If you are taking of the very thin vertical lines flickering during the animation then increase the min sampling. Also turn in Jitter

 

I agree with brian ints not too clear what the problem is so I am taking a stab in the dark

 

 

Nice rendering by the way.

Before any thing,thank you Brian and Justin for your help,My problem is that during the animation the front faces of the fertical boxes of the building it seems like it is disappear and appear again from a frame to frame making bad effect afriend of me told me that it is reated with the photon solution whish i am not expert enough with it so what is the best Gi and FG sitting for that scene although i raised the min sampling up to 4,at the end Thank you
