralyzed with thousands of confusion options and it helps you focus more on the message, the script and the marketing rather than a bunch of useless hollywood fx that wind up killing conversions a lot of the time.
That's 1 issue I see with video marketers. It's ok to have a fancy intro / outro but you don't need all these crazy over lays and they are distracting.
Just by doing good editing and having access to all the most basic fxs you'd be suprised how good you can make your videos.
