How long do you have to wait before the graininess has reliably become 
unnoticeable?  That's a question I need an answer to before I can use 
any unbiased renderer for animation work.  I need a renderer that won't 
give me a picture unless the quality is consistent from one frame to the 
next.

With scanline and ray-tracing renderers, there comes a specific point at 
which the renderer is *done* with the image and is ready to render the 
next image.  Unbiased renderers are never really done; they just go 
until the user decides the quality is good enough.  Sure, the user may 
be able to set the renderer to go only a certain amount of time, but 
except for a very short clip, and only after rendering a couple of 
frames in that clip, can the time required for each frame be predicted 
with any meaningful reliability.

John
