Help in reducing shimmering during animation
I'm working on an animation where the camera moves along a spline. The object it circles is comprised of two cylinders - the inside cylinder is slightly reflective. The outside cylinder has a transparent glass type surface.
During the animation, there is a very prominent shimmer / wobbling effect on the glass that most likely occurs from reflected light. I'm ok with this effect on the glass, but it also seems to be distorting the edges of the inside cylinder - and this has a unsettling, disturbing feel to it.
Can anyone offer advice on what parameters I might change to eliminate or reduce the shimmering on the edges of the insider cylinder?
sample animation can be downloaded from here:

In addition to various lights, these are the main settings I am using:
Camera:
Perspective: 38.717
antialising mode: edge
min samples: 1 x 1
max samples 4 x 4
Tolerance 0.050
Using HDRI tag
Radiosity:
intensity: 1
samples: 200
Diffuse Smatterings: 5
Specular Smatterings: 2
Using Fog tag
Outside Cylinder
The outside glass cylinder has a render tag with following checked:
visible for primary rays
filter textures
And it uses these material settings:
Color
ambient: 0
diffuse: 0
Specular
color: 3A3A3A
Emissive
Color: 3A3A3A
Reflection
color (white)
Intensity: 0300
angle: 0
samples: 16.0
Transparency
Color (white)
intensity: 0.950
index of refraction: 1.500
use alpha channel: not checked
fresnel: checked
Inside Cylinder
The inside glass cylinder has a render tag with following checked:
cast shadows
visible in radiosity
visible for primary rays
receive radiosity
filter textures
And it uses these material settings:
Color
color: 8A6B59
ambient: 0.970
diffuse: 0.950
Specular
color: black
Emissive
Color: black
bump mapping
intensity: 0.040
Reflection
color (black)
Intensity: 0.300
angle: 3.0
samples: 8.0
Transparency
none
