What causes the "flickering light" or "water refraction"
effect on an animation? I have encountered this many
times. It is a cool effect if my intention were flickering
candle light or 'light through a waterfall', but
no...I want steady lighting here.

My intuition is that it is some mathematical 'rounding'
problem caused by not enough decimal places....that the
subtle change between one frame and the next 'throws'
some calculation into a state that pushes
values up or down too much.

Or, I could just be making a stupid newbie error!

Short one-second animation
Frame rate: 30 fps
Scene uses only one light at full power, pure white
Light is infinite, not animated.
High res texture and bump map
Render time: 2 min per frame at settings (see below)
Rendering out to image files,
opening in Quicktime to make movie.
Click here for clip (2.5 MB Quicktime) opens in new window

Settings:

Any wisdom welcome.
