AJA io XT: how does it handle ProRes?
In an earlier post I tried to clarify how io XT handles ProRes. However, the answers were not fully covering my questions.
In the meantime I got a clear answer from AJA support - most probably there are some of us being interested in this topic! Here we are...
Hi colleagues from AJA support!
Unlike the io HD the io XT has no internal hardware support for ProRes. While capturing it streams uncompressed video to the connected Mac. And this Mac has to have at least the performance to do the ProRes (or whatever other format you like) encoding on the fly. If not, you have to capture uncompressed video to a good performing RAID, doing the ProRes (or whatever) encoding after capturing. I have no idea whether a Thunderbolt MacBook Pro has enough performance for real-time ProRes HQ encoding for instance. Or a Thunderbolt iMac in general. Are there any io XT buyers who could bring some light into this topic?

I responded in another thread on this.
I am using my IoXT with15 and 17" Laptops, storage is a Pegasus R6 Array over TB.
(in RAID6 I am seeing capture and playback speeds over 500MB/s)
With the Shipping release of the IoXT software:
I can capture uncompressed 1080 video as 8 bit & 10 bit
I can capture uncompressed 1080 10b, as 444 RGB, as 1080 60p, as DPX or Tiff frames from Dual Link Sources
I can capture from those same single or dual link video sources in all flavors of PR from Proxyt up to PR444.
I am one of the few people that got to play with an IoXT prior to release, becuase of TB your world is about to change.
