Which KiPro? I don’t have an answer for you directly but I’ll tell you what I know about our KiProRacks. I can control them from ancient DNF controllor via R422. The same controller we used to control our Betacams.
Also, the KiProRack does not record closed captions, at least I’ve never to get any our of it. The only way AJA says you can get it is to play in real time our of the unit. I still couldn’t see captions in Adobe Premiere.
I’m told the KIPro Ultra (that we have in our truck) does record captions and they are present in the files you retrieve from it.
