Just ran into this problem for my shop, and came across this thread.
We’d also like the KiPro to support captioning in an SDI studio environment. What we found was that the KiPro would record Line 21 captions, but upon playback, would shift the captioning up one line to Line 20. In a pinch, I know that we could use a frame-sync to shift the KiPro’s output vertically one line, but the desired fix would be to have Aja support these units as a true VTR replacement.
