I had one project that was shot with the Cion as primary interview camera. It had to intercut with a Panasonic (GH3 or 4 from memory) second interview wide, low light Sony a7s in caves plus RED close ups of lit spiders in a cave. (16 Legs is the doco if anyone has seen it).
Matching the Cion to anything was a chore. I went looking for a LUT to get me close but found nothing from AJA at the time. In the end I made my own set of nodes in Resolve. It did grade up nicely at times but it was such weird color science that it was always the camera that needed the most work to get close to anything else. I never really got it to match the GH which I thought looked nicer on skin tones in the end.
The editor shot the interviews with that camera and he didn’t really like using it the end. I doubt AJA will want to get involved in any more dev with getting other codecs on board. It was an experiment that probably only encouraged them to stay out of cameras.
