So presumable it does support Main profile then, since that wasn't 
mentioned in the list of unsupported profiles..

I'm trying to figure out if the weighted prediction is pretty much as 
good as it gets; I've seen several clips that don't encode gracefully 
when there is luminance fluctuation caused by camera auto-iris.. Having 
tried multiple other AVC encoders and getting the same results, I'm 
wondering if this is a limitation of the AVC design/spec (the same clips 
encodes with much fewer artifacts when using another 'popular' codec).
