Are you saying you will be converting from Raw to RGB/YUV color space? By SDI do you mean standard definition? ( As opposed to HDSDI ?) Are you going to transcode and then use the CPU with the Aja card as a virtual VTR?

I think that the fewest artifacts would mean using the REC709 gamma or Redlog LUT,  saving as uncompressed RGB 4:4:4 10bit log and doing color space conversions later. The other option is to export as DPX and use Aja's quicktime wrapper.
