anim test, GI flickering quite much

[Fat Tony]

Hello
So i am doing some testing on a animation and i know this had to be discussed here like zilion times, but just when i though i got it, it came back.
I have this GI flickering in the animation, in quite random spots, on the balconies, right corner of the building etc.
Here is dropbox link of the preview, is not full quality but you can see what is happening. When i render on GPU it is super clean and smooth, but well DOF is not so clean and anyways we got farm, so would be pity not to use it.

If you wanna check the video you should download it cause drop is downsizing it a lot.

Thanks a lot for any kind of input, setting in screenshot.

Light cache subdivs are quite low. I'd try 2000 or even higher.

Mouse over the LC subdivs, and read the tooltip!

OK then ! will post update tomorrow

Since the only thing moving seems to be the trees in the foreground you could probably precalc the LC in flythrough mode then render the trees separate and composite.

This was only test scene, and i think it would be too much hustle to solve this. i have other scene where i also have multiple objects moving and there i couldn't composite so easily. It is quite simple animation all together but still, ... will so what this uber LC will do.

Definitely too low subdivs. If that will not solve - you can use BF for trees and precalc everything else. Doing like that usually when I have couple of objects moving (trees, cars and etc)

thank to all will run it over night and will post update tmrw

Yes, so LC helped indeed. It is Almost flawless. I had to be stubborn and put 2718 subd, but now it is pretty clean and render time probably didn't even change.

Thanks a lot
