Keep in mind that rendering in DNxHD will clip the whites at 100–at least it does if you render thru AME–

Stardom SohoTank ST8, an Atto r380 or 680, and 8 Hitachi A7K series drives will serve you well–running in my work facility flawlessly for over a year now. And forget the Highpoint stuff–you need this to work and work for the long haul.

If you export using RGB color levels rather than 709 your issues should largely be fixed–the DNxHD codec will clip the whites to 100IRE but otherwise it should be OK–conversion issue with Avid codecs and Adobe apps–perhaps a different exchange codec will give a more exact match?

EVGA 03G-P3-1595-AR GeForce GTX 580 Classified would be a great choice–eVGA makes fab cards and their support is great–I’m running one of their older GTX285’s on my system and the performance is terrific.
The MPE does NOT yet work with the new Kepler cards yet (600 series) so if you are needing something now the 580 I’m sure will give you great results… -
John–
The export setting is within the MXF OP1a format list. I did a test encode of a PrPro sequence. It encoded fine and imported without issue back into PrPro–HOWEVER–Sony’s XDCAM Browser app did not recognize the file properly and would not open it. You should definitely try a test encode to make sure whatever playout-device you are encoding for will recognize the file. I am using CS 5.5 on a Windows PC.

The export for XDCAM is under an MXF option–my machine is at home so I will check this out later this evening and get back to you–your ProRes idea would also work but even better would be filing a feature request for ProRes export from within PrPro–more and more it seems as though manufacturers are incorporating ProRes in their devices so hopefully Adobe will get in on the action.
-
As Tapio noted–the support in PrPro for both Aja and Blackmagic cards is lacking at the moment–my own feeling is that you are wasting effort at this point in time in trying to resolve your issues until Adobe/Aja/BMD issue driver/software updates.

You can export to XDCAM HD without any additional codecs thru AME–ProRes ENCODING is currently only available on the Mac
platform thru Final Cut -
Jeff–
I have also been researching which vendor to go with for PrPro and it seems that at least Aja’s cards are still problematic with PrP, even with drivers having very recently been updated–see Walter Biscardi’s post here—

Malcolm–
At our facility we’re running SohoTanks w/ ATTO R380’s with Media Composer Nitris DX hardware and get terrific performance, currently 500+MB writes and near 600MB reads, with our arrays half-full (6.5TB total)–either the 680 or 380 will work great–ATTO costs more but the performance is there and the integration is trouble-free. ATTO’s support is outstanding–they’ll happily (and quickly) answer any questions you have.
