I am new to programming in Mac OSX. I need to do a very simple screen 
recording application similar to uShow, ScreenFlow and others, but 
with very basic settings and simple features. I would like some 
directions on where can I get some references on API areas, sample 
code, or some other information that might help me on this task.

I suspect that it is something related to the QuickTime API, but I 
would really appreciate some help here.

I have done this in Windows, but in Mac i am totally lost.

Anybody has any sample code or could tell which API I should start 
taking a look at....
