Static Noise in Animation Render

I notice that when rendering an animation there is static noise that appears as a kind of layer above the animation. (Using Cycles and Blender 2.74) I googled and found some pages that said to set the sampling seed to #frame/2 and it is supposed to change the noise in the animation every other frame. I have not found this to be the case unless I have misunderstood. Other than increasing the samples (which I will do later on) how do I get rid of this static noise? If it’s there at a low sample rate it will be there at a higher one albeit much less noticeable.

I misspoke. I am not looking to eliminate the noise in a low sampled animation - I expect it to be there. It just seems like the noise should “flicker” rather than remain static and be somewhat annoying.

Kept searching and found this on youtube. Exactly what I was looking for. Cheers!
