I would really like to know the softwares behind these great videos I see in Nigeria.  Our guys are really been creative.  For example like Dbanj's Why me, I really would like to know the softwares that can do similar stuff.  And also Olorioko's Video.

I would like anyone who really have an idea bout these stuff that's willing to share should share with me and i know that there re other people who might be interested in knowing this also.  Hope to be back soon.

it is very simple software they used in those video i.e adobe premiere pro 2.0 & adobe after effects 7.0
