On the other hand I could develop a much more longer video...for example if I were to review a, let's say, clickbank product I could explain what the product is all about, benefits, who is it for, bonuses, testimonials,...etc.
I have plenty of experience with presentations and I know how to do it properly on powerpoint along with camtasia...(bullets, images, short sentences, etc.)
But it all comes down to experience which regarding YouTube video, I lack...
What would be your experience with video duration? what would you say is the optimal time for a product review (clickbank/amazon)?
