Noise on glossy surfaces with bump

Hi,

the setup: a sphere with a glossy surface, and some noise used as bump. The camera is animated moving slowly towards the sphere. DL with max samples of 500 is used.

The animation itself is pretty clean, but there is some noticable noise going on in the highlights at playback.

is there any way to get around this without increasing the sample count?

Doesn't looks like a noise, specular on small details

Yes, Aoktar, you are right, should have explained that better.

Is there a way to get rid of the flickering in animations when dealing with such small details? Again, without increasing the sample count?

Adaptive sampling with more samples. It will concentrate to noised areas after some time until noise disappear
