How to usie anti-aliasing?[solved]

Hey guys!
I got problem for rendering with HLAE. Before I used HLAE, I turned on Antialiasing - FAXX. Then I opened HLAE and entered all the commands from this video link and rendered it. The graphic looks smooth when I was using HLAE, but the result has no effects of smoothness after rendering. Did I do anything wrong with it?
