Re: [Avid-L2] Re: H264s (or other codec QT) for client review with correct color.

Thanks, what have you found to be the best path to bluray in a file based environment without introducing quicktime gamma issues.

I have only used Toast to burn bluray discs.

Anyone have experience going proresHQ->bluray with toast?
