Example of converting clickbank video please

Hi. I have done youtube+ppd with small success in the past but have never managed to make a successful clickbank video. I'm fairly certain it was a problem with the videos themselves so I'm wondering if somebody could just show me an example video that they know converts. Any help would be great.

exactly what is the problem, be specific pls?

I don't think there is one answer that will be right. What are you trying to sell? What is your target audience? I run a successful multimedia studio, and would be happy to give you some tips.
