That is interesting, smooth nearer top, degradation nearer bottom.
What were the 'samples' set to? And did you also use 'intervals', 'jitter',
'confidence', 'variance', etc.? Easier still, if you could just post the
media portion of your scene file that would answer all.
But basically, samples should be able to smooth it out. If the script has
intervals set to some small value though that could be the reason for this
happening I believe. v3.5 media method 3 automatically adjusts that if
intervals is left out.
