what camera &techniques to make kickstarter type video(documentary feel)

[fabbulk]

Hello Guys ,

I am a newbie and would really appreciate your help.

If you have seen most of the the videos on kickstarter they have this slight grayish\grainy look.

example are youtube.com/watch?v=LmpeURi3cJY

I have attached some sample images also.

I want to make a video with that kind of feel. Do you think it is done with some special camera setting or done post processing using
some software

thank you guys
