ok

I'm gonna copy-paste this from my comment on your other post since you don't seem to be listening.

Two tips for rendering, render as an image sequence, not a poster, there's tutorials for that out there, but before you render, make sure that progressive refinement is on and right click the viewport and click on render settings, then set the motion blur and depth of field samples to 128 or higher, it'll remove the grain from the ambient occlusion.
