filtering flickering edges in an animation

I am trying to create an animation using a computer program, but my problem is that the program creates files that are showing a heavy flickering / edge aliasing when the rendered object is far from the camera. There is no option to solve it inside the program.

What I would like to ask is that could you recommend me some Avisynth filters, which could filter out these rough edges?

As far as I know, there are two problems present with these renderings:

- There is no antialiasing, so the edges look rough when the object is far, even on still images.
Here is a 100% crop from the original image, when it is far from the camera.




- During animation, there are small white dots appearing. This would not be so visible with only still images, but in an image sequence this is really annoying.
I have uploaded an mp4 encode here:

as well as to Youtube (these small flickerings might get lost due to Youtube's recompression)

Could you recommend me some filters, and some best values for processing sources like this?
