Comments.Text: What do you mean by *real* bitdepth? The bit depth is there in the specs of the codec - ProRes422-HQ is 10 bit. It's not something you can fudge.

  The Media Express software it ships with will let you capture video directly from the Thunderbolt port at 23.98p, 24p, 25p, 29.97p, 30p frame rates ([from the tech specs page](http://www.blackmagic-design.com/products/blackmagiccinemacamera/techspecs/))
  
  [From the Wikipedia ProRes 422 page](http://en.wikipedia.org/wiki/ProRes_422) you will get 10-bit sample depth, and High-Quality comes in at 220 Mbit/s for HD resolution at 60i
  
  Thunderbolt can handle 10Gb/s and SATA 3 can handle 6Gb/s so they will not be a bottleneck here.
