In my experience in image manipulation and commercial printing, a 
noise variance of only1% in the luminosity of an image is enough to 
remove visual banding. At that level the noise is almost unnoticable 
to the naked eye. I would be very surprised if it caused flickering 
in an animation. If anything, it would give it a slightly more 
organic feel. The only problem I would foresee is that it would screw 
with frame differential compression methods.
