Hello Everyone 
.
Can anyone tell me what software was used to create the video tutorials that you see in ZBrush (the fish and the monster)?
…use a prog who record that is on the screen each some second or minutes 
Like this free one
Camstudio 
Pilou
I use a program called Camtasia studio and alot of people use this too.
Fraps in the other program that can record the screen also.
Type in screen video capture in google and im sure there are many more.
