Hi Oshian
I just used the defaults for my QT anim, maybe it would be worth while using a different codec

Detail blending is set to "0" and Micro vertex and detail jittering are both "ticked".
The high spec on the stones was a mistake, it don't work too well and is quite distraction to the rest of the scene.
For the next stage I need to build some models (once my house guest gives me the time

) and create a longer camera path.
Thanks for the feedback

Richard
