Re: [Avid-L2] faster Go Pro injest

They are definitely doing something different with H.264 than your typical
DSLR (canon 5D, 7D, etc.), which work quite well with AMA. Probably a more
complex GOP structure. More CPU horsepower helps.

Premiere Pro and FCPX can deal with it quite well. Will test with MC 7 on
my home Avid, in the coming week...but I am not hopeful. I think
improvement will come when Avid introduces the new video engine in the next
major release.
