UE for Animation Production

Hi, I am new to Unreal Engine. Testing the possibility of using this great package for animation production. I like the look of the output and the speed at which that can be achieved with the sequencer. I am improving by the day. But curious to see some outputs if anyone is testing out. I had seen the kite demo. I am having problem with anti-aliasing. Kindly suggest the setting for rendering a 4K/UHD quality output that can be used in a movie theater. Thank you.
