Explained in http://x264.nl/x264/10bit_01-ateme_pierre_larbier_422_10-bit.pdf and further documents at http://x264.nl/. Would like to know what applications recognize this format though, and how would it be incorporated in a workflow involving standard NLEs (e.g. Avid MC or Sony Vegas). Would it have to be transcoded to e.g. DNxHD first, and if so then how (what app etc.)?
