Question: QT uncompressed 10 bit codec
Uncompressed 10 bit codec for QT.
Finally found the answer.
You need to download any version of "Desktop Video" to install the Blackmagic uncompressed 10-bit codec. Go here http://www.blackmagic-design.com/support/ and select any DeckLink product from the dropdown menu to go to the Desktop Video download page
Hope it helps someone, took me a month to get it sorted.
