One of my editors just loves to use smooth gradients in his backgrounds. Every time I do an H.264 or x.264 encode those backgrounds show quantization steps.

I have never been able to find much on the criteria for setting Adaptive Quantization controls. No adjustment I have ever made to any or all of them has made the slightest visible difference in the output quantization.

Is there any sort of guide posted that I can look at or can anyone on this forum suggest anything?

Thanks, JP
