While there are many puzzling choices in the design of the DNXI/O, the one thing clear is they had to release something to replace the Nitris DX, which was discontinued and only partly supports the current MacPro. Many facilities are still HD and deliver HDCAM, HDCAM SR and D5. I guess they could have left it to existing third party Open I/O, but none supported all Avid features

This is somewhat confusing to me. Other than as you say live capture, which I will never see in post, this box accelerates nothing not even playback? I would have thought that if it can Transcode assist on the input it would do just the opposite on Playback. This seems silly, sad, annoying or all of the above. So it's just a break out box with no acceleration for any Post tasks unless I am brought a 4K playback device?
Would a 4K playback device be practical given how file centric things seem to be in the field? I haven't followed closely but doesn't BM make a vtr shuttle device and AJA a 4K version of the KiPro recorder unit. I'm sure there are others but all I've ever seen in my very limited 4K world are files. I haven't worked directly with KiPros but I believe our AEs have received drives or cards from the units that had ProRes LT files for out Pelco cameras. Does the BM vtr emulator and or the KiPro or other units in this category support RS-422 control? I would assume so but haven't worked with the units. That would allow me to capture like tape device and capture to DNxHr in real time. I didn't clock my recent Transcode with ama linked True 4K from a Panny Cam shot in Vlog but it saturated the cores of my MacPro Tower running 2,000 to 2,200 of CPU percentage according to Activity monitor. I had something like 12 to 14 hours of material which took overnight although I did run out storage space it seems like it went reasonably fast. I'll have to look at the date stamps to get a better handle. I seem to recall the transcodes to DNX 36 seemed to be taking about 3 times real time but they were having so many crashes and stall in that process it's hard for me to access that.
Well at least the DNxIO will work with BM software and I assume others through the BM/Avid Desktop software. It's nice to know that every pain staking hour watching the progress bar I'm helping keep Avid from having to tap into the Bonus Fund that is clearly more important to the corporate folks than developing improvements to the product.

Accelerated Rendering? No. Accelerated playback? No. Accelerated export? No.
Just transcoding while capturing. Yup that's right in a world that is moving quickly to being tapeless we have an I/O box designed for tape or live capture Transcoding.
