Rendering to BMC without Hardware
When I try and render to BMC 10bit from a After Effects without a Declkink card it defaults to apple codec and in Final Cut the clips are white. Is it possible to render to BMC 10bit without a decklink card?

Hi Simon,
This problem is unrelated to the presence or absence of DeckLink hardware. You should be able to render to the Blackmagic codec without hardware being present.
If you have installed the DeckLink 5.0 drivers, then there should not be a Blackmagic 10-bit codec in the list of available codecs. You would need to choose the (Apple) Uncompressed 10-bit codec. If you have installed the DeckLink 4.8 drivers, then there will be both an Apple and Blackmagic 10-bit codec. Unfortunately QuickTime suffers from a problem where it will sometimes invoke one codec even though you have specified another one and this can lead to weird problems. It is because of this, and upon Apple’s request, that we have standardized upon the Apple codecs in the DeckLink 5.0 drivers as this avoids such issues.
If you find you have both codecs installed, you could try temporarily removing the FCP Uncompressed 422.component from /Library/QuickTime/. Then launch After Effects and perform your render and see if that helps.
