help me on rendering a movie

Hi dear friends
I got really confusing about massive amount of parameters in unreal :rolleyes::eek::smiley:

I wanna render a movie in unreal for archvize or animation
1- first, how should i set my camera to stay in it in play mode. when I press play button it jump to another camera.:mad:

2- my second problem is that even i search for maximum quality in rendering but the anti-aliasing effect in final render is terribly low :eek:
does unreal is able to render a fine anti-aliasing or not?
