Blackmagic codecs

[Noe Marti]

You should use the “Apple uncompressed 8 / 10 Bit” codec. The codecs you listed are mainly for compatibility of other products (voodoo cards and others). RGB 10 Bit is not compatible with all Decklink Cards.

Hi

Kindly refer to this tech note for more information about the various codecs:

You should ideally be using the Apple Uncompressed 4:2:2 codecs for RT in Final Cut Pro. If you setup your project using the provided Blackmagic Easy Setups, it will use the Apple codecs.

Great Link, thanks,

Now I understand, but everything now leads me to one question, please answer if you can.

In FCP, in my sequence setting, I use apple’s uncompressed codec, and when I use 8 bit, everything is fine, in terms of real time. With 8 bit uncompressed 4:2:2, on the timeline when I open RT menue, I have all the options like Dynamic frame rates and Dynamic Quality, but as soon as I change that to 10 bits, the menue in RT desappears and only option I have there is to Play Base Layer Only or not to Play Base Layer Only. Does this mean that FCP can not work in real time with 10bit uncompressed?

Also a question about Blackmagic 10 bit RGB, why shouldn’t I use this codec, if with 10bit uncompressed 4:2:2 I still don’t get RT, this makes no sense, or it does? And also, I wonder, if I had Blackmagic HD Pro dual link, would that make difference in terms of RT? or is it just for capturing purposes?
