Can't find answer anywhere! clip capture

Nobody seems to be able to answer this simple question.

While playing a movie I want to capture certain clips. Just simply start
capture, stop capture and save clip to disk.

Nothing I have can do this Moviemaker, Media player, Nero Showtime etc.

Can someone please tell me how to do what everybody on youtube can do.
